PWHT P5A
PWHT P5A
(OP)
In ASME VIII UCS-56 pg 158, it lists a PWHT temp of 1250F though the old welding engineer has a temp of 1375F listed in the WPS. I can't find any reasons why you would increase the tempature that much. He is no longer here to ask why. If anyone has any reasons or experience with P5a and what they have done in the past it would be greatly appreciated.
