Tianjin xinyue steel group manufactures seamless carbon steel pipes from carbon steel grades that fulfil API 5L and ASTM A106 specifications. The pipes are supplied in a broad range of outer diameters, typically from 50 mm up to 600 mm, with wall thicknesses commonly between 3 mm and 30 mm. The seamless construction eliminates weld lines, providing superior strength and pressure resistance. The product data highlights compliance with international pressure‑pipe standards.
Standard mechanical properties for API 5L pipe steel include a tensile strength of 415 - 485 MPa and a yield strength around 245 MPa after normalising. Typical dimensional tolerance on the outer diameter is ±0.05 mm, and surface roughness is usually Ra 1.6 µm in the mill finish. These pipes are designed to withstand pressures up to 1.0 - 1.5 MPa in schedule 40 applications. The material’s carbon content and alloying elements give it good weldability and corrosion resistance for oil‑ and gas‑transport pipelines.
Key markets for these pipes are oil and gas pipelines, petrochemical plants and large‑scale construction projects. Importers should verify the pipe schedule, pressure rating and applicable certification before committing to a purchase. Trade terms such as FOB, CIF and payment conditions need to be agreed directly with the supplier.

When evaluating a purchase, confirm the exact pipe schedule, diameter, wall thickness and pressure rating required for your project. Request the latest mill test certificate and any API 5L compliance documentation to ensure the steel chemistry and mechanical properties meet your specifications. Verify that the supplier can provide third‑party inspection reports if your contract mandates independent verification.
Discuss logistics early: agree on the preferred Incoterm - FOB, CIF or another arrangement - and obtain an estimated lead time based on current production capacity. Payment terms such as T/T, L/C or open account should be negotiated and recorded in the purchase agreement. Clarify any packaging requirements, such as bundling or protective coatings, to avoid damage during transit.
Plan for quality control by arranging a pre‑shipment inspection or on‑site testing at the supplier’s facility. Standard checks include ultrasonic wall‑thickness measurement, hydrostatic pressure testing and visual inspection for surface defects. Ensure the supplier provides a final inspection report, heat‑treatment certificate and compliance declaration before the goods are loaded for shipment.
