How to bend profile pipe without pipe bender

The bending of the profile pipe can be performed independently, without the use of expensive and bulky machines. Under all the rules, the work will be no less qualitative. Consider several options that allow you to make flexible pipes with your own hands.

1

Pipe bending with Bulgarian

To perform this procedure, you will need a Bulgarian (angular grinding machine) and welding machine. Go to the work process:

1. Before flexible, it is recommended to fix the pipe (for example, in vice). This will save it in the same plane. If there is a welding seam on the pipe, it is necessary to arrange it on the outside of the bend so that the metal does not break.
2. Calculate the bending radius and mark the bending place. Take the grinder and make transverse cuts along the marker length (from 3 sides). After that you will be able to bend the product without difficulties.
3. The crevices that arise must be fed and clean. Try to do the work slowly and carefully - this will allow you to achieve good quality and not spoil the pipe.

Pipe bending with spring and solder lamp

You will need steel wire with a diameter of 2 mm. Make a spring out of it so that it can go inside the pipe, but not hang out. You can also purchase a finished spring for flexible pipes. Insert it into the pipe, mark the place of bending and heat it with a soldering lamp. After that you can easily bend the pipe using a rounded blank. If the resulting result does not suit you, you will be able to remake the job, but it is preferable to immediately accurately perform all actions.

Pipe bending with sand and gas burner

This method will allow the pipe to give a suitable bending without risk of cracking and flattening. You will need a crystal or purified sand, gas welding (burner), two plugs of wood and drill. Consider the process in order:

1. Instead of quartz sand, you can use the usual. But it must be pre-cleaned. Suck the sand and suck it well, warming up on a fire or burner. Greater sand follows until it stops smoking. When everything is ready, reflect chilled sand into clean capacity.
2. At one end of the profile pipe, we stick a wooden cork (at a depth of no more than 10-20 cm). Fully pour the pipe quartz (or purified) sand and close the cork with the second end. This filling will avoid destruction in the process of bending. If the sand is absent, the material will be easy to deteriorate.
3. In one of the traffic jams, make a small hole. During incandescent, air will be out of it.
4. Mark the place you want to bend, and warm it up with a burner. Then give the pipe the necessary shape. Try not to overload the metal - it can lead to scale formation and loss of material quality.
5. When the pipe will take the necessary shape, remove the wooden tubes and pour sand. It is recommended to heat the ends of the profile pipe - so the plugs are faster than the stretching.

Additional methods bending

There are methods intended for pipes from specific materials that you can also use:

• For bending copper pipe (as well as brass and duralva), water and negative temperature will be needed. One end of the pipe plug the plug, then fill the pipe with water and close the second end. Stop the product to frost and leave it there before ice formation. After that, the product can easily take the desired form. As a filling, you can also use melted paraffin, rosin or lead.
• For the beating of metalplastic pipes, you can use a table salt. Previously, it must be warm up in a pan (until the salt crystals begin to explode) and fall asleep into the pipe. When the hot raw material turns out to be inside, the pipe without great effort will be flexible.

The variety of methods of flexing profile pipes allows you to perform this procedure at home, without resorting to the help of specialists and experts. Try to keep the algorithm for creating bends and act leisurely. In this case, the chances of creating a quality product are greatly rising.
