The Large Diameter LSAW Steel Pipe supplied by Hunan Great Steel Pipe Co., Ltd. is a longitudinal submerged‑arc welded pipe intended for high‑pressure oil, gas and water transmission. It is manufactured from carbon steel to API 5L grades X42, X52, X60, X65 and X70, with nominal diameters ranging from 16 in to 100 in and wall thicknesses between 6 mm and 40 mm. The pipe conforms to API 5L, ASTM A252 and GB/T9711 standards and is offered in lengths from 6 m to 18 m.
Carbon steel of the specified API grades provides the tensile strength required for demanding pipeline networks. Typical pressure ratings for API 5L pipe reach up to 1,200 psi, while standard coating options such as light oil, hot‑dip galvanising, epoxy or bare finish protect against corrosion. The product is commonly supplied in bundled or PVC‑wrapped packs to facilitate handling and transport, and it undergoes hydrostatic testing, X‑ray, ultrasonic and eddy‑current inspection as part of quality assurance.
These pipes are selected by EPC contractors, utility companies and infrastructure developers for long‑distance transmission projects, offshore platforms and marine construction. Trade terms usually include FOB or CIF options, with MOQ flexibility that depends on the project’s scale. Importers should obtain the supplier’s certification files, inspection reports and agreed Incoterms before finalising a purchase contract.

Prior to ordering, confirm the pipe’s nominal diameter, wall thickness, length and coating type match the project specifications. Request the supplier’s mill test certificates, API 5L compliance documents and any third‑party inspection reports to validate material and workmanship. Ensure the correct HS classification for customs clearance is agreed upon.
Discuss logistics early: decide whether FOB from the Changsha port or CIF to the destination port best suits your supply chain. Clarify the expected lead time for the required sizes and negotiate payment terms such as TT or LC, documenting these in the purchase agreement. Verify that the supplier provides a detailed pro‑forma invoice reflecting the agreed specifications.
Arrange independent inspection before shipment, focusing on dimensional verification, wall thickness measurement and coating integrity. Ask for inspection certificates from recognised bodies such as SGS or BV. Upon receipt, perform a visual and dimensional check to confirm the pipe conforms to the supplied test reports and specifications.
