Natural Gas Transport X70 Steel Line Pipe With Special Couplings
Steel Line Pipe API 5L Gr. 70 PSL 1 for Natural Gas Transport
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.
API 5L X70 PSL1 Pipe are used in onshore and offshore oil and gas pipelines requiring critical service, high performance and tight tolerances.
Standard: API 5L
