SA234 WPB
(OP)
ASME BOILER & PRESSURE VESSLE CODE II PART A - FERROUS MATERIAL SPECIFICATIONS, SA-234, Para 7.5 states: Liquid quenching followed by tempering shall be permitted for all grades when approved by the purchaser.
I have a recieved a request to accept some material that has been manufactured this way. I checked the mill test report and all data meets the requirements of SA-234. I'm inclined to accept the fittings, but I'm cautiously curious why does the spec require that this be approved by the purchaser? Am I missing something? Any problem with liquid quenching fittings?

I don't believe there would be welding issues with PWHT unless impact testing is required.
