Import Bsi Standard Seamless Carbon Steel Tube — Buy in wholesale FOB from Supplier in China

The BSI Standard Seamless Carbon Steel Tube from Shandong Wan Steel Import And Export Co., Ltd. is a hot-rolled, cold-rolled, and cold-drawn seamless tubular product manufactured to British Standards Institution requirements. Outer diameter spans 14 mm to 630 mm, with wall thickness from 2.5 mm to 35 mm, covering a size range suitable for boiler, pressure vessel, structural, and mechanical engineering applications. Standard commercial lengths are 5.8 m, 6 m, 11.8 m, and 12 m, with random lengths or cut-to-size service available for export orders. The material matrix includes carbon and alloy grades under GB/T8162, GB/T8163, GB/T3087, GB/T5310, GB/T9948, GB6479, ASME SA213, API 5L, ASTM A106, ASTM A53, and DIN 17175, among others, giving buyers broad specification-matching capability.

Manufacturing routes cover hot rolling for thicker walls and larger diameters, cold rolling for improved dimensional tolerance and surface finish, and cold drawing for tight OD/WT control and higher strength. Delivery conditions include normalized (N), annealed (A), tempered (T), quenched (Q), and combined treatments such as N+T or Q+T, each altering the microstructure and mechanical properties for specific service environments. Ends are supplied flat, bevelled, or threaded, with plastic caps or steel rings for corrosion protection during transit. The seamless construction eliminates the weld seam, offering uniform circumferential strength and reduced risk of failure under cyclic pressure or thermal stress compared with ERW alternatives.

Typical buyers include oil and gas pipeline contractors, power plant fabricators, petrochemical constructors, and general structural steel distributors. The wide grade and standard coverage means procurement teams can source tubes for diverse pressure, temperature, and corrosion regimes from a single supplier, provided certificates of conformity and mill test reports match the project specification. The supplier's location in Taishan Steel Industry Park, Taian, Shandong, places it near raw material mills and port access via Qingdao or Tianjin, though buyers should confirm the specific loading port and inland logistics arrangement for their shipment.

Shandong Wan Steel Import And Export Co., Ltd. operates from No.19 Road in Taishan Steel Industry Park, Taian, Shandong Province, China. This location sits within one of China's densest clusters of steel production and tube finishing facilities, with access to slab, billet, and hot-rolled coil feedstock from integrated mills. The company's name and address suggest it functions as a manufacturer-exporter or a tightly integrated trading arm of a mill group, though the profile does not confirm captive melting or rolling capacity. The trust tier is harbor, with a 0.00% response rate, indicating limited active engagement through the portal and a need for direct contact.

The supplier profile does not disclose year of establishment, registered capital, annual output, workforce size, ISO 9001 certification status, or major project references. No client list, export volume, or third-party audit credentials are presented. Buyers should therefore request business registration documents, quality management system certificates, and mill test report samples before committing to large orders. The breadth of standards and grades listed (spanning Chinese national, American, European, and Russian norms) implies either substantial rolling versatility or trading access to multiple mills, which should be clarified during technical negotiation.
