Pressure relieving devices, ASME and API-ASME codes
Pressure relieving devices, ASME and API-ASME codes
(OP)
While reviewing the requirements for pressure relieving devices for pressure vessels in LPG service, I came across NFPA N° 58-Liquefied Petroleum Gas Code, that in 5.2.1.1 allows tanks under DOT regulations, ASME BPVC Section VIII or API-ASME Code for Unfired Pressure Vessels for Petroleum Liquids and Gases, except for UG-125 through UG-136.
I know that UG-125 through UG-136 are part of BPVC Section VIII, but in the way the exception was written, it may be that API-ASME Code has the same paragraph numbering and the exception applies to this code only. Anybody knows if API-ASME code also has UG-125 through UG-136?

I'm quite familiar with PCC-2. I keep a copy on my desk. The other codes and standards go on my bookshelf.
Instead of a short, cryptic response, could you consider providing a bit more detail as to what part of PCC-2 would help the original poster resolve his issue?

The 1951 API-ASME Code for Unfired Pressure Vessels for Petroleum Liquids and Gases has its pressure relief device requirements in paragraphs W-600 thru W-611.
The 1952 ASME Section VIII has the corresponding paragraphs as UG-125 thru UG-134.
Let me know if you need an earlier edition of the API-ASME Code checked.

I found that this is also consistent to NFPA 59, which has the same wording and tanks exception to the same paragraphs, but mentions only the ASME BPVC.
