How to bend a pipe without a pipe bender

Nowadays pipes are used in many professional fields. They are used in construction, manufacturing, mechanical engineering and even in agriculture. In the process of performing various tasks on the arrangement of the house and the area near it, too, can not do without pipes. To shape the pipes, they should be bent. But how to do that? In the article you will learn how to bend a pipe without a pipe bender (for example, for a canopy). We suggest that you familiarize yourself with simple, but effective methods of bending the shaped pipes at home.

Methods

Flexion tube is carried out in various ways. Some men, strong in their hands, even do it with small-diameter pipes by hand. However, this technique is unreliable - the risk of pipe breakage is high. In view of this, it is better to use available materials or special equipment for these purposes, which, among other things, will facilitate bending at times.

Plane parallel plate

If you really need to bend the pipe, and the purchase of special equipment in this situation is unprofitable, then for this you can use a curved plate with a groove. It can bend metal / metal-plastic pipes with a diameter of 45 mm.

In order to bend the pipe, it must be inserted into a special clamp on the plate, then clamped and bent along the groove. This technique is rather primitive, but as practice shows, it is quite effective.

Only short pipes can be bent on a plane-parallel plate.

The diagram above shows a simple plane-parallel plate, where at number 1 the plate is marked, at number 2 - the plate, respectively, 3 is the clamp, and 4 is the pipe to be bent. Such a device is quite possible to make yourself.

Steel spring

Pipes from soft non-ferrous metals are thin-walled, so this is a rather malleable material. This explains the fact that bending pipes from it often leads to damage to them. In order to avoid this trouble, when bending a pipe from non-ferrous metals, a steel spring is used that has an average stiffness.

The diameter of such a spring should be slightly less than the internal diameter of the pipe. This is due to the fact that it will need to enter into the pipe to the place of the bend. After that, the pipe can be bent, for example, on the knee or having previously secured it in a vice. The steel spring holds the walls of the pipe from non-ferrous metal, preventing them from flattening.

Before you insert the spring inside the pipe, you need to securely attach a long strong wire. Due to this, you can remove the spring from the pipe after completing its bending.

One of the popular methods is to make a bending device. To do this, a small pipe of a larger diameter must be welded to a long pipe of a smaller diameter. Thus, the tube to be bent is put on the fixture and its formation is carried out at the right angle.

Profile tube

Before proceeding to the bending of the profile pipe, it would be nice to get acquainted with its characteristics, starting from which you can choose the method of its bending.

You can learn about the characteristics of the profile pipes, as well as the methods of its bending, from the article “Methods of bending the profile pipe”.

Bulgarian and welding

One of the methods of pipe bending involves the use of welding and grinders. Bending of pipes in this case is performed in the following sequence:

• The first step is to calculate the radius of the pipe.
• Along the length of the section to be bent, uniform transverse cuts are performed.
• Then the pipe can be bent without any effort.
• Propane seats should be welded.
• Then the bend should be processed by grinding the weld.

This method allows you to bend the pipe at the desired angle.
