ERW Pipes & Tubes (Electric Resistance Welded)
ERW pipes and tubes are manufactured by feeding a rectangular steel strip through a rolling machine that gradually curls the long edges upward toward each other, forming a round (cylindrical) shape. In the ERW process, high-frequency electrical current is passed between the two edges, causing them to heat, melt, and fuse together — creating a longitudinal weld along the full length of the pipe.
A key advantage of ERW pipe is that no filler (fusion) metal is used, and the weld seam is typically smooth and uniform, often difficult to see or feel.
Modern High-Frequency ERW Technology
Welded pipe manufacturing has advanced significantly over the years. One of the most important improvements was the industry-wide shift to high-frequency electric current welding. Earlier low-frequency ERW weld seams (common prior to the 1970s) were generally more susceptible to corrosion and seam-related failures compared to modern high-frequency ERW.
In manufacturing ERW steel pipes and tubing, we use high-quality steel such as continuous-cast, fully-killed, control-rolled, fine-grain, low-carbon material — supporting consistent welding, performance, and reliability.
High-performance ERW pipes and tubes are known for:
- High strength
- Good corrosion resistance
- High deformability
- Strong toughness and durability
Applications
ERW steel pipes and tubes are widely used for:
- General engineering and fabrication
- Fencing
- Scaffolding
- Line pipe applications
- Structural and industrial use (based on specification)
