Changsha Hunan Steel Co. Ltd. manufactures spiral welded steel pipes in Changsha, Hunan province, China. The pipes are produced from carbon steel grades ranging from Q235 and Q345 up to API 5L specifications from Grade B to X80. They are fabricated using the spiral submerged arc welding (SSAW/HSAW) process, which yields a continuous helix weld along the pipe length. The product complies with API 5L and AWWA standards for pressure pipelines.
Standard pipe diameters span from 300 mm to 2000 mm, with wall thicknesses typically between 6 mm and 30 mm. Lengths are commonly supplied in 6 m sections, which can be cut to size on request. The pipes can withstand design pressures from 1.0 MPa up to 10 MPa depending on the grade. Optional external coatings such as three‑layer polyethylene are often applied for corrosion protection in water and oil transport applications.
These pipes are used in water transmission networks, oil and gas pipelines and large‑scale civil engineering projects. Typical purchasers include utility companies, oilfield contractors and infrastructure developers. Trade can be arranged under FOB or CIF terms, with shipment from the port of Shanghai or Ningbo; exact incoterms should be confirmed with the supplier. Prospective buyers should verify the required diameter, wall thickness, coating type and any project‑specific certifications before ordering.

Before ordering, confirm that the pipe grade, diameter and wall thickness match the engineering specifications of your project. Request the latest mill test reports, API 5L certificates and any coating certification to ensure compliance with required standards.
Logistics for Chinese steel pipe shipments usually involve loading at the ports of Shanghai or Ningbo. Verify whether the supplier prefers FOB or CIF terms, the expected lead time for production and loading, and the payment method they accept. Arrange freight forwarding and customs clearance in advance to avoid delays.
Quality control should include third‑party inspection of dimensional tolerances, wall thickness, coating adhesion and non‑destructive testing such as ultrasonic examination. Obtain a full set of documentation, including the certificate of origin, compliance certificates and a packing list, before the cargo departs the factory.
