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

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