The product is a large‑diameter spiral welded steel pipe, marketed as Hunan Tube, supplied by Hunan Great Steel Pipe Co., Ltd. in Changsha, Hunan, China. It is manufactured from carbon‑steel grades Q235B, Q345B and API 5L grades B to X70, with outer diameters ranging from 219 mm to 3048 mm and wall thicknesses between 5 mm and 25 mm. Production methods include SSAW (Spiral Submerged Arc Welding) and HSAW (Helical SAW).
These dimensions align with industry standards for oil‑ and gas transmission, water supply and structural piling, where API 5L, GB/T 9711 and ASTM A252 specifications are routinely applied. Typical surface treatments such as hot‑dip galvanising, electro‑galvanising and oil‑based anti‑rust coating are offered to enhance corrosion resistance for underground installations. Standard non‑destructive testing - ultrasonic, X‑ray, hydraulic and eddy‑current - is performed to verify weld quality and dimensional accuracy.
Primary buyers are pipeline contractors, water utilities and construction firms that require reliable long‑run pipe sections. The supplier mentions bulk export packaging in bundles or single shipments and invites bulk trade enquiries. Exact minimum order quantities, lead times and payment terms are not disclosed and should be confirmed directly with the company.

Importers should first request material test reports confirming the carbon‑steel grade and chemical composition, as well as certificates for API 5L compliance. Verify the outer‑diameter and wall‑thickness tolerances against project drawings before confirming the order.
Shipping terms are typically FOB Changsha port, but the exact Incoterm and freight forwarder must be agreed with the supplier. Clarify packaging - whether pipes will be bundled on pallets or shipped individually in PVC‑wrapped crates - and obtain an estimated lead time for the required dimensions.
Arrange third‑party inspection covering NDT results, surface coating thickness and dimensional checks. Ask for the inspection certificate, mill test report and a declaration of conformity before releasing payment, to ensure the delivered pipes meet the specified standards.
