What should be noted when heating and bending steel pipes?
Thread Content
It’s a 90° right angle; heating is used for bending, and attention must be paid to the radius as well as any deformation that may occur. Does anyone know exactly how to carry out this process? I had seen it, but I really didn’t pay much attention at the time.

There are requirements regarding deformation, as well as requirements for the radius
The minimum radius shall be not less than three times the diameter
The minimum radius is related to the pipe diameter. Temperature is very important – it should neither be too high nor too low. The bending process should be done slowly. If deformation is a concern, reducing the pipe diameter and filling the pipe with sand before bending can help prevent deformation to some extent
Yes, it’s filled with sand, and the ends are blocked with wooden wedges!
The tube is filled with dry sand; it is possible to manufacture a disc with a radius that matches the required value. Heating must be done slowly and evenly, and bending it also requires slow and even action
Heating should not be applied at just one point; it should be done at multiple points simultaneously； The heating time and the frequency of bending should not be too high ； The force applied to the bent pipe must always be even.
