ASME B16.5 CL600 Flange Rating
ASME B16.5 CL600 Flange Rating
(OP)
The three of us got stumped yesterday on this matter and we've been investigating when we can. i was not successful with search in this forum even though i believe it has been asked before.
Essential criteria:
Piping Code, ASME B31.8
ASME B16.5 12-inch, RFWN Std Flange, A105 Material
30° - 200°F Temp Range
Piping MAOP = 1050-psig
Pipe Material, 12-inch, X52, 0.375wt
ASME B16.5 Group 1.1 lists this flange rating at 1480-psi. Although the flange thickness at weld does not meet the P=2StFET/D in B31.8 for an Class 4 location (compressor station). So, we think a higher strength flange material is needed per MSS SP-44.
ASME B16.5, paragraph 2.7 (I think as i do not have reference with me) states something about Bmax. Please clarify where/when this applies.
Can this flange be utilized and comply with applicable codes? I'm requesting clarification/direction with references in B16.5, MSS SP-44, or otherwise.
thanks!
