API 5L is for use in conveying gas, water, and oil in the natural gas and oil industries, and covers seamless and welded steel line pipe.
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.
Line Pipe / Sour Service Line Pipes
API 5L is a seamless pipe and welded carbon steel pipe material specification. API 5L pipes are widely used to transport oil, water, and gases in the pipeline industry. Depending on the strength, schedule, and service requirements API 5L pipes are manufactured in various grades and are suitable for both onshore and offshore applications.
API 5L pipes in the oil and gas, water, and petrochemical industries are available in two Product Specification Levels (PSL) depending on quality levels. The first one is PSL1 which provides a standard quality level. The other one PSL2 provides additional mandatory requirements in strength, chemical composition, NDT, or notch toughness.
API 5L Standard is including steel grade(GR.B，X42 ，X46，52，X56，X60，X65，X70).
