Pressure Vessel Designation
Pressure Vessel Designation
(OP)
Hello, I'm trying to figure out as to why our main condenser and our dump condenser would have no designation as a pressure vessel as per PA inspection requirements. They're still vessels that CAN encounter pressure and they have an NBIC number accompanied by shell MAWP ratings in psig.





RE: Pressure Vessel Designation
Second, per ASME Sec VIII, Div 1, vessels can be exempted based on size and service. See U-1(c)(2), and especially U-1(c)(2)(f).
Are your condensers stamped? Could be they were NBIC registered even if not stamped.
Regards,
Mike

ASME VIII requires devices to be code stamped only when the MAWP is 15 psig or greater.
Your condensers probably have a MAWP that is much less...
Have you made a call to the original fabricator ?
