Preheat mentainance
Preheat mentainance
(OP)
Dear All,
I am working in a power plant construction project. The WPS says preheat maintainance at 150 degree C for one hour for A 213 T22 joints. But contractor is saying that as per ASME section IX preheat mentainance is not an essential variable. Shall We insists for preheat maintanance as given in WPS...?
Thanks in advance.

I would venture to say the contractor doesn't understand the real reasons for preheat. Scary!
