Hello i am working in fort mcmurray canada, i can not find anywhere in b31.3 where the RT of a PWHT wet sour service has a requirement of waiting 24 hrs after pwht for a rt to take place. So is there that requirement in any other code? the client is pushing hard to perform the rt right after the welding is done.

Can’t think of a code that would stipulate such a commercially contentious requirement off hand. It is usually contained in end user specifications.
