1) When the C-pump loses prime or when the pressure falls below a certain pressure (<80 psi), this action should actually trigger a pneuma

Heating and cooling rate shall be 220ºC/Hr Maximum" and the ranges of the temperature "675ºC to 690ºC ASME I" and "700ºC to 760ºC ASME B31.1"

For which reason, for the same material (P91, 9%Cr 1% Mo ) PWHT's temperatures change depending on the used code?
