Different Manufacturing TypesĪPI 5L specification covers the manufacturing types in welded and seamless. Meanwhile other fluids like steam, water, slurry also could adopt the API 5L standard for the transmission purposes. In a word, API 5L pipe is the carbon steel pipe applied to the oil and gas transmission system. This standard is not applicable to cast pipe.” In API SPEC 5L 46th Edition, it is defined the scope as:”Requirements for the manufacture of two product specification level (PSL1 and PSL2) of seamless and welded steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries.
Tolerances on pipe diameters, wall thickness, out-of-roundness
Material specifications (Chemical and Mechanical) Product Specification Level (PSL1 and PSL2) Here we will do a brief introduction of API 5L pipe and related standard specifications with below aspects:ĭifferent Grades (Covers B, X42, X46, X52, X60, X65, X70) Surface Treatment: Natural, Varnished, Black painting, FBE, 3PE (3LPE), 3PP, CWC (Concrete Weight Coated) CRA Clad or Lined Length Range: SRL (Single Random Length), DRL (Double Random Length), 20 FT (6 meter), 40FT (12 meter)or customized Manufacturing Types: Seamless (Hot Rolled and Cold Rolled), Welded ERW (Electric resistance welded), SAW (Submerged Arc Welded) in LSAW, DSAW, SSAW, HSAW
SCH 20, SCH 40, SCH STD, SCH 80, SCH XS, to SCH 160 Product Specification Level: PSL1, PSL2, onshore and offshore sour services API 5L the implementation standard of steel pipe for pipeline transportation system and specification for line pipe. Materials covers API 5L Grade B, X42, X46, X52, X56, X60, X65, X70, X80 PSL1 & PSL2 onshore, offshore and sour services. API 5L pipe is carbon steel pipe used for oil and gas transmissions, it includes the pipes manufactured in seamless and welded (ERW, SAW).
