Product Overview
Electric Resistance Welded (ERW) Steel Pipes offer a cost-effective, high-strength solution for fluid transport and structural systems. Manufactured with precision for consistent wall thickness and dimensional accuracy, our pipes are available in ½”–26″ (21.3–660 mm OD) and wall thicknesses of 1.0–17.5 mm, meeting API 5L PSL1/PSL2, ASTM A53, and EN 10219 standards.
