Closure welds in B31.12 Hydrogen Piping

Closure welds in B31.12 Hydrogen Piping

I know there is a stipulation about a closure weld or weld that can be 100% X-rayed in lieu of hydrotesting in B31.3 process piping; however, is there any similar stipulation for a closure weld in B31.12 hydrogen piping?

RE: Closure welds in B31.12 Hydrogen Piping

That’s quite an easy question to verify if you have a copy of B31.12. I was able to pinpoint the answer within a minute.
I’d be happy to help you but what have you tried so far to find out? Was there anything within B31.12 holding you back, perhaps understand/reading the table of contents?
B31.12 has been edities/formatted in a very similar manner as B31.3, so if you arrange to ‘read’ B31.3, this is an easy exercise.

I looked at B31.12 in the hydrotest section, however, I did not see anything in this regard. I will go back and look more thoroughly. Please reference the section if you have it.

XL83NL, Sorry I went back and looked in B31.12 and found it in 30 seconds. Thanks for you reply.
