Dear Sir

Good morning. I want your help in the following matter

We are doing the CWS/CWR line having dia from 80" ~ 112" & thickness over 20 mm upto 28.58 mm O.P 5.5 Kg/Cm2.

We are carrying PWHT due to the thickness requirement, but we want to deviate as the para 331.2.2 of B31.3. So if anybody have qualified WPS without PWHT in such cases, please guide me & send the WPS for the reference purpose.

With warm regards
