Inox Steel India is a leading manufacturer, stockist, and exporter of API 5L Line Pipes in Grades B to X80. These pipes are widely used for oil & gas transmission, petroleum pipelines, offshore pipelines, water supply networks, structural purposes, and long-distance high-pressure pipeline systems.
With one of India’s largest inventories of API 5L PSL1 and PSL2 pipes, we supply seamless, ERW, LSAW, HSAW, and DSAW variants to meet project requirements across India, Middle East, Africa, Europe, and North America.
Every API 5L pipe supplied by Inox Steel India undergoes hydro testing, CVN impact testing (PSL2), ultrasonic inspection, weld seam inspection, NDT, coating inspection, and dimensional accuracy checks as specified under API 5L Appendix standards.
Our API 5L pipes are used for onshore and offshore transmission of crude oil, natural gas, petroleum products, water, and slurry, with coating options such as 3LPE, 3LPP, FBE, Coal Tar, and Internal Epoxy.
API 5L is the American Petroleum Institute specification for line pipes used in:
API 5L includes two product levels:
High grades like X60, X65, X70, and X80 offer superior yield strength, high toughness, and low carbon equivalent, making them suitable for high-pressure, long-distance, and deep-water pipeline systems.
We ensure full compliance with API Monogram requirements and international project specifications.
