API 5L General Information
The API SPEC 5L specification supplies standards for pipe suitable for use in conveying fuel, water, and oil within the all-natural gasoline and oil industries. The API SPEC 5L covers seamless and welded steel line pipe. It involves plain-end, threaded-end, and belled-end pipe, and also through-the-flowline (TFL) pipe, and pipe with ends prepared for use with particular couplings.

Pipe manufactured to ASTM106 Grade A or B are not interchangable with API 5L. Needs to API 5L X grades are more stringent; rolled grades will not be acceptable and rework just isn't allowed. Furthermore, distinct attention is provided to toughness and toughness exams for sour services and greater pressure & temperature classes.
