Product Details

What is API 5L steel pipe

API 5L pipe for pipeline transportation systems in the petroleum and natural gas industries.  This steel pipe is suitable for conveying gas, water, and oil. It covers PSL1, PSL2, Sour Services, for onshore and offshore pipelines. Manufacturing types including seamless and welded. PSL1 generally uses which equivalent to ASTM A106 B and A53 B. PSL2 is a higher specification level pipe, has more strict value on chemical and mechanical strength. Moreover, PSL2 requires more test methods. API 5L B PSL2 expressed with API 5L BN/Q/R/M. Sour Services: For sour pipelines like H2S environment, pipe material have typical restrictions on chemicals element of Carbon, P and S. API 5L B Pipe for Sour Service expressed in API 5L BNS/QS/MS
