Hi There,

 

We have an existing WPS, The existing WPS doesn’t have a cold service specification, and we would like to do a test coupon from that WPS and have it charpy tested, so we can revised the existing WPS. Now the requirement of the client is -70 degrees Celsius. Is that alright or do we have to do another PQR? Code is ASME IX.

 

 

Thank you,
