Sour Service Welded Steel Line Pipe API 5L Standard X80Q Material
Seamless Line Pipe Carbon Steel Pipe API 5L X42Q PSL2 Critical Service
The API SPEC 5L specification provides standards for pipe suitable for use in conveying gas, water, and oil in the natural gas and oil industries. The API SPEC 5L covers seamless and welded steel line pipe. It includes plain-end, threaded-end, and belled-end pipe, as well as through-the-flowline (TFL) pipe, and pipe with ends prepared for use with special couplings.
We offer a full range of high performance line pipe tailored to the needs of the global oil and gas industry and the unique challenges of transportation environments. Our welded and seamless line pipe is used around the world to transport crude oil, natural gas and natural gas liquids from producing fields to processing plants or refineries.
To meet the oil and gas industry’s need for safe and dependable onshore transportation, every joint of our line pipe is manufactured at an ISO 9001 compliant facility to meet API 5L standards. All product is tested in-house and delivered with outstanding surface quality that is suitable for coating.
