Low temperature
Low temperature
(OP)
It's a long time since I used the ASME VIII, Div.1 routine for low temperature service and I've fogotten how the code treats the Test pressure (at ambient temperature) for a Design temperature below ambient. Also, I don't have a copy of ASME VII to hand.
Can someone remind me of the rules, please?
Thanks,
PPVE

RE: Low temperature
ASME II Part D stress values at ambient are actually applicable for the temperature range -20 to 100degF, so your stress ratio at test temperature should be 1.0.
A general note to Table 1A of ASME II Part D also states: "Stress values for -20 to 100degF are applicable for colder temperatures when toughness requirements of Section III or Section VIII are met."

RE: Low temperature
What do the new rules say, in brief, of course?
Can I take advantage of the low temperature properties?
Any help greatly appreciated.
