API 5L: This is a pipeline standard developed by the American Petroleum Institute to specify the technical requirements and performance standards of pipeline steel pipes. PSL2: is a product specification level technical requirement in API 5L. It provides higher technical requirements than PSL1, including increased chemical composition, notch toughness, strength performance and supplementary NDE (non-destructive testing) mandatory requirements. X42QS: where "X42" indicates the yield strength grade of the steel pipe, that is, when the steel pipe is subjected to external forces, the maximum stress value of the unit area is 42,000 psi (pound force per square inch). The "QS" indicates the quality level of the steel pipe, which means that the steel pipe has undergone strict quality control and inspection in the manufacturing process to ensure its high-quality product performance.

API 5L PSL2 X42QS Seamless steel pipe is mainly made of high-quality carbon structural steel or low-alloy high-strength steel, with high mechanical strength and good weldability. The production process includes tube preparation, perforation, rolling, heat treatment, straightening, cutting and other steps to ensure the high quality and stability of the steel pipe.

 

API 5L PSL2 X42QS Seamless steel pipe application range:

 

Oil and gas field: API 5L PSL2 X42QS seamless steel pipe is mainly used in oil and gas transmission pipelines, wellhead devices, submarine pipelines and other key parts, its high strength and good welding performance to ensure the safe and stable operation of the pipeline system.

 

Chemical field: Used to manufacture reactors, storage tanks, heat exchangers and other equipment, its corrosion resistance and high temperature properties make it the preferred material for chemical equipment manufacturing.

 

Power field: Used in the manufacture of boilers, steam turbines, generators and other equipment, its high strength and good thermal stability can meet the high requirements of material properties in the power industry.

 

In addition, X42QS seamless steel pipe can also be used in construction, Bridges, machinery and other fields, its excellent performance and a wide range of applications make it one of the important materials in the industrial field.
