Our carbon steel welded pipes are manufactured using advanced ERW (Electric Resistance Welding) or LSAW (Longitudinal Submerged Arc Welding) technology. The production process incorporates precision forming systems with automatic seam tracking, in-line heat treatment for stress relief, automated ultrasonic testing for weld integrity, and computer-controlled cutting to length. These integrated measures ensure strict wall thickness tolerance of ±10% and consistent product quality.
