API 5L pipes are carbon steel pipes used for oil and gas transmissions. They include pipes manufactured in seamless and welded (ERW, SAW). The grades include API 5L Grade B, X42, X46, X52, X56, X60, X65, X70, X80 PSL1 & PSL2 onshore, offshore and sour services. API 5L is the implementation standard of steel pipe for pipeline transportation systems and specification for line pipe.<\/p>\n

Here we will do a brief introduction of API 5L pipe and related standard specifications with the below aspects: In API SPEC 5L 46th Edition, the standard scope is defined as: “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. This standard does not apply to cast pipe.”<\/p>\n To summarize, API 5L pipe is the carbon steel pipe applied to the oil and gas transmission system. Meanwhile, other fluids such as steam, water, and slurry can also adopt the API 5L standard for their transmission purposes.<\/p>\n API 5L specification covers the manufacturing types in welded and seamless.<\/p>\n The API 5L welded pipe common types are as follows:<\/p>\n ERW: Electric Resistance Welded, for pipe diameter normally under 24 inches.<\/p>\n DSAW\/SAW: Double Submerged Arc Welding \/ Submerged Arc Welding, a substitute welding method of ERW for larger diameter pipes.<\/p>\n LSAW: Longitudinal SAW, for diameter up to 48 inches. Also called the JCOE manufacturing process.<\/p>\n SSAW\/HSAW: Spiral Submerged Arc Welded \/ Helical SAW, pipe diameters up to 100 inches.<\/p>\n
