LNG piping
(OP)
Thanks for the input to all. OK here is the situation, we will be welding TP304L piping with operating temps down to -162C. Relevent codes are B31.3 and CSA Z276. It looks as though B31.3 allows no impact values required for austenitic S/S to - 101C. Will I need to design a new weld procedure with Charpy's to accommodate the lower temperatures?
