Here's an odd one.
One of our many suppliers fabricated some pump skids for us. During the course of our independent inspection on receipt it was noted that the weld caps hadn't been ground flush for UT. When we really started getting into it, it turns out there was also a bunch of 21.07 mm thick P1 piping that also wasn't PWHT. Vendor / supplier claims they were fabricating to ASME V111, Div. 1 (which would have provided an "out") but the calculations and design are for B31.3 High Pressure piping.
Oh yeah, these pumps have already been installed offshore.... :(
So, here's the question; we ARE going to do a PWHT on all the welds that require PWHT and we ARE going to do RT AFTER PWHT....
Now, opinions please ~ Is there a need to re-perform Hydrotesting?
