F51 deform during pressure test

F51 deform during pressure test

(OP)
Any reason why material F51 can deform during pressure test at 250 bar. From the report the heat treatment looks perfect.
This is first time we found this issue, before this no problem.

RE: F51 deform during pressure test

Please reread your post and then imagine you cannot see your vessel and you know absolutely nothing about it, than ask yourself from your post how we who know nothing about your vessel can possibly give you an answer.

Sure, very simply, the applied stresses exceeded the yield strength of the material.

RE: F51 deform during pressure test

A star for both desertfox & metengr. How about adding possibly a poor design?

+1 for stanweld.

RE: F51 deform during pressure test

Quite surprising, 250 bar is a piddly amount of pressure.

RE: F51 deform during pressure test

3626 psi isn't piddling where I come from. It's a substancial working hydraulic pressure.

RE: F51 deform during pressure test

How much applied stress does this 250 bar internal pressure translate to in the pressure vessel? Is it above the F51 yield strength?
