API 5L is a standard of API 5L pipe. Specifications for API 5L adhere to the International Organization for Standardization ISO 3183. The API 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 standard-weight and extra-strong threaded line pipe; and standard-weight plain-end, regular-weight plain-end, special plain-end, extra-strong plain-end, special plain-end, extra-strong plain-end pipe, as as well as bell and spigot and through-the-flow line(TFL) pipe. 


Grades covered by this specification are A25 ,A ,B (and the following "X" Grades), X42, X46, X52, X56, X60, X65, X70, X80. The two digit number following the "X" indicates the Minimum Yield Strength (in 000's psi) of pipe produced to this grade. 


Pipe manufactured to ASTM106 Grade A or B are not interchangeable with API 5L. Requirements to API 5L X grades are more stringent, rolled grades are not acceptable and rework is not allowed. Moreover, particular attention is given to toughness and toughness tests for sour services and higher pressure & temperature classes. 


Applications and benefits of API 5L Line Pipe:


1. API 5L line pipe is preferred in long pipelines due to its inexpensiveness, so it is widely used in gas, water and oil transportation.
2. API 5L line pipe can resist to crack propagation, so it used to pipeline steel.
3. Line Pipe and Sour Service Line Pipes
