Also you can mention in your WPS that the WPS having PWHT is only applicable for thickness above 38mm to the maximum thickness qualified . Please refer SAES W - 012 and SAIC - W- 2042.

Dear Amul,
What is the design code.? If it is ANSI B 31.4 or B 31.8 then PWHT is required above 38 mm.
Design code will specify PWHT requirements which is to be incorporated while making the WPS using section IX or API 1104.
Regards,
Anup
Refer scope of work, Isometric drawing and P & ID to find the applicable code.
Section 434.8.9 specifies about PWHT is ANSI B 31.4

Anup

Dear Expert,
Our vendor had purchased normalized plates from Sumitomo of steel making and Mill Cert clearly stated that the plates have been normalized but no sign or stamp “N” on plate. The problem is when the client reviewed and witnessed it, they don’t believe that the plate has been normalized and the question is what test needs to be conducted to prove that the plate has been normalized?
For your info: what do you think if the client ask for the following test:
1. Tensile test and the specimen needs to be normalized first prior to test, acceptance criteria as per mill cert.
2. Scanning Electron Microscope (SEM), acceptance criteria: no residual stress in the plate.
Your quick response is highly appreciated.
Regards
Dani
