ERW / HFW Pipe
"Efficiency & Precision"
Electric Resistance Welded / High Frequency Welded. The standard for cost-effective piping.
"The High-Speed Highway"
Just as highways move traffic efficiently, ERW pipes are mass-produced with high precision to move fluids across cities. They offer the best balance between performance and cost.
Produced by cold-forming a steel coil into a cylinder and welding the seam using electrical resistance. HFW is a higher quality variant often used for energy pipelines (Line Pipe). It is widely used for city gas lines, water distribution, and structural columns.
