API 5L pipe Supplier and line dimensions

API 5L Pipes stand out as one of the most trusted materials in the industry. Designed and certified under the globally recognized American Petroleum Institute (API) specification, API 5L line pipes are the backbone of critical pipeline infrastructure across the world.
Whether you’re working on a small utility project or a large-scale oil & gas transmission line, API 5L steel pipes offer consistent quality, strength, and performance.
 
API 5L is a specification that covers seamless and welded carbon steel line pipes intended for use in pipeline transportation systems. These pipes are suitable for conveying gas, water, and oil across both aboveground and underground installations. 
API 5L includes two major specification levels:
  • PSL1 (Product Specification Level 1) – Standard quality, basic mechanical and chemical properties.
     
  • PSL2 (Product Specification Level 2) – Enhanced performance, tighter tolerances, better mechanical properties, and additional testing for critical service.
     
API 5L pipes come in various steel grades such as X42, X46, X52, X56, X60, X65, X70, and X80 — each indicating its minimum yield strength in 1000s of PSI.
