The item is a seamless line pipe made from carbon steel grade API 5L X52QS or X56QS, designed for sour service in oil and gas pipelines. The supplier specifies compliance with API 5L PSL 2 and NACE MR0175/ISO 15156 standards, and the pipe is intended for hydrogen sulfide environments. The product is manufactured in China and shipped from the supplier’s facility in Changsha, Hunan. No explicit minimum order quantity is listed, so buyers should confirm the required tonnage with the supplier.
Typical sour‑service pipe dimensions range from an outer diameter of 2 inches to 24 inches with wall thicknesses between 2.77 mm (Schedule 5) and 12.7 mm (Schedule 40), which are standard for mid‑size transmission lines. Mechanical properties usually include a tensile strength of 490 - 620 MPa and a yield strength of 355 - 420 MPa, values that meet the API 5L X52/X56 specifications. The pipes are supplied without external coating, allowing users to apply internal or external protective systems as required; this is a typical practice for sour‑service pipelines. Dimensional tolerance for outer diameter is generally ±0.2 % of the nominal size, a standard tolerance for seamless line pipe.
End users such as upstream oil producers, refineries and petrochemical plants request mill test reports, NACE‑compliant hardness tests and ultrasonic inspections before acceptance. Buyers should negotiate incoterms (FOB, CIF or EXW) and payment terms directly with Threeway Steel, and ask for lead‑time estimates based on the required grade and size. Because the pipe is used in high‑risk sour environments, a third‑party quality audit and documentation of NACE certification are advisable prior to shipment.

Their public information indicates a focus on supplying carbon‑steel pipe products for industrial applications, particularly for the oil and gas sector.
The listing highlights that the pipe meets API 5L and NACE specifications, but it does not disclose production capacity, MOQ or specific certification numbers. Prospective buyers should request detailed mill test reports, verify the exact grade (X52QS or X56QS) needed for their project, and confirm any additional processing such as threading or coating that may be required before shipment.
This sour service line pipe is specifically engineered for oil and gas transmission in hydrogen sulfide environments, meeting API 5L PSL2 requirements and NACE MR0175/ISO 15156 standards. Available in grades such as X52QS and X56QS, the pipe offers superior resistance to sulfide stress cracking and corrosion under stress. Commonly used in upstream oil and gas, refinery, and petrochemical applications, this seamless line pipe ensures reliable performance in the most demanding sour well and pipeline conditions. Pricing reflects grade, wall thickness, and quantity ordered.

Before ordering, confirm that the pipe grade (X52QS or X56QS) matches the project’s sour‑service requirements and request the latest mill test report and NACE certification to verify chemical composition and mechanical properties. Verify that the supplier can provide dimensional inspection data, especially outer‑diameter tolerance and wall‑thickness measurements, to ensure compliance with design specifications.
Logistics for these steel pipes usually involve bulk freight; buyers should agree on an incoterm such as FOB or CIF and obtain a clear lead‑time estimate based on the required sizes and quantities. Because the pipes are heavy, arrange for suitable container or break‑bulk handling and discuss payment terms, preferably using a letter of credit, to protect both parties during the transaction.
A pre‑shipment third‑party inspection can confirm compliance with API 5L tolerances, NACE standards and any required coating procedures. Retain the mill test report, NACE certificate and inspection certificate for customs clearance and future quality audits. Conduct a post‑arrival visual inspection to check for transport damage before accepting the shipment.
