ASTM A53/A106 API 5L Gr.B ERW Carbon Steel Pipe Round Tube for Structure
1.Product Description
API 5L carbon steel pipe is a carbon and low‑alloy steel welded and seamless line pipe manufactured in accordance with API Specification 5L, Line Pipe. First published in 1924, this specification remains the world’s most essential manufacturing and acceptance standard for oil and gas pipelines. Steel grades include Grade B, X42, X52, X60, X65, X70, and X80, where the number indicates minimum yield strength in ksi. Manufacturing processes cover SMLS, LSAW, SSAW, ERW, and EFW. Quality levels are PSL1 (standard) and PSL2 (stringent), with the latter imposing stricter chemistry, toughness, and NDT requirements. OD ranges from 10.3mm to 2032mm, wall thickness is customizable, and lengths are available in fixed or random sizes.
2. Product Applications
Long‑distance oil/gas trunk lines and subsea pipelines
Oilfield gathering networks, water injection, and polymer injection lines
High‑temperature, high‑pressure process piping in refineries and chemical plants
Urban high‑pressure gas grids, district heating, and large‑scale water diversion projects
Offshore jacket structures, bridge piling, and heavy steel structural load‑bearing members
3. Product Advantages
Full steel‑grade coverage from B to X80, matching various pressure levels and geographic conditions
PSL2 grade offers excellent low‑temperature impact toughness and crack‑arrest performance for extreme environments
Sour service series available with HIC and SSC validation for H₂S‑containing media
Tightly controlled carbon equivalent (CEV) ensures superior field weldability
Full traceability with key process parameters recorded, pipe end markings linked to documentation
High dimensional precision facilitates on‑site fit‑up and automatic welding, improving construction efficiency
Compatible with multiple anti‑corrosion coatings including FBE, 3LPE, and 3LPP, with design life exceeding 50 years
