Nozzle Repair
(OP)
I have a pressure vessel that has corrosion damage on the sealing face. The flange face damage is not severe enough to warrant a replavement flange, we are planning on welding ou the corrosion damage and machining the face,
The fabrication company have provided a weld procedure for V butt welds for welding new flanges to the nozzles, nozzle is A105 GrB & flange is A105N. Will this procedure cover weld repairs to the flange face?

You can consider local weld repair to the flange face using the above. However, you need to peen the edges of the damaged area before welding to avoid having undercut around the perimeter of the repair area after welding.

Please obtain a copy of the National Board Inspection Code (NB-23). The National Board deals with nameplate registration requirements for pressure retaining items, and what is required for Repair and Alteration activities, including stamping requirements.
