If you independently perform home work on the installation of water supply networks, then you may encounter the need to flexing the pipe. Since professional equipment in the form of a pipe bending may not be, it is quite difficult to perform. However, there are special methods that without the help of professional equipment will allow flexing pipes from different materials. In our article we will describe several ways to bend the pipe at home.
Let's start with what special tools you can use to flexing pipes from different materials. Usually there is such equipment from professional masters and it belongs to the category of pipe bend. By the flexion method, all pipe bending can be divided into several categories:
By type of drive, such equipment is divided into the following types:
Important: To flexing blanks at home, there will be enough hand-cutting. It is suitable for flexing pipes from aluminum, brass, stainless steel and thin-walled copper with or without plastic coating. The main condition - the diameter of the pipes should not exceed 2.5 cm.
Tip: In the cold season, instead of sand you can use ordinary water. We pour it into the pipe and wait until the water is frozen. After that, we perform bending, we give ice in the workpiece to melt yourself or heating the product.
ATTENTION: Painted or galvanized elements before flexion is better not to heat. Otherwise, you can damage their protective coating.
Usually manufacturers of polypropylene tubes do not recommend bending them at home, but if you are careful, you can do this using one of two ways:
To bend the pipeline from plastic, you need to do the following:
This question is interested in anyone who, by the nature of their activities, is facing the work of plumbing and used various kinds of pipes. If you do not feel about professionals in this area, then you do not have special tools and special equipment for these works. Next, we will give you recommendations, as without special tools, such as tube bending, make a pipe bent home without attracting outsiders.
But what kind of work with the use of pipes you did not perform, there will always be a need for their qualitative and correct collaboration. As a rule, if this work is subject to the fulfillment of the house, then this is done with the help of a special hand device - pipe bending. It is able to bend pipes from aluminum, copper, brass, steel (if the walls are not thick and small diameter). Following the recommendations of specialists in order to bend the water and gas pipes, it is necessary to resort to the hydraulic bending press. Almost all tools, with which you can bend pipes, it is not suiced, so if you have the need to fulfill this work once, there is no need for their acquisition. For this work, you can use classic and less cost methods. In this article we will tell you about the ways of pipe bends without the use of pipe-bending.
To independently bend the pipe you will have to use:
To perform this work, you must follow the following steps.
All these works aimed at flexing various kinds of pipes can be made without additional expensive tools. But with the acquisition of a pipe bender, the same work will be done much faster and better. Pipe benders have various methods Bending and types of drives. Consider various types of pipe bending methods.
Do not be upset if in the process of installing any system in your home ownership and you have a need to bent pipesah, you do not have professional tools, and there was no possibility to purchase ready-made curved pipes at the right angle. All this can be done personally and without leaving home, if you have even the most elementary tools in your arsenal. Let's start.
We grab the design and gradually bend, tightly clamping it. It is necessary to do this with special accuracy so as not to break the item. This process is gradually, slowly moving along the pipe. These actions repeat at six - seven moves. But in the manual bend, you can not have every pipe. For example, a pipe made of aluminum bends easily, but the metal is not very.
Specialists advise. Before proceeding with the fibers of the pipe directly during the behavior of sanitary work, try to do it on some unnecessary segment. Just do not rush, do not make sharp movements. This can lead to the deformation of the pipe either to its breakdown. With your own hands, it is possible to extend the pipes, if their diameter does not exceed twenty millimeters. You can try and slightly larger diameter, but effort and accuracy should be many times more.
As for the metal tube, your assistant should be a gas burner. We act in stages.
It is important to catch the moment of bending. If the pipe is aluminum, then you need to bring a sheet of paper to it. If it turns around or get silent, you can start. If the pipe is made of another metal, then the section will serve as a blust in the process of heating. The heat treatment method cannot be applied with galvanized pipes. High temperature will damage and lead the coating. It is necessary to know that if we are talking about the bending of the square pipe, then without a powerful soldering lamp or the burner you can not do. And most importantly, at the very beginning of the work, such a product is heated from all sides.
If you apply the above fillers, you can curle both promotional and aluminum segments of solid diameter. Step-by-step instruction.
At this method, the sand serves as a protection that prevents the deformation of the pipe and the non-uniformity of bend.
It should be borne in mind that:
Water operation occurs in the same way. Pour water inside the pipe, close the plugs. Water is cooled to the freezing stage (in winter in the frost or in the refrigerator at any time of the year). When the liquid freezes, neatly, without sharp movements, bend the pipe.
The manual method of flexing pipes can lead to their breakdown or unnecessary deformation. Therefore, it is recommended to use special equipment or other materials to carry out such a type of work, which will accelerate and facilitate the flexing process.
Bend the pipe from the metal is much easier through the use of pipe bend. This specialized equipment is a few species.
If you have not bought pipe bending, and you need to bend the pipe, then use a plate that has a view of a curved blank with a groove. It can be used if you need to bend the pipe from metal plastic or metal with a diameter to 45 mm. The pipe is inserted into a special clamp on the plate, clamping and bend along the plate along the groove. This method refers to the category of primitive, but reliable. It is successful if the pipes have a small length.
Such a "instrument" is used if you need to bend a pipe made of non-ferrous metals. They differ softness and flexibility that during the flexion process can lead to damage. In order to avoid negative results and the mid-end springs of this diameter are used, which makes it possible to place this spring inside the pipe. When the spring reaches the location of the alleged bend, you can curb the pipe on your knee, or secure it with the help of vice. When using such a spring, the pipe wall can be easily bend, avoiding deformation and damage. After the end of the process is completed from the pipe by means of a durable cord attached to it.
The question of how to bend a profile pipe without using special equipment for this, many of those who are going to build on their panstone Greenhouse. Such structures made of bent pipes not only pass significantly more light, but also differ in high stability and durability, if you compare them with structures from wooden bars. It seems that the proftrubube, creating an arched structure, is not easy, but if you understand the features of this process, it is quite possible to effectively perform it using the simplest devices.
The essence of the flexible metal rolled, regardless of the form of its profile, is that the profile pipes are given partial or full bend. Perform such a technological operation in two ways: acting on the bent pipe only with pressure or additionally heating the pipe of the pipe, in which the bend is performed. In the course of bending, two forces are simultaneously operating on the metal pipe:
It is the impact of such multidirectional forces that causes complexity characteristic of the process of flexing any profile pipes.
If you do not take into account the subtleties of this technological process, instead of bending the profile tube, you can simply minimize the product, irrevocably spoiling it.
So that this does not happen, it is necessary to take into account not only the characteristics of the material of the pipe, but also its geometrical parameters are the size of the section, the wall thickness, the radius to which the bend must be performed. The knowledge of the listed will allow you to choose the appropriate technology and bend the proftrube correctly, without resolving it and without receiving a corrugated surface.
Categories of the profile pipeline include products having a different cross-sectional shape - round, square, oval or flat. Despite such a variety, for the construction of a greenhouse or a canopy mainly use rectangular or. This is due to the fact that on their flat walls is much easier to mount the external coating.
The range of modern profile pipes is characterized by a large variety. Their geometric parameters, the main of which are the cross-sectional area and the wall thickness, determine the plastic capabilities of the product. The latter characterizes such an indicator as the minimum allowable radius of rounding. It is this parameter that allows you to determine which the minimum radius can be bent a professional to be bent so that it is not damaged.
To determine such a pipe parameter with or a rectangular profile, as a minimal bending radius, it is enough to know the height of its profile. If you are going to bend a profile tube with cross section In the form of a rectangle or square, follow the following recommendations.
Such recommendations will be useful to those who are going to bend profile pipes in order to make racks, canopies and various frame structures from them. At the same time, however, it should be borne in mind that the possibility of high-quality flexion of pipes affects the thickness of their wall. Products, the wall thickness of which is less than 2 mm, it is better not to bend at all, and if it is necessary to create structures from them to use welded connections.
At home, bend proftrube, which are made of carbon or low-alloy steels, can only be taken into account certain nuances. Such pipes after bending can sink and return to its original state, so the finished structures must be re-customized by the template. The magnitude of the skip characterizes such a parameter of profile pipes, as the plastic torque of resistance - WP. This parameter is indicated in the accompanying documentation (than it is lower, the less promotion profits in the process of their bending).
In production or homework, proftrube is bent both heating and cold condition. Heating, which is produced using a gas burner, significantly increases the plasticity of the metal, due to which less effort is required for bending. Pipes of a small section can be bent and without heating, because they are so different with a good plasticity.
Regulatory recommendations regarding the use of heating are available only for products. round cross section. So, heated before flexible it is recommended that the pipe diameter is greater than 10 cm. In cases where it is necessary to bend square or rectangular pipes, It is worth it for your own experience or tips of other home masters.
If at your disposal there is a pipe bender, with it, you can easily handle the task of cold flexible pipes, the height of the profile of which is in the interval of 10-40 mm. In the absence of such a device, it is necessary to solve the question of how to bend the pipe without a pipe-bender, after conducting uncomplicated tests. They will help you determine, you should heat the proftrub before flexible or not. These tests are carried out as follows. One end of the pipe is clamped into vice, and the second is put on a pipe with a large size of the internal cross section. If with the help of such a shoulder, it is possible to bend the pipe clamped into vice, you can perform this process without preheating.
Flexible pipes on various methods well demonstrates training video, but it will not be superfluous to pre-examine this process in all details.
To bring the profile pipe with your own hands with a hot method, you must first fill it with sand. This will make the bend better and uniform. Because you have to deal with hot metal, all work should be performed in dense tarpaulin mittens. Bending itself, with the implementation of which can be found in the video, is performed in the following sequence.
This method, which is easy to implement at home, is best used in cases where at the prom Profiter it is necessary to form a single angular bending. Multiple metal heating can lead to loss of its strength, and it is impossible to avoid it if you jet the pipe for its use as an element of arched design.
Bend the profile pipe itself, without heating it before, you can, as with a filler, and without it. Do not require filling with sand or rosin pipes, the height of the profile of which does not exceed 10 mm.
There is another technique that involves the use of a sprocket with a dense navill of turns instead of the filler, which is inserted into the inner cavity of the prom and protects the walls of the product from the deformation, as well as from the excessive change in their thickness in the process of bending.
Those who need to bend profile pipes with their own hands, not previously heating them, you can use the learning video and the following simple recommendations.
The question of how to bend the pipe without a pipe-bender will not cause difficulties if used to perform this operation the simplest devices. You can perform cold flexible pipes using the following devices.
Option what is called skouring hand. The long lever of this is extremely uncomplicated device allows you to cope with rather thick pipes.
For forming on steel or aluminum promotional curvators, motionless rounded patterns are used on a large radius of curvature, which mount special clamps for fixing the product. On such an adaptation, the pipe is also hung manually, with an effort to lay it in the chamber of the template, the form of which exactly corresponds to the desired bend radius.
Plywood and metal brackets are everything you need for the manufacture of a bending template
To effectively bend steel or aluminum pipes At home, you can make an upgraded bending plate using the following guidelines.
At that moment, when you do not use such upgraded pipe bending, its pedestal can be adapted to perform various plumbing operations.
For bending at home, profile pipe products, the height of the walls of which does not exceed 25 mm, you can make a special mandrel. To this end, it is better to use an overall workbench, on the surface of which there will be enough space for such a device. To select the optimal location of the element that locks the flexible pipe, often spaced openings are performed at one end of the workbench. For providing the desired bending radius, proftrub is answered by a special pattern that can be made of thick plywood or metal corner if you are going to use it often.
Of course, if you have a significant amount of work on flexible profile pipes, it is better to make a special machine for this, whose drawings are easy to find on the Internet. We will not take here to disassemble this question, since more than in detail is considered in the articles on the links below.
Do not do without such a machine and in the event that you need to bend pipes with a large cross section of the profile. The main working bodies of such a machine, distinguished by broad versatility, are three rolls, two of which are fixed motionless, and due to changes in the position of the third regulate the radius of the product bending. A chain transmission and handle that the operator rotates as a drive of such a device.
During the most different plumbing work, a question may arise, and how to bend a pipe at home - if there is no specialized equipment at hand? Of course, it would be nice to have a special pipe bender. But far from everyone is available. Nevertheless, the outputs from the problem situation are still available.
And the approach in this case will be your own, special.
When installing the pipeline in his house, you have to be bending the metal pipes, which is not so simple without certain skills and special tools.
Pipes made of metal, at any stage of bending can be broken or decreased in the diameter in the location of the inflection. This kind of deformation is extremely undesirable, since in this case the seraning in the place of bending increases. In order to avoid this, you can recommend before flexing to fill the pipe with dry sand, or dry sawdust. You can also drive special choppers from wood into the pipe. But with the condition that they can then be quickly removed without deforming the pipe.
After these procedures have been done, you can proceed to the camp of the pipe. If the metal alloy is soft enough, then you can apply another pipe as a lever, carefully forming bending in the right place. By the way, in winter it is possible to use conventional water instead of sand. It will be necessary to fill it and wait until it turns into ice. Accordingly, after flexion, the ice will need to melt - and just merge from the pipe.
In the same case, if the case has to have with aluminum pipes or steel, you will need a soldering lamp or gas burner. Here you will also need to first fill the pipe with sand or sawdust, and then fasten the end of the pipe in the vice, or in some other way. Then the place of bend must be evenly warm up to the moment until the pipe is bright red. Bending such a pipe can also be hand. Of course, not forgetting to put on gloves to avoid burns.
When the metal pipe is bent, sand and plugs are used, which are put on both sides of the pipe. It is necessary in order not to damage the tube, because it easily can spoil or even break.
If we are talking about a pipe with a square profile, it can be bend it even without the need to preheat. But it will be necessary to fill with water in winter or refueling sand. In order to bend such a pipe, a special rubber cynica will be required - a hammer. The pipe is installed in two ends on some support - and the bend is formed the desired degree. If the angle of bending turned out to be too large, then the pipe made of steel can be heated - and correct the situation.
Note! The profile tube can be bent without a special device. To do this, in the place of bending inside the pipe will need to shove the spring - and only bend the pipe. In order to then do not occur with the extraction of the spring, you can pre-bind a cord or rope to it - and then just pull it for it - the spring is easily removed outside.
The need for bending may occur, for example, if the so-called warm floor is arranged. Numerous bends in this case will help much more efficiently use the potential of the heat-conducting surface of the pipe. At the same time, several ways can be offered:
To bend exactly and correctly, you will need to do the following:
Some are confused with plastic. However, this is rooted incorrectly. Plastic and polypropylene are completely different chemical elements, and the properties of pipes made of them are also completely different.
Generally speaking, polypropylene pipes at home is not recommended to bend. But if there is no way out, you can offer at least two ways to do it.
The first assumes to preheat with the help of a special construction (not everyday!) Hair dryer of the pipe is about 150 degrees. Then you can be folded with your hands - again, not forgetting about protective gloves. It is necessary that the following condition is satisfied: the pipe wall, where the thickening is observed, should always be placed on the outside of the bending angle. When the bend was carried out, it will be necessary to carefully examine the pipe for the formation of all kinds of defects.
The flexion of polypropylene pipes is carried out using a special construction dryer.
You can also bend polypropylene tube And without the need to preheat it. But at the same time, the radius of the deflection should not exceed the eight diameters of the pipe.
As shown, it is possible to bend almost any pipe without the need to use specialized devices. However, it is preferable to use them. After all, everything is constructively in the pipe bending, so that the process goes as smoothly and fragile.
In this regard, it is possible to pay a little attention to these devices.
Generally speaking, pipe bending can be divided into many species and subspecies. But the classification according to the method of flexion and the type of drive, which is used in them, is considered to be the generally accepted.
So, according to the method of flexing the pipe bending, it is customary to divide on:
In addition, pipe bending can be divided by the type of actuators in them:
Handheld tubing is a device for the use of the house, in the garage, in the car service and other places where the flexible has to be carried out rarely and with low accuracy.
If you need to make bending of the pipe at home, then you can recommend to purchase not too expensive manual pipe bending. As practice shows, in the overwhelming majority of cases it is quite enough. He can cope with copper thin-walled pipes, made of plastic, aluminum, brass - with a diameter of no more than 2.5 centimeters.
Nikolai Sergeevich Stepanov, Master Plumbing:
If you have to deal with galvanized pipes, you need to remember that it is categorically not recommended to expose them.
Pavel Romanovich Gushchin, Master Installer:
Even after the pipe was, it would seem, successfully bent, it is necessary to thoroughly examine it and control tightness, for example, simply by passing water through it.
Summing up the said, we can safely say that it is possible to carry out a high-quality fold of the pipe at home all the same. However, if there are doubts that everything will turn out to do with your own hands - it is better to ask for help to professionals.
Repair of dwellings, in particular repair of a private house, often requires the use of pipes, and not always perfectly even. In such a situation, the question arises: how to bend a pipe without a pipe bender at home? If you know all the tricks of this process, then it is quite simple to do it.
Metal - the material is quite durable, but with special impact it is quite easy to bend. Today, there are several methods for flexing the metal pipe with their own hands.
This type of metal structures is often used to build greenhouses of various sizes and destinations, as well as arbors and other buildings on the site. The main feature of the building materials of this pipeline is that when flexing it is very easy to damage, for example, it can easily flatten or crack. The exit from this situation is pretty simple. Its cavity must be filled with dry small sand or water (in the future, water needs to freeze). It is these actions that will exclude the possibility of damage to the pipe and achieve the desired result. The same reception is suitable for duralumin, and for brass pipeline.
If there is a square pipe with a small cross section in your hands, it can be easily bent and without heating. However, filling the cavity of sand or water is still preferably. In contrast to the usual round blanks You will need a rubber cusion.
The pipeline itself is required to put on two reliable supports. After that, using a reference to the Cyonya, to make the bending of the product, and you need to make all actions very smoothly and carefully to avoid possible damage. If you need to achieve a sufficiently large angle of curvature, to facilitate the process, the material can be heated at the location of the expected bend.
Exactly metal plastic trumpet Most often used to arrange a warm floor system. To ensure the efficiency of the system, it is necessary to provide parallel operation of the pipeline with the heating system.
Features of laying of warm sex imply the presence of a large number of folds. However, there are no available ones. It is necessary to make bends yourself, and for this you need to know all the secrets of the material and procedures.
Also, as in the case of a metal blank, there are several ways to obtain the necessary coast:
There are such situations when you just vital to bend precisely the polypropylene tube. However, manufacturers' opinions converge in one: to do this is undesirable. But if without it it does not do without it, use one of the two possible methods.
Main methods for bending polypropylene material:
Instruction that will help you enough to bend PVC pipeThis includes several items, performing which, you, without assistance at home and plastic pipeline, give the right shape. So, to work with PVC pipe, you need to perform the following actions:
The perfect bend of pipes, regardless of its material at home, is quite difficult to achieve. However, if you carefully study the theory and hold not one experiment on unnecessary areas of such a pipe, you will practice clearly, how to bend the pipe without a pipe bender and can do it at any time convenient for you. Be sure to use our advice to make work as correct as possible and without big losses.
