ERW steel pipes from United Steel Industry Co., Ltd are electric resistance welded tubes made from carbon steel grades Q195, Q235, Q345, and their European equivalents S235, S275, S355. These pipes conform to ASTM A53, API 5L, and ISO 65 standards and are available in outer diameters from 21.3mm to 508mm with wall thicknesses between 2mm and 20mm. The product is designed for structural, water, and gas transmission applications where mechanical strength and weldability are essential.
The pipes are supplied with square, beveled, or threaded ends, and surface finishes include black, hot-dip galvanized, electro-galvanized, or coated with coal tar epoxy, fusion bonded epoxy, or 3-layer polyethylene. These coatings enhance corrosion resistance for outdoor or buried installations. The manufacturing process ensures consistent weld quality, and the material composition supports cold bending and threading without cracking.
These pipes are sourced by civil engineering firms, pipeline contractors, and industrial manufacturers for infrastructure projects, water distribution networks, and structural frameworks. Trade is conducted in containerized shipments with bundles weighing up to 2,000kg, secured with steel strips and waterproof wrapping. Buyers should confirm end preparation, coating type, and testing protocols before ordering, as these vary by order specification.

Verify the exact material grade (Q235 vs S355), wall thickness tolerance, and end preparation before ordering. Request mill test reports for chemical composition and mechanical properties, especially if the pipes will be welded or subjected to stress. Confirm that all coatings are applied uniformly and that NDT reports are available for each batch.
Logistics are typically FOB or CIF from major Chinese ports. Lead time is not stated but generally ranges from 20 to 40 days depending on coating and testing requirements. Packaging uses hexagonal bundles up to 2,000kg with waterproof protection. Buyers must confirm Incoterms, container loading method, and insurance coverage to avoid liability gaps.
Inspect for surface defects, coating uniformity, and weld seam integrity upon arrival. Use a thickness gauge to verify wall dimensions and a magnet to detect galvanized coating. Request a certificate of conformity and packing list matching the shipment. For coated pipes, perform adhesion tests using tape pull or holiday detection to ensure long-term corrosion protection.
