Welding Repairs to a Pressure Vessel
Welding Repairs to a Pressure Vessel
(OP)
I am looking what the rules and regulations are with regards to performing welding repairs to a pressure vessel. Is this outlined in a ASME code and if so...which code? What are the rules and regulations with regards to hydrotesting? Again....is this outlined in an ASME code and which one. I was searching ASME's web site and could not find which code I needed.

Also, talk with your Authorized Inspector

The work must be performed by a "R" stamp holder.
Contact your insurance carrier and/or the local jurisdiction. Who ever issues the certificate.

A parenthetical comment: If you don't know how to repair a pressure vessel before reading the NBIC, you will not know how to repair it after reading the NBIC.

The NBIC is the place to look for repairs to pressure vessels. In regards to pressure testing/hydro testing, NBIC RC-2050 requires that the integrity of the repair shall be verified by examination or test and the examination and test be used shall be subject to the acceptance of the inspector(AI) and where required, acceptance of the jurisdiction. Take a look at NBIC interpretation 98-33, you may be able to use examination (NDE) in place of hydro testing.
