Electric Resistance Welded (ERW) tubular products in circular, square or rectangular and Spiral Submerged-Arc Welding (SSAW) steel pipes

Utilizing high-frequency welding technology, we produce Electric Resistance Welded (ERW) pipes with a consistent, high-strength weld and no added fusion material. The resulting smooth finish and precise dimensions ensure maximum reliability for structural use and fluid transport. Produced through a precision helical forming and double-sided submerged arc welding process, our Spiral Submerged Arc Welding (SSAW) pipes deliver reliable performance for critical fluid conveyance and structural projects. The spiral seam construction provides enhanced flexibility in diameter and wall thickness while ensuring 100% weld integrity through nondestructive inspection.

Our pipes are manufactured from a variety of high-quality raw materials, including hot-rolled, cold-rolled, and pre-galvanized (pre-zinc) steel coils. These materials are precision-processed through roll forming and advanced welding techniques. This ensures a consistently strong weld bond, enhancing both the structural integrity and uniformity of the pipes to meet the demands of a wide range of applications.

Key features:

• Our pipes are manufactured using High-Frequency Electric Resistance Welding (ERW) and Spiral Submerged Arc Welding (SSAW), ensuring a consistently high-strength and uniform seam
• Manufactured from high-quality steel coils, precision-slit to the required widths to ensure exact dimensional specifications
• Available in an extensive range of diameters and wall thicknesses to accommodate diverse engineering and industrial applications
• The smooth internal finish ensures low frictional resistance and highly efficient fluid conveyance across all applications
• Adheres to tight dimensional tolerances and ensures structural uniformity, providing reliable performance for both high-pressure and structural applications.
