Forming strain head formed from pipe
Forming strain head formed from pipe
(OP)
Hi, I'm trying to find out the forming strain according to equations of table UG-79-1, ASME VIII div.1 Ed.'15.
Case: hemispherical head formed from pipe (A 333 Gr.6).
What are Rf and R0? I mean, Rf=R final sphere, but R0? At the beginning I have a pipe, not a plate, so it's not equal to infinite, isn't it? Thank you

I admit I cannot understand how you plan to fabricate a head from pipe, let alone why.

The problem with sloppy work is that the supply FAR EXCEEDS the demand

My problem is: what is the forming strain of the final head? I need to know it in order to decide if doing a post forming heat treatment or not, according to what ASME requires.
