Re: [MW:33926] Impact test requirements for PQR

Depends on Design code and applicable impact test requirements else you can use X46 to X46 pqr

Just to add. Charpy Impact test at MDMT (Minimum design Metal temperature) but if you perform at -48degC it can be used in the future.

API 5L X60 if ordered with special impact test requirement at -48degC then it will meet the requirement.

See below snap shot below.

Thanks & Regards

Impact test shall be performed at -48degC

and pls ensure whether API 5L X60 is suitable for this temperature from the MTC
