I am hoping yall can offer some clarity for me. I have a U stamped pressure vessel with a manway on the bottom head that has a nozzle welded to its cover (added for contect). The nozzle is 2" too short. If we cut and weld a new nozzle onto the manway, will that require a R-stamp? There is a differing of opinion at my site. Some people say the code only extends to the manway itself and not the nozzle. I believe the nozzle is part of the manway and therefore covered by U-1(e)(3) and therefore needs an R-stamp for the repair. If it does need an R-stamp do you think it would be acceptable to use 100% x-ray instead of hydrotesting the entire vessel?
