Poly propylene pipes (PP) Among the specialists today are considered the best pipe products. They have good technical and performance features and differ in their appointment, color, quality and scope of application. They are used for laying, both domestic and outdoor engineering communications.
When choosing polypropylene products, attention primarily draw a marking applied to them. This is explained by the fact that the technical characteristics of different modifications may differ significantly. For example, not any polypropylene tube is suitable for systems operating at high temperatures and elevated pressure.
The current classification of polypropylene products now implies their division into 4 groups. Their marking consists of two Latin Pn letters and two digits that make up a number denoting the pressure to which PP pipes are calculated.
These values \u200b\u200bare applied to the surface of the products:
It is the properties of polypropylene pipes that make them in demand among developers, both multi-storey buildings and small country households.
Among the positive features of polypropylene products should be noted:
In addition to the advantages of polypropylene pipes have drawbacks:
Since the degree of linear expansion is sufficiently high, when installing the pipeline, it is impossible to allow SP pipes - for this point of attachment on the wall should be located with small intervals.
To choose this product without error, you should consider four important moments In addition to the marking of products, which was described above:
Products with marking PN20 Specialists are not recommended to be laid by a closed method, because as a result of their deformation in the layer of plastering, cracks will appear. As for the use of PN25 products, it can be mounted in both ways - open and closed.
The open option will not worsen the interior of the room, since the PP tube reinforced well holds the form and it will not be necessary to bend it. Thus, the method of laying a hot water supply system depends on the coefficient of linear expansion of pipe products from polypropylene.
In the world market, PP pipes are presented in the next high.
PPH - Type 1. These products from polypropylene are considered the most simple from the entire range of products manufactured by the modern industry. Their scope of application is a gasket of cold water structures, ventilation systems, Proming pipelines.
PPB - Type 2. This variety Polypropylene rolled pipes are made from a complex block copolymer. Such products are involved in the arrangement of pressure systems for the supply of cold liquids and heat supply. Also, this product is used in the production of shock connective elements with high strength.
PPR - Type 3. The technical characteristics of the PPR pipe are based on the production of copolymer by rand. Its introduction to industrial production has been world importance. Initially, he had a PPRC abbreviation - a copolymer polypropylene by random, in the future it was reduced to PPR. From products related to this species, the water supply systems of cold and hot-type are laid. It is this product that will be involved when creating a warm water floor.
Such a molecular structure provided the following characteristics of the PPR pipe:
The technical characteristics of polypropylene PPRC pipes made their alternative to galvanized metal products. Among them are products that are reinforced by aluminum or fiberglass.
PPS - Type 4. The raw material for the release of this product is complexly flammable high-strength polymer. The maximum permissible temperature of the working medium of these PP pipes is 95 degrees. Experts consider them the best option of unarmed single-layer products for heating systems.
Polypropylene tube rental is released in four color solutions.
Description of polypropylene pipes of different colors will help make the optimal choice:
Use such a type of pipe products to create engineering communications on wastewatering and sewage system, as well as structures for disposal of atmospheric precipitation and groundwater. The maximum permissible temperature of the fluid, which moves along corrugated PP pipes, is for permanent drains + 60 degrees, and for short-term no more than 100 degrees.
Pipelines that build with the use of corrugated products are mounted in open trenches and a trenchless gasket method. Transitions are shut-off using reinforced concrete wells. No additional equipment and special equipment are required for laying a large diameter corrugation.
Now industrial enterprises have mastered the production of two-layer corrugated pipe products from polypropylene.
Their positive qualities are:
Among the disadvantages are exposure to accelerated aging.
In the process of installing the system of pipes made from polypropylene, the thermal polyfusion method is used - the welded parts are heated and quickly connected using a soldering iron.
Some manufacturers equip the tool for welding two, and not one heating element. In this case, the power becomes enough to heat the segments of the pipes of different diameters without any problems.
But this advantage can simultaneously become a disadvantage. The heating is performed at once with two elements capable of overlaying plastic and overload the power supply network. For this reason, the second heater should be used only as a spare when the first fails.
The duration of the heating stage depends on a number of factors:
After heating, polypropylene retains its plasticity for a short period of time. In seconds, it is required to fix the connection, not allowing the appearance of overcasts. Optimal temperature For heating is + 260 degrees.
To ensure a reliable and durable compound, the polypropylene needs to warm up much, but the excessive heating is able to lead to the loss of the shape of the product. Therefore, the time should be controlled during which welding is performed.
Depending on the cross section of PP pipes, it should be:
It is not enough to heat and connect pipes from polypropylene, they should still be able to cool. The period of fixation in time should last as much as the heating phase. If the execution of this process, as a result of the rush, complete earlier, the compound will exploit.
The technology of performing welding PP pipes refers to difficult work. Not only the heating time has great importance, but not compliance with the rules for performing soldering.
The main nuances of the process are as follows:
Most developers, having familiarized themselves with the advantages of polypropylene tubular products, stop the choice on these products. Finance, spent on the purchase of PP pipes, will surely pay off over time.
Polypropylene Pipe: Polypropylene PPR, Specifications, PPR Weight, Parameter, Properties, Description
Polypropylene pipes are manufactured according to GOST and their dimensions are regulated by the standard. The diameter of the inner highways is from 10 to 1200 mm, the wall thickness depends on constructive features. Classified: in the composition of raw materials, pressure, appointment.
Manufacturers produce polypropylene pipes of different diameters
Polypropylene pipes are conquered by new spaces every year - they are used in many industries: mechanical engineering, agriculture and, above all, in heating, water supply and sewage systems. The dimensions and configuration of PP pipes are regulated by GOST. Products are divided into types depending on the qualitative composition of raw materials, namely on the degree of modification of the main polymer with various additives.
In the marking of PP products, the designation N25, N10, etc. This indicator makes it possible to assess the stability of the material to the pressure of the liquid passing through the highway.
The following types of polypropylene pipes distinguish:
Currently, there is a reinforcement of a fiberglass polypropylene highway. This avoids the separation of hydroflows during operation, and during installation - the loss of time to stripping sections during welding. Systems with reinforcement of fiberglass mesh are most preferable, as they provide quick installation, deformation resistance, increased service life without repairs.
What are the diameters of polypropylene pipes? Parameters depend on the temperature and volume of the transported fluid, its pressure on the walls. First of all, the product configuration is selected depending on the purpose. For each type of classification, there is a table of the size of polypropylene pipes, according to a suitable product.
What are the sizes of highways? The physical parameters of sewerage systems, heating, water supply directly depend on what they are intended for. The diameters of metal and polypropylene pipes differ slightly, but in favor of the latter. Plastic parameters - less, and the service life is significantly larger. In addition, the polymer wins the aesthetic properties and corrosion resistance.
The diameter of the PP tube is selected according to the results of the calculations of the lifeline. When choosing steel, copper, polymeric products, you should carefully treat marking - some types are denoted by internal diameter, and some are external. In the labeling of polymer pipes, diameters are indicated only by external.
The inner diameter of polypropylene pipes seload by elementary calculation with the source data:
The diameter of polypropylene pipes for the water supply of a private house or the mansion is calculated by the formula:
where V is the speed of the passing flow, m / s (taken from 0.7 ... 2 m / s);
π - the number of pi, equal to 3.14.
The diameter of pipes for the private house water supply in practice is taken by 20 mm by default. For a multi-storey building at each stage of construction, various diameters of polypropylene pipes are used on the basis of a refined calculation: for the flow of water into each apartment, each entrance, to the house, quarter, microdistrict uses various highways. Accordingly, the higher the water consumption, the larger sizes are accepted.
In practice, the following sizes of polypropylene pipes in MM are used in multi-factor houses:
Polypropylene polypropylene pipes are used in organizing water supply, heating, sewage to homes, residential neighborhoods, public buildings, sports complexes, hotels, for industrial needs. For example, pipes for water supply with a diameter of 500 mm are used for the flow of cold drinking water From cumulative pools to the areas of the metropolis. For transfer of heat carrier PP pipe big size Not used due to a large thermal load, which contributes to the softening of polymer highways.
For ventilation systems and drains of industrial structures, polypropylene pipes are used, the dimensions of which exceed Ø400 mm.
For independent installation Heating, water supply and sewage systems in a private house or apartment, it is important not only to choose the right sizes of highways, but also to connect them correctly. This requires special welding equipment, some skill and ability to use it. Therefore, it is better if professionals will be engaged in the design of communications and their gasket.
In the article, we briefly described the classification and the main parameters of polypropylene plumbing highways used for the device of external and internal heating, sewage, ventilation, water supply. The range of products of various diameters and destination allows you to implement complex construction objects, perform the strapping of DHW, HPW and heating aesthetically, quickly, reliable.
Polypropylene pipe diameters: dimensions in mm, table, internal diameter of PP pipes
This article will feature polypropylene pipes for water supply with a description of their basic properties, species and applications. Along with metal-plastic pipes, the inner water supply or heating system from polypropylene pipes may not even have professional training person. It is enough to get the necessary minimum knowledge to ensure that the quality and appearance of pipelines in your home, bath or other individual buildings would meet the highest requirements.
Recently, the installation of polypropylene water pipes received wide use During the construction of individual houses. 
It is explained by this accessibility and low price of all components, simplicity and reliability of installation, long service life (over 50 years), absence of corrosion and increments, visible external species, the possibility of use in heating systems, hot, cold and drinking water supply.
Depending on the modification of polypropylene, three types of pipes are produced:
According to GOST R 52134 -2003, regulating the use of thermoplastic pipes, all three of the above types of polypropylene can be used in the production of pipes for water supply and heating. Standards of countries such as Germany, United Kingdom are also allowed to use them for pipelines, taking into account all sanitary and hygienic requirements.
In accordance with the purpose of the water supply, the following classes of polypropylene pipes are produced:
Operating temperature MAX, C
By its structure, polypropylene pipes are produced both from solid material and aluminum reinforced or fiberglass. Pipes made from solid polypropylene are applied only in hot and cold water supply systems, and water supply from water sources, and reinforced can be used in all systems, including radiator heating.
Compared to whole, reinforced pipes have a significantly lower temperature elongation. So, for reinforced fiberglass pipes, it is two times less, and aluminum is four. Aluminum perforated interlayer reliably protects against harmful diffuse oxygen penetration through the pipe walls into the coolant or water. These factors are especially important for heating a closed view with a large length of pipelines, when the amount of oxygen in water can achieve such a value, which damages the sanitary equipment.
As a rule, the pipe marking should contain the internal voltage value in MPa (1 MPa≈10 kg / cm²). For example, PP-R 63, where the number "63" means an internal voltage of 6.3 MPa in a pipe at 20 ˚C, in which the manufacturer ensures that it does not destroy at least 50 years. This property of the polypropylene tube is called minimal long-term strength and is indicated as MRS (Minimum Required Strength). The higher this indicator, the stronger the pipe. Therefore, it is necessary to take into account that incorrectly chosen pipe may not withstand the guaranteed life.
The scope of the use of polypropylene pipes in individual houses, baths and economic buildings is extensive - from hot and cold water supply to the arrangement of radiator systems and outdoor heating. With their help can be connected to pipelines from different materials: steel, copper and metalplastic. Large service life allows you to put them with confidence in both open and closed systems.
How to choose a pipe from polypropylene
However, it is important to correctly make a choice in an extensive assortment of pipes offered by many manufacturers. Here are some criteria that need to be guided by purchasing:
Polypropylene pipes, mm
Note:
pN25 pipe is manufactured with a reinforcing aluminum layer, which can be a simple or perforated interlayer with through holes. The perforated layer ensures a reliable connection of all layers without the use of glue. The aluminum layer may be as shifting to the outer surface of the pipe, so symmetrically relative to the inner and outer surface. This affects only the process of assembling pipelines, which will be described in the relevant article.
What the company "Valtec" offers:
What is better - polypropylene or metal plastic pipes
And in conclusion, a few words in favor of choice exactly Polypropylene pipes for all pipeline systems.
There was a time when I used copper, and steel, and metal-plastic pipes. Until I learned about polypropylene, and did not spend from them in my bath and house, and heating, and cold, and hot water. Not a single marriage in connections! The work is clean, fast, reliable, "without noise and dust", in one word, pleasant in all respects. The cost of fittings and pipes themselves, compared with other species, funny. It is not necessary neither pipe bending, nor gas waken, nor propane, nor other expensive tools and materials.
Just needed - a special welding machine and cutter. Although you have to sacrifice your money on their purchase, but it is not comparable to those costs that will be on the installation of pipelines from other materials, especially copper. And the purchased tool is always useful when repaired or upgrading pipelines not only in the bath, but also in your home. However, it is better to choose - polypropylene pipes for water supply or any others - to decide yet.
Polypropylene pipes for water supply and heating, let's go
Not everyone knows that at present there are many types of polypropylene pipes, characterized by technical characteristics, quality, appointment and color. But these products are increasingly used to arrange domestic water supply networks, and, practically, the steel counterparts were supplanted. On their basis, you can create engineering communications with an increased working environment - hot water supply and heating systems.
Today, quite a few types of polypropylene pipes are made for use in a variety of spheres.
The first thing to pay attention to when selecting these products is what they have labeling. The fact is that the technical characteristics of polypropylene pipes differ from the modification to the modification. And this factor imposes significant restrictions on the scope of their application. In particular, not all of them are capable of working at a considerable pressure and high temperature.
The existing standardized classification of polypropylene pipes is divided into such products into 4 groups. Their designation contains Latin listers PN and two digits. This number displays, for which the pressure is calculated pipes from polypropylene.
PN. 10. Systems collected on the basis of products of this http://trubamaster.ru/vodoprovodnye/prokladka-polipropilenovyx-trub.htmlgroups, withstand pressure up to 10 atmospheres. The answer to the question about the maximum temperature of the working medium is unambiguous: + 45˚С. These numbers are indicated on the surface of the pipes. With the help of pipe products of this type, we create communications for transporting only cold liquids. The main difference is thin walls. "Thanks", the technical characteristics of the PN10 polypropylene tubes are not widely used for laying the pipeline in apartments.
PN.16 . Polypropylene pipes designated by such a sequence of characters withstand pressure up to 16 atmospheres, you can transport liquid with a temperature of + 60 ° C. These polypropylene pipes can be chosen solely for "cold" highways. In addition, it is inherent in a rather high temperature deformation coefficient that in the pressure pipelines of heating and hot water supply is unacceptable.
Determine the type and purpose of the pipe can be labeled on its surface.
PN. 20. What pressure will endure the pipe from polypropylene, in the designation of which there is a combination of symbols, we already know - 20 atmospheres. And the water temperature + 95˚ is not terrible. The technical characteristics of PN20 polypropylene pipes allow them to use hot water supply.
Important! Due to considerable temperature deformation in pressure heating systems, they are currently not used. When a high pressure fluid is transported under such a pipe with a temperature approaching extremely permissible, it behaves and bends.
PN.25. These are already full-fledged pipes for heating from polypropylene. The temperature of the coolant can reach + 95 ° C. The answer to the question of which pressure is holding a PN25 polypropylene tube, is clear - 25 atmospheres. As a raw material, a composite material with reinforcing inserts is used. Such may be a drop-in fiber or aluminum foil. Both types of layers not only improve the strength characteristics of polypropylene pipes, but also reduce the temperature deformation. Even during the transportation of water with a maximum permissible temperature under high pressure, their linear dimensions will not change. Therefore, reinforced products were widely used in pressure pipelines. Another important factor: compared with a thick-walled pipe from polypropylene, installed in similar highways, heat losses in metal-plastic products are two times lower. But in terms of frost resistance, these types of pipes are comparable.
The technical characteristics of the polypropylene tube, which made it one of the most sought-after types of building materials, are due to the amazing properties of this polymer.
One of the advantages of polypropylene pipes is the installation: with a fairly simple technology, a solid and durable connection is obtained
What features of polypropylene pipes allocate experts? There are several of them:
Not the last role in high demand, taking into account the characteristics of the climate of our country, the frost resistance of pipes from polypropylene caused by their low thermal conductivity plays.
Polypropylene pipes are resistant to low temperatures, and for their storage and operation does not require special conditions.
Above the pluses of polypropylene pipes were indicated. But, as always, without minuses here either does not do. The main ones are:
Tip! Taking into account the expansion factor when installing the pipeline, guide the special installation rules. In particular, do not allow pipe sagging - for this you need to place the fastening points on the wall with small intervals.
For the correct selection of these products, five moments must be taken into account. The marking of polypropylene tubes has already been discussed, so there are 4 important factors.
Maximum temperature. The choice should be done based on the intended value of this parameter of the coolant, taking into account the labeling of polypropylene pipes. As mentioned above, PN25 is the best choice for heating systems, PN20 - for hot water, PN16 - for cold water supply systems.
The usual home water supply can be mounted from a small diameter pipe.
Diameter. It is necessary to select it, taking into account the technical characteristics of the pipeline system being created. The best polypropylene pipes for the apartment wiring are products with a diameter of 20 and 25 millimeters. For risers, it is better to use products with a cross section 32 or 40 millimeters. The thick-walled polypropylene tube of large diameter is used for the main pipeline mounted in the basement of the apartment building.
Maximum allowable pressure. If we talk about use in everyday life, almost all types of pipes are suitable, including the product of the PN10 brand. As the service life is connected with pressure and temperature, consider on the example of this pipe.
Temperature expansion coefficient. We already know that polypropylene pipes are such products whose geometry changes at high temperature of the transported fluid. Changes relate to the thickness of their walls. And this is critical for such a parameter as the throughput capacity of the pipeline.
PN20 type closed package is not recommended. After all, its deformation can cause cracks in the layer of plaster. But the use of polypropylene pipes like PN25 allows you to lay and closed and open. In the latter case, the interior of the residential premises will not deteriorate due to the absence of bending of these products. After all, the pipe reinforced from polypropylene is perfectly holding its shape.
Important! The characteristic of polypropylene pipes "Line Expansion Coefficient" determines which method of gasket hot pipelines should be selected.
As for the service life of polypropylene pipes, then proper use Each of them will serve at least five decades.
Water pipe, laid inside the walls, will not spoil the view and style of the bathroom, but for this method of gasket you need to choose strong pipes
This world market segment is represented by the following varieties of polypropylene pipes:
Polypropylene pipe rental is represented by four colors. They are white, gray, black and green. Based on white or gray polypropylene pipes, various engineering communications are mounted, ranging from water supply and ending with an individual heating system.
Each type of pipes has its own color or labeling strip on the outer surface.
However, the disadvantage of white pipes is the impossibility of exploitation in the conditions of the street, since such products are characterized by low frost resistance. Already at a temperature of 0 ° C, the type of polypropylene is used for their manufacture begins to crystallize.
Helpful information! White pipes withstand pressure 25 bar! At the same time, the gray polypropylene pipes are inherent in the best tolerability of thermal loads.
Gray pipes also possess the following advantages:
In addition, gray polypropylene tubes are perfectly connected by a regular soldering iron.
From the existing data sorting product to create sewage, as well as drainage systems, it is recommended to use black pipes from polypropylene. Improved in the raw material production additives increase their technical capabilities. Of the advantages of plastic black tubes it is worth highlighting:
Currently, many owners country areas Interested in the question of which polypropylene tubes are the best for watering. The answer is unequivocal: green color. They are sold at such a low price that gardens simply may not pay attention to the strength characteristics of these products.
Such products of large diameter are used to build wastewatering systems, sewage, removal of rainfall (livnevka) and groundwater (drainage).
Polypropylene corrugated pipes are used in a variety of spheres - small diameter in demand for gasket power grid
Estimated for a polypropylene corrugated pipe Maximum value of the temperature of permanent drainage - order + 60 ° C, and short-term up to + 100 ° C., which is rare. Pipelines created on the basis of this product, trenchless gasket and in open trenches, and the organization of transitions is carried out with reinforced concrete wells. Moreover, no other structures, as well as special equipment for laying and installing corrugated steel diameter is not required.
Modern enterprises have currently mastered the production of two-layer corrugated pipes from polypropylene. Of their advantages, it is worth highlighting:
To weld products of this type, a method of thermal polyfusion is used. It consists in heating the welded parts followed by their rapid compound. This procedure is performed using a special soldering iron. Some manufacturers of such tools equip them at once with two heating elements, the power of which is enough to heat the pipes of a particular diameter. It would seem that this is a plus. But not in this case.
For high-quality connection of pipes using the thermal diffusion method, special equipment and clear observance of welding technology will be required.
Important! The heating simultaneously with two elements is able to overheat plastic and cause power overloading the power supply. Therefore, use the second heater should be used as a spare when the first fails.
Heating time depends on:
Material after heating saves plasticity very short time. For a few seconds you need to have time to fix the connection, at the same time getting rid of the distortion. The optimal temperature for heating is the mark of + 260 ° C. To provide reliable compound The pipe material must be warm enough. But excessive heating can cause a loss of form. Therefore, you should control the execution time of this operation. Depending on the pipe cross section, it is:
Heated and already connected pipes must be cooled correctly. Fixation requires the same time as the heating phase. If you hurry and stop the execution of this procedure earlier than the required time, the deformation of the compound will arise. Welding of polypropylene pipes is a relatively difficult process. Critical is not only non-compliance with heating time, but also failure to fulfill the soldering rules. The main ones are as follows:
Upon learning what is polypropylene tubes, most of our compatriots prefer to buy such products. Invested money will pay acknowledged by many factors. In particular, the low thermal conductivity of the material allows you to abandon the purchase and installation of thermal insulation. At the same time, heat saving during the transportation of the coolant is about 20%. That is, gas consumption in the autonomous heating system can also be reduced.

Modern, affordable and reliable solution for centralized and decentralized systems - polypropylene pipes for heating (PPR, PPR), conventional or reinforced with fiberglass, aluminum. Such products are characterized by resistance to aggressive substances and chemical solvents, durability, it is not subject to corrosive processes, so polypropylene pipes are so popular for heating.
The metal comes to change more modern material - Polypropylene for heating, which is a kind of thermoplastic polymer. Ten years ago, products were made of pure material and possessed not the most best indicators Purpose pressure and high temperatures. Today, the range of polypropylene pipes for heating has significantly expanded, each view has its own technical characteristics.
The characteristics of polypropylene pipes are determined by their type. Initially, PPR products were used everywhere - the most simple systems. The stated lifespan of them is much lower than the stated, due to the temperature and pressure of water, deformation occurred. Manufacturers modified the material and this classification appeared on the consumer market:
Before buying, carefully examine the marking in the first of them. Products necessarily indicate: PPH, PPB, PPR, PP-RCT. 1, 2 Type is not suitable for heating. Domestic manufacturers label products according to the standards of the GOST class of operation. For the heating system, only 5 class is suitable, and 3, 4 classes are used for the warm floor. Also on the lateral part of the product indicates the working pressure. The designation PN25 indicates that the pipe can withstand 25 atmospheres per day.
The construction market presents polypropylene pipes for heating from around the world. A huge number of manufacturers and their products can mislead an inexperienced buyer. The choice should not be based on whether the products are cheap or expensive, there are promotions, discounts and sales sales. Purchase should be carried out on the basis of the technical characteristics of the product and reliability of the seller. Czech and German companies deserved special consumer confidence.
Builders and repairmen with a high probability have heard about the high quality of Czech products from Vavin Ecoplastics. These products occupy a leading position in the ratings of Plumbing online stores. Experienced masters They know where to order products of this company on catalogs with delivery by mail so as not to overpay. One of the demanded options is the following:
To solve various problems and operating conditions, Vavin company produces several options for its products. With significant loads on the system, experts recommend using the following form:
Polymer systems for heating are a narrow specialization of the Plastic company, producing products under the trademark of RVK. Production is located in Russia, which provides affordable cost of products. RVK is made in accordance with European standards. Raw materials and equipment are covered from Europe.
Heating using RVC products is low heat loss due to low thermal conductivity indicators, long service life, minimal pressure losses. The quality of Russian products is provided not only by the relevant standards with raw materials and technologies, but also by specialists who constantly increase their level, adopting experience of colleagues from Europe. Fiberglass reinforced products - it is reliable and inexpensive:
Prices for polypropylene tubes and fittings from the Russian company Pro Aqua are available, while quality remains at the level. One of the main advantages that Pro Aqua products possesses are durability. Under normal operating conditions, the manufacturer promises 50 years of guaranteed life. Resistance to aggressive media, alkalis, high pressure and temperatures are necessary for the use of products for central heating circuits:
Three-layer polypropylene fiberglass pipes are one of the achievements of Pro Aqua. The main advantage of such products is the low linear expansion coefficient, which is especially important when arranging heating blocks. One of the popular options for fiberglass reinforced, is the following model:
The German company Banninger delivers products for heating and water supply from PP-RCT polypropylene. Banninger polypropylene pipes can be green or white. Products are characterized by high resistance to acids and alkalis. High quality products allows us to use it not only in domestic, but also on an industrial scale. Popularity in consumers won the budget option:
There is another option:
The German company WEFATHERM is engaged in the production of water supply systems and heating. WEFATHERM feature is the perfect smoothness of the inner surface. Such a property contributes to minimizing pressure loss. Experts argue that for the goods of this company is characterized by excellent resistance to pressure and temperature drops.
For a long period of existence, the company confirmed wear resistance, durability of pipes from the German manufacturer. Special attention deserves the fact that products are resistant to sunlight. For heating systems, it is often used:
One of the unique developments of WEFATHERM, which is becoming increasingly popular - reinforcement with fiber fibers. Such systems are easy to install, the material is not resolve during operation. For such products, the exceptional smoothness of the inner walls is characteristic. Low thermal expansion coefficient, environmental friendliness, high chemical resistance makes products reinforced with fiber fibers, ideal for heating systems. The only drawback is the price of the German manufacturer's products too high:
HEISSKRAFT is a Russian company. The manufacturer claims that pipes are made in Germany, but the plant is located in Pushkino Moscow region. Although such a deception of the manufacturer has already ceased to be a secret, PT Heisskraft continues to be popular with consumers, because the quality of the products is at a decent level.
HEISSKRAFT feature is that technical soot is included. The substance has proven itself as an excellent stabilizer for such products, therefore improves the technical characteristics of products.
For hot water systems, centralized and decentralized heating, Heisskraft has developed a thermo-stabilized fiber-reinforced fiberglass fiber. Such systems are used in multi-storey construction.
In the modern Russian market, polypropylene pipes for heating are offered dozens of companies from around the world. It may be difficult to understand the widest assortment. The main thing is to pay attention to the characteristics of polypropylene and the manufacturer's reputation, because the manufacturer's statement is not always consistent with the real position of things. Before buying polypropylene products, consider the following selection factors:
Plastic pipes have long been an excellent alternative to metal products. Such popularity is explained by the strength and durability of polymeric materials. In addition, polypropylene pipes have a composite structure, which allows the material to withstand high temperatures and pressure (without deformation), not subject to corrosion, do not respond to aggressive components.
In addition, the installation of such pipelines is made much easier: plastic is easily processed, soldier heat welding. In this article we will analyze the key parameters that will be useful as a home master and professional plumbing.
Given that polypropylene pipes are capable of functioning in almost any conditions, the products have a wide area of \u200b\u200bapplication. In particular:
Halfing of hot and cold water supply in multi-storey and private buildings.
Sewage.
Arrangement in the "Warm Paul" system.
Assignment of soil I. wastewater.
Creating drainage, irrigation and reclamation systems.
Ventilation.
Pneumatic systems.
Pipelines for transporting chemically active substances.
It should be noted that, depending on the application, various types of pipes are used. When operating conditions, these products can serve about 50 years old Without loss of functionality.

Polypropylene has a number of indisputable advantages over metal pipelines. These moments can be attributed to the strengths of the material:
Long lifetime. Manufacturers assure that pipes used in cold water supply may not be less 100 years.
Low weight. Polypropylene - lightweight material. If you compare products of similar length and diameter from plastic and metal, the first will be easier for approximately at 9 times.
Simple montage. A person who does not have special skills and knowledge can cope with the installation of such a water supply.
Increased noise insulation level. Pipes in residential building do not miss noises.
Resistance to corrosion. The inner surface of the pipe is processed by special technology, which eliminates the appearance of solid formations, which reduce the capacity of the pipeline.
In addition, it can be noted high resistance to low temperatures and dynamic loads. Such pipes do not need special maintenanceare implemented in an affordable price segment.
There are materials and some disadvantages. In particular:
The high probability of linear expansion is preserved, which requires installation special compensators.
Accelerated aging material under the influence of direct sun ray.
Low heat resistanceWhat implies the mandatory use of the insulation.
In addition, the vintage pipelines are not allowed, so the number of mounting elements is significantly increasing.
On the labeling of polypropylene pipes, you can learn about used for the manufacture of raw materials and technical features of the material. Above the designations that indicate the ability of pipes to withstand a certain pressure inside the highway.
Now consider the label, which indicates some properties of the material. In the construction market, you can find pipes such categories:
Ppb. - products with high resistance to mechanical damage and hydraulic manifolds used in "warm floor" and cold water supply systems.
PPH - Large diameter pipes, which are usually used when installing ventilation systems.
Ppr. - Universal products, equally effective in hot and cold water supply.
Regardless of marking, polypropylene pipes are made of plastic. However, manufacturers are usually added to the original raw materials active additives that increase the elasticity and thermal resistance of the material.
4 classifying groups are provided that are divided into operating pressure parameters. It looks like this:
PN 10.. Used to transport liquid low temperatures - to +45 Degree.
PN 16.. Are suitable for the arrangement of the gas supply system or fluid, provided that the temperature of the coolant does not exceed +60 Degree.

By types, products are divided into reinforced and unarmed. For the second group, reinforcement of such materials is allowed:
Fiberglass.
Internal reinforcement perforated foil.
External - aluminum layer.
Composite: Inner layers of glass - or fibrovolok.
only reinforced pipes are used to arrange hot water supply or heating systems.
Considering that the pipes of this type are used almost everywhere, manufacturers produce products in a wide dimensional range. The product sizes varies in such limits:
Diameter - from 5 to 400 mm. Small pipes are usually used when laying pneumatic systems, medium - private and multi-storey construction, large: arrangement of buildings where high throughput of engineering communications is necessary.
Length - standard value is 4 metersHowever, this is not a reference characteristic, remains at the discretion of the manufacturer.
Wall thickness - 1.9-15.1 mm.
It is necessary to clarify that polypropylene pipes can be performed as a monolayer and multilayer structure. The second option implies reinforcement: five-layer construction, where there is an aluminum gasket between the plastic layers. The thickness of the reinforcing layer is usually varied within 0.1-0.5 mm.

The installation of plastic pipes is somewhat different from metal analogs. In particular, when installing, it is necessary to comply with such conditions:
Polypropylene tubes do not bend at right angles, here tees and fitting compounds are used to change the direction of the highway.
Plastic does not destroy under the influence of temperature differences: the pipe increases in length. Therefore, if the length of the segment of the pipeline exceeds 10 metersThe temperature compensators are necessarily installed.
Under the influence of high temperatures, the pipe is subject to linear expansion, so hard fixation of the pipeline inside wall structures is not allowed: thermal clearances are left.
For hot water, only reinforced products are used that are less susceptible to linear extensions.
An insignificant bending of the pipe is allowed. This can be done heated surface with a construction hairdryer (temperature around 140 degrees).
It should be noted that the storage of plastic pipes on open spaces is not recommended. To protect products from direct sunlight, which destroy the structure, be sure to be equipped.
To buy high-quality pipes that easily work out the manner declared by the manufacturer, it is necessary to follow the selection recommendations:
Selection of component parts.
When mounting, couplings will be required, fittings, wiring tees. The ideal option Combined elements that have threaded inserts or metal frames will be. Such products will provide a high-quality transition between plastic and metal pipes.
Manufacturer.
Products use consistently high demand all over the world, so plastic pipes are produced by domestic, European and Asian companies. The pipes manufactured by German, Czech and Russian companies have proven well. We need to treat the products of Turkish and Chinese manufacturers: Low cost implies low quality.
Marking.
Here you need to pay attention to the bandwidth of pipes, resistance to hydrowards and temperature differences. Optimal option - The selection of the pipe, which according to the characteristics is slightly superior to the desired values.
It should be noted that the durability of the plastic pipeline affects not only the characteristics of the product, but also the correctness of the installation.
Among the companies engaged in the production of polypropylene pipes, such brands are most popular:
Wawin Ecoplastik. Czech company, which managed to conquer a high rating from builders of the whole world. The revolutionary solution of the manufacturer is Fiber entirely flapping pipes that have a minimum weight, but at the same time show high strength and resistance to linear extensions.
FV-Plast. Another Czech company, presented in the market reinforced pipes with perforated aluminum inserts. Released products have a wide dimensional range, ideal for the arrangement of hot and cold water supply.
Pro Aqua.. Russian enterprise engaged in the production of multifunctional polypropylene pipes. The company's products are distinguished by high technical characteristics, while sold in an affordable price range.
In addition, you can pay attention to the products of such companies: Banninger Reiskirchen (Germany) and Valtec (Italy). Plastic pipes of these brands are in a high price segment, but possess practically reference quality.
Polypropylene pipes, widely used for the installation of heating systems, cold and hot water supply, as well as other engineering systems, are presented with a large enough assortment. Different types products have various characteristics and scope. Therefore, choosing pipe products, it is important to understand which pipe from polypropylene is better suited for certain purposes.
To properly select the types and characteristics of PP pipes, you need to pay attention to their marking. First of all, you need to pay attention to the designations that characterize the working pressure and temperature of pipe products. The standardization system current is classified by polypropylene tubes in 4 groups:
When installing heating systems, the question often arises, which pipes are better: polypropylene, metal-plastic or metal. To determine this question, it is important to take into account all the advantages and disadvantages, as well as the characteristics of polypropylene pipes.
The main advantages reinforced pipes Of the polypropylene are their following features:
It is also necessary to consider the disadvantages characteristic of pipes from this material. The main minus for the heating systems is of course the high value of the linear extension coefficient. This can lead to the deformation of pipelines and their output from the mounts, which is often accompanied by depressurization on the nodes of the compounds and causes the occurrence of leaks. In this regard, the use of reinforced PP pipes is recommended, in which the temperature expansion coefficient is significantly lower. However, reinforcement does not eliminate the temperature deformation completely, so the installation technology provides installation at certain intervals of fastening points and compensators.
Another disadvantage is that polypropylene pipes are not exposed to deformation when installing. Therefore, special fittings are necessarily used to perform turns. In addition, when performing installation work and placement of pipelines, it is important to take into account the negative impact of solar radiation, which can cause an accelerated aging of the material.
In general, it can be said that the ratio of the advantages and disadvantages of polypropylene pipes causes their high efficiency when using heating systems, as well as in other engineering networks.
When choosing polypropylene pipes, it is necessary to take into account the four main parameters:
The values \u200b\u200bof these parameters should be correlated with the purpose and conditions of operation of the mounted pipelines.
The maximum operating temperature causes the possibility of using pipes of a certain brand to configure engineering systems of a certain purpose. Thus, PN10 and PN16 pipes can only be used for cold water transportation. PN20 products can be used for hot water systems, and the PN25 pipes are best suited for heating.
For household systems, pipes can be used almost with any operating pressure. However, the value of this parameter is especially combined with a temperature directly determines the life of the products. That is why for operation in the system of heating, it is necessary to choose pipes designed for the highest working pressure.
The diameter of the polypropylene tube determines its throughput, which causes the possibility of applying under certain conditions. For example, a polypropylene tube 32 mm or 40 mm is used to mount the risers. The inner layout is used using a 20 mm polypropylene tube. Also for the same purpose can be used polypropylene pipes 25 mm.
Linear expansion coefficient is an important parameterdetermining the degree of change in the geometry of the product under the influence of high temperature. Depending on this coefficient, the possibility of using pipes for heating or hot water supply, as well as the method of their installation is determined. Thus, PN20 pipes have a higher linear extension coefficient, so they are not allowed to be laid in a private manner. The deformation of the pipe with its heating can lead to the destruction of the plaster. With the opening method, the gasket requires a more frequent installation of fastening elements and compensators. PN25 has a much smaller linear expansion coefficient, which makes it possible to install them both inside the walls and outside.
Depending on the composition of the material, the following types of polypropylene pipes distinguish:
Polypropylene tubes can be produced in four color options: white, gray, black, green. The color depends on the composition and properties of pipe products, which determines the scope of its use.
White and gray pipes are widely used for mounting almost all engineering communications, including heating and water supply systems. The restriction in the use of white pipes is their low frost resistance, which does not allow them to apply them in street conditions.
As for gray pipes, they possess the following advantages:
Black polypropylene pipes are used to install sewage systems and drainage systems. Thanks to the use of special additives, they possess the following features:
Green pipes - the cheapest product type. They are used in private houses and dachas for watering systems.
A special kind is corrugated pipes from polypropylene. They are used to create sewage systems, drainage, storm sewage, drainage. Modern products of this type are calculated on the reception of wastewater with a temperature of up to 60 ° C, and with short-term exposure - up to 100 ° C.
Two-layer corrugated pipes from polypropylene are produced today. They possess the following advantages:
Installation of polypropylene pipes is performed by thermal polyfusion. Its essence in heating connected parts using a special soldering iron to a temperature of about 260 ° C, after which their quick connection is performed.
When performing soldering pipes from polypropylene, it is very important to comply with the technological requirements for heating time, which depends on the following factors:
Heating provides the necessary plasticity of the material that is saved for a few seconds. Therefore, it is very important to quickly fix the connection node, while ensuring correct location Coming parts. It is also important to prevent excessive heating, which can lead to strain pipes.
Optimal heating time when welding polypropylene pipes of different diameters:
The same time is necessary to fix the connection. In violation of this requirement, the deformation of the compound is possible, which will lead to its depressurization.
The Lammin trademark sells polypropylene pipes and fittings from the manufacturer in bulk. We have the opportunity to order a wide range of products of excellent quality, perfectly adapted for durable and reliable operation in heating systems. At the same time, we have favorable prices on.
Polypropylene pipes (PP) among specialists today are considered to be the best pipe products. They have good technical and operational characteristics and differ in their appointment, color, quality and scope of application. They are used for laying, both domestic and outdoor engineering communications.
When choosing polypropylene products, attention primarily draw a marking applied to them. This is explained by the fact that the technical characteristics of different modifications may differ significantly. For example, not any polypropylene tube is suitable for systems operating at high temperatures and elevated pressure.
The current classification of polypropylene products now implies their division into 4 groups. Such types of polypropylene pipes are marked with two Latin Pn letters and two numbers constituting a number that denotes the pressure to which PP pipes are calculated.
Let's figure out which pressure is maintained by polypropylene tubes, and what characteristics have different groups of material.
These values \u200b\u200bare applied to the surface of the products:
It is the properties of polypropylene pipes that make them in demand among developers, both multi-storey buildings and small country households.
Among the positive features of polypropylene products should be noted:
In addition to the advantages of polypropylene pipes have drawbacks:
Since the degree of linear expansion is sufficiently high, when installing the pipeline, it is impossible to allow SP pipes - for this point of attachment on the wall should be located with small intervals.
To make it easier to select these products, you should consider four important points in addition to the product labeling, which was described above:
Products with marking PN20 Specialists are not recommended to be laid by a closed method, because as a result of their deformation in the layer of plastering, cracks will appear. As for the use of PN25 products, it can be mounted in both ways - open and closed.
The open option will not worsen the interior of the room, since the PP tube reinforced well holds the form and it will not be necessary to bend it. Thus, the method of laying a hot water supply system depends on the coefficient of linear expansion of pipe products from polypropylene.
In the world market, PP pipes are presented in the next high.
PPH - Type 1. These products from polypropylene are considered the most simple from the entire range of products manufactured by the modern industry. Their scope of application is a gasket of cold water supply, ventilation systems, industrial pipelines.
PPB - Type 2. This type of pipe polypropylene rolled steel is made from a complex block copolymer. Such products are involved in the arrangement of pressure systems for the supply of cold liquids and heat supply. Also, this product is used in the production of shock connective elements with high strength.
PPR - Type 3. The technical characteristics of the PPR pipe are based on the production of copolymer by rand. Its introduction to industrial production has been world importance. Initially, he had a PPRC abbreviation - a copolymer polypropylene by random, in the future it was reduced to PPR (read: "). From products related to this species, the water supply systems of cold and hot-type are laid. It is this product that will be involved when creating a warm water floor.
Such a molecular structure provided the following characteristics of the PPR pipe:
The technical characteristics of polypropylene PPRC pipes made their alternative to galvanized metal products. Among them are products that are reinforced by aluminum or fiberglass.
PPS - Type 4. The raw material for the release of this product is complexly flammable high-strength polymer. The maximum permissible temperature of the working medium of these PP pipes is 95 degrees. Experts consider them the best option of unarmed single-layer products for heating systems.
Polypropylene tube rental is released in four color solutions.
Description of polypropylene pipes of different colors will help make the optimal choice:
Use this type of pipe products to create engineering communications on drainage and sewerage, as well as structures for disposal of precipitation and groundwater. The maximum permissible temperature of the fluid, which moves along corrugated PP pipes, is for permanent drains + 60 degrees, and for short-term no more than 100 degrees.
Pipelines that build with the use of corrugated products are mounted in open trenches and a trenchless gasket method. Transitions are shut-off using reinforced concrete wells. No additional equipment and special equipment are required for laying a large diameter corrugation.
Now industrial enterprises have mastered the production of two-layer corrugated pipe products from polypropylene.
Their positive qualities are:
Among the disadvantages are exposure to accelerated aging.
In the process of installing the system of pipes made from polypropylene, the thermal polyfusion method is used - the welded parts are heated and quickly connected using a soldering iron.
Some manufacturers equip the tool for welding two, and not one heating element. In this case, the power becomes enough to heat the segments of the pipes of different diameters without any problems.
But this advantage can simultaneously become a disadvantage. The heating is performed at once with two elements capable of overlaying plastic and overload the power supply network. For this reason, the second heater should be used only as a spare when the first fails.
The duration of the heating stage depends on a number of factors:
After heating, polypropylene retains its plasticity for a short period of time. In seconds, it is required to fix the connection, not allowing the appearance of overcasts. The optimal temperature for heating is + 260 degrees.
To ensure a reliable and durable compound, the polypropylene needs to warm up much, but the excessive heating is able to lead to the loss of the shape of the product. Therefore, the time should be controlled during which welding is performed.
Depending on the cross section of PP pipes, it should be:
It is not enough to heat and connect pipes from polypropylene, they should still be able to cool. The period of fixation in time should last as much as the heating phase. If the execution of this process, as a result of the rush, complete earlier, the compound will exploit.
The technology of performing welding PP pipes refers to difficult work. Not only the heating time has great importance, but not compliance with the rules for performing soldering.
The main nuances of the process are as follows:
Most developers, having familiarized themselves with the advantages of polypropylene tubular products, stop the choice on these products. Finance, spent on the purchase of PP pipes, will surely pay off over time.
