Import Astm A106/Astm A53 Gr.B Carbonsteelseamless Pipe — Buy in Bulk from Supplier in China

The ASTM A106 and ASTM A53 Gr.B seamless carbon steel pipe from Cangzhou Zhongrun Steel Tube Co., Ltd. is a cold-drawn and hot-rolled product designed for high-pressure and high-temperature fluid transport in oil and gas, chemical and power generation sectors. It carries a carbon content of 0.30% by weight, contributing to its tensile strength and resistance to corrosion. The pipe is delivered with a maximum weight tolerance of ±12.5%, ensuring consistency in load-bearing performance and dimensional accuracy for industrial installations.

Manufactured to ASTM specifications, this seamless pipe is produced without longitudinal welds, eliminating weak points and enhancing structural integrity under stress. Gr.B denotes a higher yield strength compared to Gr.A, making it suitable for applications where mechanical robustness is critical. The material is typically supplied in standard lengths of 5.8m, 6m, 11.8m or 12m, with outer diameters ranging from 1/2 inch to 24 inches as standard for this grade. Surface finishes are usually black, galvanised or bare, depending on the end use and customer requirement.

Common buyers include contractors in petrochemical processing, municipal water supply systems and structural engineering projects. The pipe supports fluids such as steam, water and natural gas, and is compatible with flanges, fittings and valves designed for ASTM A106/A53 standards. For bulk procurement, packaging is typically in bundles with steel strips and waterproof covers, and the supplier offers FOB and CIF shipping terms. Buyers should confirm the exact length, end finish and testing requirements before placing an order.

Cangzhou Zhongrun Steel Tube Co., Ltd. is based in Xinhua District, Cangzhou, Hebei Province, China, with its registered address at No.10 Of East Road, North Ring. The company operates as an imported-tier supplier, specialising in the production and export of carbon steel seamless pipes for industrial applications. Its location in Hebei, a key steel manufacturing hub, provides access to raw materials and logistics infrastructure for efficient production and distribution.

The supplier’s profile indicates a harbor trust tier, reflecting a verified operational presence. However, the response rate and average response hours are currently not available, suggesting buyers may need to initiate contact directly for timely inquiries. The company focuses on delivering products that meet international standards, as evidenced by its adherence to ASTM specifications for seamless pipes.
