API RP945 does not cover SS equipment/piping in amine service. Hence the question is whether PWHT is required for CS equipment/piping which is fully clad with SS316L and handling Rich amine service or would the velocity restrictions (less than 3 m/s or 10 f/s) suffice?
Maximum operating...
As per ISO 15156-3 table A.2, hardness for Austenitic SS described in A.2 is 22 HRC. Is the value for the parent metal or the same hardness limit applies to HAZ and Weld as well? Thanks in advance!
