API 5L standard specifies requirements for the manufacture of seamless and welded steel pipe for use in pipeline transportation systems in the petroleum and natural gas industries. API 5L standard include two levels: PSL1 and PSL2. PSL2 has more strict requirements for performance and quality of steel pipes.
Steel grades of API 5L standard
Common class: API 5L PSL1 PSL2 Gr.B, sour service pipe
Medium grade: API 5L X42 X46 X52
High grade: API 5L X56 X60 X65
Premium high grade: API 5L X70 X80
For PSL2 pipe comes with suffix letter of N, Q, M, which represents the different manufacturing process and delivery condition. Such as API 5L X60Q. Letter"N" means that Normalized; Letter"Q" means that Quenched and Tempered; and Letter"M" means that Mechanical Treatment.
Application field of API 5L standard steel pipes
API 5L standard steel pipes have high pressure resistance and good corrosion resistance, which are widely used for transporting of petroleum, natural gas, and other fluids.
