The American Petroleum Institute specification API 5L covers seamless and welded steel line pipe.  This is steel pipe for pipeline transportation systems in the petroleum and natural gas industries.  API 5L is suitable for conveying gas, water, and oil.  Size range is limited only by manufacturer’s capabilities.

Specifications for API 5L adhere to the International Organization for Standardization ISO 3183, which standardizes pipeline transportation systems within the materials, equipment and offshore structures for petroleum, petrochemical, and natural gas industries.  The technical committee authoring the standards recognized that there are two basic Product Specifications Levels (PSL) of technical requirements and therefore developed PSL 1 and PSL 2.  PSL 1 is a standard quality for line pipe where PSL 2 contains additional chemical, mechanical properties, and testing requirements. 

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.

AN Steel Supply stocks a full range of API 5L X56 PSL-1 & PSL-2 line pipe in seamless.

We can help supply all of the Carbon Steel API 5L Gr. X56 PSL1 Seamless Pipe or linepipe supplies that your company needs for use in the oil or natural gas industries. API 5L Line Pipe Specifications for these pipes regulate usage for standard Grade A and Grade B pipes, with Grade X indicating stronger variants for drilling, production and transport requirements for offshore, arctic, deep well or harsher environments. Longitudinally welded steel pipes / Carbon Steel API 5L Gr. X56 PSL1 Seamless Pipe are used in onshore and offshore oil and gas pipelines requiring critical service, high performance and tight tolerances. 

All products are industry-standard conforming to or exceeding API, ASTM, ASME, ANSI and other national and international standards.

Whether you need Carbon Steel API 5L Gr. X42 Seamless Pipe, standard length and diameter pipes and tubing or you need high strength, high tensile, heavy wall linepipe requirements for deep sour wells, drilling, offshore drilling and production, arctic exploration and production, or you need  Carbon Steel API 5L Gr. X56 PSL1 Seamless Pipe for natural gas, oil or water transport, then AN Steel and Alloys. can meet the demands of your company.

Applications of API 5L X52 PSL1 Seamless Pipe 
Carbon Steel is used in the most critical engineering applications and also in certain applications in the automotive sector. In addition, some of the value-added Carbon Steel products include steel for LPG cylinders, API grade, corrosion resistant steel, critical structural application steel, boiler quality, auto grades, precision tubes and medium/high carbon grades, among others.
 

Specification for line pipe API SPEC 5L (-09): specifies the requirements for the manufacture of two product specification levels (PSL1 and PSL2) of seamless and welded steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries.
