Thanks for your all response, 

we done the impact at -55°C in PQR, My query is our service fluid is water and service temp is 0° to 90°C, i believe then the thickness range in WPS we can use 5 mm to 50.4 mm.  

Design Code: B31.3

Qualification Standard : ASME Sec IX

Experts,

please advise below,  I believe because of our service temperature the impact test is not required, please guide me. 

PQR material - A707 L5 CL3 to API 5L Gr X65

Thickness coupon: 25.4 mm

WPS qualified range is : 5 to 50.8 mm

Design code : B31.3

Qualification Standard : ASME Sec IX

Our Project MDT : 0° to 90°C

Service : Water

PWHT : Yes

Pre heat : Yes
