Re-stamping of a pressure vessel in response to a MAWP change must be performed in accordance with which guide?

Explanation:
When a pressure vessel’s maximum allowable working pressure (MAWP) is changed, the re-rating and re-stamping must follow NBIC. The National Board Inspection Code provides the approved process for evaluating alterations, performing any required repairs or tests, and updating the vessel’s nameplate data so the new MAWP is legally and safely recognized. This ensures the vessel is compliant with the updated rating and that the stamping reflects the new MAWP and related data. The ASME Boiler Code governs design and fabrication, but not the post-al alteration re-rating and stamping process; API 510 covers in-service inspection and repair, while OSHA 29 CFR 1910 is general safety regulation.
