Re: [MW:22941] Requirements Of PWHT for the Cross Country Pipe Lines - Reg

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 Experts,

We have done PQR with PWHT for the Material APL 5L Grade X60, and the coupon Size is 40 Inch & the Thickness is 38 mm with the Construction code application of API 1104 (Cross Country Pipe Line)

Based on the results we prepared WPS Also, But, As per API 1104 for 38.00 mm THK PWHT is not required 

Now The Aramco PID instructed to follow the WPS to do all the Joints PWHT

What is the remdy for this & hat should we do 

Kindly drop your advise 


Thanks & Warm Regards,
