Montimia new system Heating, changing batteries or re-engaged in a sealing of threaded compounds in the heating system before the start of the heating season, pay a couple of minutes of its attention to what materials the specialist will use in its work and how it takes it, for example, a pipe leading to the heating system of your home. Why is it important?
If you are ready for all these risks, it is possible to use flax, paint and. However, the use of FMU ribbon or flax has long replaced the safer, reliable and durable methods of sealing mounting assemblies and heating pipe systems. These are modern threaded sealants - anaerobic gels and polymer threads that are well suited for the home heating system and not only.
If you have to be mounted in the near future or to repair the heating system, it is better to choose modern sealants, which are several times easier to use and economical, but even more traditional sealing materials are reliable.

When building a private house, first of all, it is necessary to take care of the high-quality system of heating and insulation of the house. It is no secret that in any heating system, the pipes play one of the main roles. In the recent past, widely used steel tubes For heating, however, their use was associated with some difficulties, namely with the formation of corrosion on the walls of the pipes.
Steel pipes with chopped carvings.
With the advent of new materials, such as, the pipes from steel began to go to the background. However, thanks to galvanizing, modern technologies Could "defeat" corrosion and steel pipes again occupied a worthy place among heating pipes.
As you know, any heating pipes have pluses and minuses, today simply does not exist. perfect option For all occasions, the exception may be. They have many advantages, among which durability, the ability to withstand high temperatures and many other advantages. Therefore, many specialists call copper pipes The best for heating systems, but even they are not devoid of disadvantages, such as high cost.
Consider the advantages and disadvantages of steel heating pipes.

At the construction site, preparation of the installation of the heating system.
There are 2 methods of galvanizing steel heating pipes:
Note! The cost of galvanized steel is higher than the cost of metal plastic, polypropylene and black steel.
To somehow prevent the appearance of corrosion, pipes without galvanized before installation should be covered with special paint.
There are several ways to connect steel heating pipes. Each of them has its pros and cons who need to remember when installing the heating system. Only compliance technological process It will avoid unpleasant surprises in the heating season.

Methods for connecting steel pipes for heating:
Gas welding. Mainly applied to connect thin-walled pipes. As a result of gas welding works, a reliable, durable connection is obtained. Often used in close space when the use of other methods of compound is physically impossible;
Electric welding. Most often used for welding pipelines with thick walls (main heat seafood). Electric welding allows you to heat the entire thickness of the pipe, which is difficult to achieve a gas welding;
Threaded connection. Exercised using special threaded fittings. In addition, you must independently cut the thread on the pipe, which increases the installation time of the system.
Important! Galvanized pipes can be mounted only with the help of threaded connections, the use of welding is extremely not desirable. The fact is that in the process of welding, under the influence of high temperatures, the zinc coating is simply burning. Zinc is not able to withstand the temperature of over 900 ° C.
Thanks to a variety of fittings, branches are performed, turns, transitions from one diameter to another, etc. Collapsible compounds allow repair and maintenance of the pipeline.
A variety of fittings allows you to perform any heating system.
In order to connect the heating pipes are used various methods and materials. The method of connecting these building elements between itself directly depends on what kind of raw materials such pipes were made. The most frequently used pipelines are pipes from polypropylene, steel, metalplastic and copper.
In this article we will tell about which methods are most often used by installers when installing the types of heating elements listed above.
If there is a challenge to equip heating with plastic pipes of small diameter (up to 63 mm), in practice there are two ways to connect such pipes:
In the case of docking pipes with a large diameter (from 63 mm), the use of docking welding is resorted to the use of docking welding. This installation method does not require additional connecting elements, maintaining an excellent degree of pipe fixation. You can also apply and suitable fittings (coupling welding). If there are pipes with a diameter of 40 mm, it is more convenient to apply manual welding, but the larger elements are taken to docile with a special device that pre-centering.
Immediately before installing heating system It is necessary to thoroughly think over the entire process of assembling the pipeline. This will avoid at the time of work of unwanted nuances that affect the final quality of the assembly of the heating system.
Here we denote the main nuances of how to connect plastic pipes Heating:
After complete cooling, the connected details are ready to use.
Metal-plastic elements and PEX pipes are often docked using the same method. Here we describe in detail the technology of mounting the heat pipe from the above materials.
Sometimes when installing communication systems, it is necessary to combine elements made from different materials. Especially often in construction practice there is a connection of plastic pipes with metal, to execute which one can take advantage of different ways.
We will tell how to connect with the maximum reliability. plastic site Pipeline to an existing steel or cast iron system. We have described in detail technologies that allow us to ensure tightness when docked. The article provides devices and tools necessary for work.
Usually, when laying water, sewer or other systems, builders are trying to apply the same material. However, in some cases, do not do without combined designs. Most frequent reasons Serve as follows.
Planned replacement and urgent repair work . Cast-iron communications that are equipped with houses built several decades ago, gradually fail. Over time, metal elements are subject to corrosion or clogged, because of which they need their planned or emergency replacement.
It is quite natural that in this case the old cast iron or steel pipes are replaced with polymer, which differ less than the cost and ease of installation.
In old houses with long-established communications to metallic (usually cast-iron) risers, modern polymer pipes are often connected.
Building. The process of individual or public construction of houses is associated with gasket of heating, sewage, water supply liner. Often mounting various systems Different organizations are engaged, due to the inconsistent work of which several types of pipes are supplied to the construction site - both from metal and plastic.
Special cases. In some situations, combining heterogeneous materials is an urgent need, for example:
As we see, the need for combined different species Pipes arise quite often.
