Abstract:
The present disclosure relates to methods and treatments of linepipe steels that transport one or both of crude oil and natural gas. More particularly, the present disclosure relates to sulfide stress cracking resistance of carbon steels for use as linepipe in transporting crude oil and natural gas by alternative thermo-mechanically controlled and/or one or more additional heat treatment processes.
