The product offered by Threeway Steel Co., Ltd. in China is a line pipe designed for sour service environments. It is manufactured from carbon‑steel grades API 5L X52, X60 and X65 that meet NACE MR0175/ISO 15156 requirements. Pipe dimensions cover outer diameters from 6 inches to 60 inches with wall thicknesses up to 25 mm, supplied in either longitudinal‑seam (LSAW) or spiral‑seam (SSAW) forms. The material is intended for long‑distance oil and gas transmission where hydrogen sulfide corrosion is a concern.
Carbon‑steel API 5L pipes for sour service are characterised by controlled chemistry, low sulphide inclusion levels and a specified yield strength for each grade. Typical mechanical properties include a minimum yield strength of 355 MPa for X52, 380 MPa for X60 and 410 MPa for X65. Standard industry practice also applies a surface coating such as three‑layer polyethylene or epoxy to protect against external corrosion. The pipes are usually supplied in bundled steel strips with protective film and marked according to ISO 11960.
End users include pipeline contractors, refinery feedstock transporters and offshore gas facilities that require reliable sour‑service performance. Threeway Steel does not disclose minimum order quantity, lead time or pricing, so importers should request these details directly from the company. Trade terms are typically negotiated on a CIF or FOB basis, with payment terms ranging from LC to T/T after inspection. Buyers are advised to verify the NACE certification and request a mill test report for each batch before shipment.

Importers should first confirm that the pipe chemistry complies with NACE MR0175 and that the mill test report matches the specified grade (X52, X60 or X65). Verify the outer diameter, wall thickness and coating type against project requirements before placing an order. Request documentation of the coating system and any heat‑treatment records to ensure long‑term sour‑service performance.
Logistics for line pipe usually involve container or bulk vessel loading, with the supplier able to offer FOB Ningbo or CIF Shanghai terms. Because lead time is not disclosed, ask Threeway Steel for a production schedule and estimated shipping window. Payment terms are commonly a letter of credit issued at sight or a telegraphic transfer after successful inspection; negotiate these terms in the contract.
Quality control should include visual inspection of the coating, dimensional checks of diameter and wall thickness, and non‑destructive testing for weld integrity where applicable. Arrange for a third‑party inspection agency to verify compliance with the NACE standard and to review the mill test report before shipment. Obtain all certificates and inspection reports prior to acceptance of the goods.
