Applying the NB Mark for Section I replacement parts
Applying the NB Mark for Section I replacement parts
(OP)
Newbie question:
When supplying Section I replacement parts where the P4 indicates the NB number, is the manufacturer required to stamp the original NB number and NB mark onto the part?

This would apply to headers, tube panels with headers, etc.
When would you have to stamp the NB number onto the component, other than for OEM? Would there be a difference if we were supplying parts for an alteration vs an inkind replacement component?
RE: Applying the NB Mark for Section I replacement parts
Per the NBIC, if these components are being installed as a repair for the pressure retaining item, the only stamping that is required would be a repair nameplate. I don't see any requirement for stmaping the item unless the Inspector and Owner-User prefer to have the item stamped versus a nameplate.

I realize that the adoption of NBIC varies depending on the jurisdiction, however I'm hoping there are some clear guidelines if the original boiler was registered with the NBIC.
I've reviewed the NBIC site without success. They provide some info, however I believe it applies to OEM registration.
btw, this forum is a great resource. I'll definitely try to contribute in the future.

In the 2004 Edition/2006 Addendum of the NBIC refer the AI to the following
Mandatory Appendix 2 Stamping and Nameplate information
2-1000 Scope
Stamping a nameplate OR the item is permitted. I would recommend you insist on a repair nameplate. I never like to stamp items even using low stress stamps.
RE: Applying the NB Mark for Section I replacement parts
After dissecting Section I and consulting with our AI, we did not register the "parts" with the NB. If we had EACH SPOOL WOULD HAVE BEEN REQUIRED TO HAVE IT'S OWN NB# STAMPED ON IT.
We DID mark each spool per PG-106.8.1 and 106.8.2 (Stamped if >5" O.D. Stenciled if </= 5" O.D.) and gave each an in-house S/N for MTR/WELD tracability. PG-106.8.2 says markings only have to remain legible until parts are installed.
We supplied the P-4's to the customer so that the erector may register the repair with the NB.
