    post pwht weld repair on SA-387-11 per section VIII -1

    Yeah, that is what I found. I searched every spec concerning repair and PWHT under different P groups and could only find allowance for pipe and tubing 4" and less with wall thickness of .625 for P4 material. I figured I'd ask to see if I missed something. Thanks.

    Under any condition is it permissible to make a repair to a sa-387-11 weld after PWHT and not have to re-PWHT per code.
