Import Erw Steel Pipe — Buy in Bulk from Supplier in China

ERW steel pipes from Shanxi Guolian Pipe Industry Group are produced using electric resistance welding of cold-rolled steel strips, resulting in longitudinal welds with controlled heat input for consistent mechanical properties. These pipes are manufactured in outer diameters from 21.3mm to 610mm and wall thicknesses from 1.5mm to 16mm, with standard lengths of 5.8m to 12m. The material is sourced to meet ASTM A53 Grade B, API 5L B, and GB/T 9711.1 standards, with surface options including black, hot-dip galvanized, and epoxy-coated finishes.

The manufacturing process adheres to continuous coil feeding and high-frequency induction welding, ensuring minimal heat-affected zones. Typical mechanical properties include a minimum yield strength of 240MPa and tensile strength of 415MPa for Grade B. Coatings are applied after welding and pass inspection for adhesion and thickness. Packaging includes plastic end plugs, waterproof wrapping, and steel-strapped bundles of up to 2,500kg. The product is not seamless and is intended for low-to-medium pressure fluid transport.

This pipe is commonly purchased by engineering firms in infrastructure, water distribution, and agricultural irrigation projects across Central Asia and Eastern Europe. Buyers in regions with limited access to seamless pipe supply use these as economical alternatives for non-critical pipelines. Trade terms are usually FOB or CFR from Tianjin or Xingang ports. MOQs are flexible, but full container loads are preferred for cost efficiency. Buyers should confirm whether the pipe is produced for PSL1 or PSL2 compliance if used in regulated environments.
