Hi,

Since your WPS qu

 

Thanks & Regards,alified with PWHT, you can't use this for without PWHT jobs.

Since your construction code doesn't reqire PWHT you have 2 option.

01. Do new WPS/PQR without PWHT

02. If you don't want to prepare new, then follow as per your existing WPS (as your client said)

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

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,

Amul Raj T
