Steel pipeline manufacturing.
API 5L PSL1 X80 steel plate yield strengthX80 pipeline steel American-made unit yield strength of the first two small value X80 is the small yield strength of line pipe 80,000psi (552MPa).
Main properties of API 5L PSL1 X80 steel plateX80 pipeline steel has high strength, high toughness, good weldability, certain resistance to HIC and SSC, and the improvement of pipeline steel grade can save construction costs.
X80 steel plate chemical element analysisPipeline steel Early pipeline steel has always used ordinary carbon steels of C, Mn, and Si types, which focused on performance in metallurgy and did not have strict regulations on chemical composition. Since 60 years, with the increase of oil and gas pipeline transportation pressure and pipe diameter, low-alloy high-strength steel (HSLA) has been adopted, mainly delivered in hot rolled and normalized conditions.
Application of API 5L PSL1 X80 steel plate:
X80 pipeline steel is mainly used in oil and gas pipelines.
