Hope things are fine at your end.
Sir I have one query on using flanged forged material ASTM A182 Gr F316L (B16.5) for weld neck flange at temp (-)70 deg C., however B16.5 doesn’t tabulated any equivalent pressure (Group-2.3 per B16.5)below -29 C. Is this material suitable for temperature -70 degree Centigrade while ASME B16.5 doesn’t provide any allowable at this temperature.
Actually In one of my project PMS having temp range of -75 to 150 Deg C, and tabulated ASTM A182 Gr F316L (B16.5) for flanges. My piping has operating temperature of -70 Deg C and Design 85 Deg C.
I need to check flange leakage but unfortunately no allowable values given in B16.5.
I request your expert views on above.

I have worked with cryogenic field where MDTM is up to -196 Deg Celcius and flange used for the field of cryogenics we used that same material : ASTM A 182 Gr F 316L.In my opinion there will be no problem to use this flanges for lower temperature services.

steel matiarial can be used up to -200 deg C without impact, and also
We are using SA 182 F 304L or 316lL at -190 Deg C in cryogenic
service.
