Import Astm A179 Heat Exchanger Tube — Buy in Bulk from Supplier in China

This Astm a179 heat exchanger tube is a cold-drawn low-carbon steel seamless tube supplied by Suzhou Seamless Steel Tubeco Ltd. in China. It is delivered in annealed, normalized, or normalized and tempered conditions to meet thermal and mechanical demands in heat exchanger and condenser applications. The tubes undergo a full suite of inspections, including chemical composition checks, tensile and yield strength tests, elongation, flaring, flattening, hardness, and impact testing, as well as surface and dimension inspections, non-destructive testing, and hydrostatic testing to ensure structural integrity under pressure.

The material composition is low-carbon steel, a standard choice for ASTM A179 tubes due to its balance of strength, ductility, and thermal conductivity. Typical industry grades for such tubes include A179, with carbon content usually capped at 0.06-0.18% and manganese at 0.27-0.63%, delivering consistent performance in heat transfer systems. Surface treatments available from this supplier include oil-dip, varnish, passivation, phosphating, and shot blasting, which enhance corrosion resistance and prepare the tubes for specific operational environments.

These tubes are used in oil and gas, power generation, and chemical processing plants where efficient heat transfer is critical. Buyers typically source them in bulk for condenser and heat exchanger assemblies, with packaging options such as bundle or crate packing to suit long-distance shipping. The size range spans outer diameters of 17.2 to 76.2 mm and wall thicknesses from 1.6 to 10 mm, accommodating a wide array of system designs. For exact dimensions or custom requirements, confirm with Suzhou Seamless Steel Tubeco Ltd.

Suzhou Seamless Steel Tubeco Ltd. is based in Wangting town, Suzhou, Jiangsu Province, China, with its facility located at No.3, Xinhua Road, Xinhua Industrial Park. The company operates as an importer-tier supplier, specializing in seamless steel tubes for industrial applications, including heat exchanger and condenser systems. Its address and industrial park location indicate a focus on manufacturing and distribution within a dedicated industrial zone.

The supplier’s profile does not indicate a verified response rate or average response time, which suggests that direct communication may require additional follow-up. The trust tier is classified as harbor, a baseline level for suppliers on the platform. For buyers, this means due diligence is necessary to confirm capabilities, certifications, and production timelines before committing to an order.
