Pipeline steel pipe faces many challenges

Posted:2021-09-27 09:14:23

Pipeline steel pipe, which is a kind of steel used in oil and gas pipeline transportation systems, includes seamless steel pipe and welded steel pipe.

Pipeline steel pipe faces many challenges, include: most of the oil and gas fields are located in polar regions, ice fields, deserts, and oceans, where natural conditions are relatively harsh; or in order to improve transportation efficiency, the diameter of pipeline steel pipe has been continuously expanded while the transmission pressure has been continuously increased.

Considering the comprehensive conditions of oil and gas pipelines, pipeline steel pipe should have good mechanical properties (high strength, high toughness, etc.), and should also have a large diameter, weldability, resistance to severe cold and low temperature, corrosion resistance, etc.
