Threeway Steel Co., Ltd. supplies seamless carbon‑steel pipe manufactured without welded joints. The product is offered in grades 20#, 45# and A106 Grade B, meeting ASTM, API 5L and GB/T standards. Pipe diameters cover DN15 (≈15 mm) up to DN1200 (≈1200 mm) with wall thicknesses ranging from 1 mm to 50 mm. Lengths can be supplied up to 24 m, which is the maximum roll length recorded in the catalogue.
The steel chemistry typical for these grades includes carbon 0.15‑0.22 %, silicon up to 0.35 % and manganese up to 1.5 %, delivering a typical tensile strength of 350‑550 MPa. Such mechanical performance is suitable for oil‑and‑gas pipelines, boiler systems and structural applications. End preparations are not explicitly listed, so standard plain, beveled or threaded ends are assumed typical for this class of pipe. Surface protection options such as oil‑based paint or galvanising are commonly applied, and the supplier can arrange these upon request.
The catalogue does not state a minimum order quantity, and buyers should confirm the required volume directly with the supplier. Delivery schedules are quoted as per customer requirement, with the supplier indicating the ability to ship after payment confirmation. The company lists a broad range of international standards, allowing buyers to request specific certifications or third‑party inspection as needed.

Prior to ordering, confirm the exact grade, diameter, wall thickness and length required for your application. Ask for the latest mill test report and verify that the pipe complies with the relevant ASTM or API standard. If a particular surface coating or anti‑corrosion treatment is needed, discuss the specification and any additional testing requirements with the supplier.
Agree on the preferred incoterm, such as FOB Changsha or CIF Shanghai, and establish payment terms, commonly a TT deposit with balance on document presentation. Shipping method should reflect the order size; the supplier can arrange container loading for smaller volumes or bulk freight for larger shipments. Clarify the expected lead time, which is quoted as per customer requirement, and allow extra days for customs clearance and inland transport.
Arrange a third‑party inspection or request the supplier’s ISO audit documentation to ensure quality compliance. Obtain a detailed packing list, material test certificates and, if necessary, non‑destructive testing results for the seamless pipe. Proper documentation will smooth customs clearance and provide confidence in the received product.
