Re: [MW:14631] Allowable temp range for SS316/316L

Dear Mr Bagesh,

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.

Good Morning Sir,

 

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.
