Thread: elongation when bending pipes

When designing sheet metal bends I just type in K value into the program and flatten the 3d model to get the final flat design. I imagine elongation also occurs when bending round pipes. I found very little written on the topic on the web or perhaps my search keywords are just not the right ones. Are you guys aware of any resource/book/article to help me gain more insight into calculating elongation for pipes?

Thank you for stopping by. The equation listed calculates the real bending point, but it requires elongation length in the first place. I think some additional info is needed.

Pipe bending varies quite a bit, depending on the pipe, being LIGHT WALL, MED, HEAVY, ETC., even the coating can vary the parameters slightly.
You can get close to within a few millimetres, but that could vary on the next piece of pipe. The position of the seam in the bender can alter the measurements too. DAMHIKT
