What are Stainless Steel ERW Pipes?

Stainless Steel ERW (Electric Resistance Welded) Pipes are manufactured by rolling stainless steel coils into a cylindrical shape and joining the edges using high-frequency electric resistance welding. Unlike conventional welding methods, ERW does not require filler metal, resulting in a clean, strong, and uniform weld seam.

The welding process produces pipes with excellent dimensional accuracy, smooth internal surfaces, and high structural integrity. Stainless Steel ERW Pipes are widely used for transporting liquids, gases, steam, chemicals, and other industrial fluids where strength, corrosion resistance, and cost-effectiveness are essential.

These pipes are available in various grades, diameters, wall thicknesses, and finishes to meet diverse industrial requirements.
