ASME PCC-1 BOLTED FLANGE ASSEMBLY PROCEDURE
- Thread starter rickylee
- Start date
Read the forward of the document. PCC = Post Construction Committee.
This is the first document from a group that has been working to establish ASME standards for post-construction (i.e. after original fabrication) repair, alteration, and rerating of pressure vessels & piping after they have been placed in service. Yes, I know that API-510 and NBIC cover some of this. The PCC is working on a very comprehensive document that covers all types of issues that API-510/NBIC don't cover as well as to provide guidance on design, welding, PWHT, and testing details for conventional welded repairs. As I understand it, once the PCC repair/alteration/rerating standard is issued API-501 and NBIC will refer to the PCC document and the equivalent sections in these 2 standards will go away.
