Relationship between pipe wall thickness and minimum bending radius of pipe
Thread Content
If the outer diameter of a metal pipe is determined, what is the relationship between the wall thickness of the pipe and the minimum bending radius of the pipe? Is there an optimal value for the wall thickness or does it change monotonically? Please give some advice from experienced experts.
Look at the mechanical properties of the material, right? Generally, elbows have a radius of 1 times or 1.5 times. If you choose a radius of 0.5 times, or 0 (at a right angle), then the pipeline wall thickness reduction rate and ellipticity will not meet the requirements.

The specific relationship is unclear: If it is too thin, the stretched side will break before the size is reached and there is no material left. ； If it is too thick, it compresses the side. Before the size is reached, it has been stacked out of shape and has various wrinkles. @boyirensheng
I seem to understand. It has something to do with the material, bending method, and the degree of deformation allowed for the bend. Thank you.
There are also related to cold bending and hot bending processes.
