This LSAW pipe from Central Steel Manufacturing Co., Ltd. is a longitudinal submerged arc welded carbon steel pipe, produced in outer diameters from 12 to 64 inches and wall thicknesses of 5 to 50 mm. Standard lengths range from 6 to 18 meters, with grades covering API 5L (X40 to X70, PSL1 and PSL2), API 5CT, ASTM S235JRH, S275JRH, and S335JRH, as well as JIS, DIN, EN, BS, AWWA, and JZS standards for water, gas, and oil transmission. The pipe is beveled at both ends and offered with internal and external coating options for corrosion protection in demanding environments.
The material is carbon steel, with API 5L grades providing yield strengths from 276 MPa (X40) to 552 MPa (X80), while ASTM S235JRH and S275JRH offer minimum yield strengths of 235 MPa and 275 MPa respectively, typical for structural and low-pressure applications. LSAW pipes are known for their uniform wall thickness and high weld integrity, achieved through submerged arc welding under a flux layer, which reduces oxidation and produces a smooth, consistent bead. These pipes are standard for large-diameter, high-pressure pipelines where seamless alternatives are cost-prohibitive.
Primary applications include oil and gas pipeline construction, water mains, structural piling for coastal and infrastructure projects, and low-pressure delivery systems. Buyers typically source these pipes for large-scale civil engineering, energy transport, and municipal water networks. The pipes are export-packaged to prevent damage during transit, and the supplier’s location in Changsha, Hunan, positions it well for logistics to major Chinese ports. Confirm MOQ, incoterms, and coating specifications directly with the supplier.

Before ordering, verify the exact grade and standard compliance for your project, as API 5L, API 5CT, and ASTM grades have distinct mechanical properties and testing requirements. Request mill test certificates (MTCs) from Central Steel Manufacturing Co., Ltd. to confirm chemical composition, tensile strength, and impact testing results. For oil and gas applications, ensure the pipes meet PSL2 requirements if sour service resistance is needed.
Confirm logistics details such as port of loading (likely a major Chinese port near Changsha), incoterms (e.g., FOB, CFR, or CIF), and packaging standards for export. LSAW pipes are typically bundled and secured for sea freight, but specify if additional protection (e.g., VCI packaging) is required for humid or corrosive transit conditions. Lead times for large-diameter pipes can vary; request a production schedule aligned with your project timeline.
Quality checks should include visual inspection for surface defects, ultrasonic testing (UT) for weld integrity, and hydrostatic pressure tests to verify leak resistance. For coated pipes, inspect the coating thickness and adhesion using holiday detectors or pull-off tests. Request documentation such as MTCs, NDT reports, and third-party inspection certificates (e.g., from SGS or Bureau Veritas) to ensure compliance with your specifications.
