Seamless Steel Pipe
The product is a seamless carbon steel pipe offered by Hunan Prime Steel Pipe Co., Ltd. It conforms to grades 20, B, X42 and X65 and is manufactured to ASTM, API 5L and GB/T standards. Available outer diameters range from 1/8 inch (12.7 mm) up to 48 inch (1219 mm) with wall‑thickness schedules from standard (STD) through SCH160. Lengths are supplied in 3‑12 m increments according to the selected schedule.
The chemical makeup of the steel contains carbon 0.07‑0.20 %, silicon 0.17‑0.55 % and manganese 0.35‑1.60 %, which yields a tensile strength of 335‑600 MPa and a yield strength of 205‑345 MPa. These mechanical properties are typical for carbon‑steel pipe used in pressure‑bearing applications. End preparations can be plain, beveled or threaded, and surface protection options include three‑layer PE coating, oil‑based paint or hot galvanising. Such specifications meet the requirements of petroleum, chemical, power and ship‑building sectors.
The standard order minimum is five metric tonnes, though larger or smaller quantities can be arranged on request. Products are packed with plastic caps on both ends and bundled with steel straps, and the supplier can provide anti‑corrosion black painting as a special finish. Production capacity reaches 80 000 tonnes per year and typical delivery is within 25 days after payment, subject to final agreement on incoterms and payment terms.

Sourcing Seamless Steel Pipe from Hunan Prime Steel Pipe Co., Ltd. - China Import Guide
Before placing an order, verify the exact grade, outer diameter, wall‑thickness schedule and length required for your project. Request the latest mill test report and confirm that the pipe conforms to the relevant ASTM or API standard. If you need a special surface coating or anti‑corrosion treatment, clarify the specification and any additional cost with the supplier.
Discuss the preferred incoterm, such as FOB Changsha or CIF Shanghai, and agree on payment terms, typically a TT deposit followed by balance on document release. Shipping arrangements should consider the 5‑tonne minimum order and the possibility of container or bulk freight based on the total volume. Confirm the estimated lead time, which the supplier states as within 25 days after payment, and allow a buffer for customs clearance.
Arrange a third‑party inspection or request the supplier’s ISO 9001:2008 audit report to ensure quality compliance. Obtain a detailed packing list, material test certificates and, if required, a non‑destructive testing report for weld‑free seams. Maintaining proper documentation will facilitate smooth customs clearance and post‑delivery acceptance.
