What is ERW in Steel Pipe?
Electric Resistance Welding, or ERW, shapes modern steel pipe production. We use high-frequency electric currents to join steel edges. This process creates strong, uniform welds without extra filler materials.
How Does ERW Work?
You pass a steel strip through forming rollers. Then you shape it into a tubular form. High-frequency currents heat the steel edges. Pressure welds the edges together instantly. The result becomes a seamless-looking pipe.
Why Choose ERW Steel Pipe?
ERW steel pipe offers many clear benefits:
1.Precise dimensions – Machines control every step tightly.
2.Smooth surface – No internal weld flash to slow fluids.
3.Cost efficiency – Lower energy use than seamless methods.
4.Consistent quality – Automated welding ensures reliability.
5.Thin to thick walls – We produce 0.5mm up to 80mm thickness.
Manufacturers prefer ERW for structural and fluid applications. Construction projects rely on its uniform strength. Automotive frames use its lightweight yet rigid properties.
Our ERW Production Capacity
We operate 65 ERW and HFW pipe production lines. These lines run 24 hours daily for rapid delivery. Our advanced JCOE and LSAWA processes handle larger diameters. We produce square pipes from 10x10x0.5mm to 1000x1000x60mm. Rectangular sizes reach 800x1200x60mm. Circular pipes range from Ø10.3mm to 2032mm.

Premium Raw Materials for Superior Pipes
Sourcing matters for final product quality. We buy steel coils from state-owned mills only. HBIS, Baosteel, and TPCO supply our raw materials. These mills produce consistent, clean steel chemistry. No impurities weaken our welds or walls.
Advanced Manufacturing Processes
Beyond ERW, we master several pipe-making technologies:
① HFW – High-frequency welding for thinner walls
② LSAW – Longitudinal submerged arc for large diameters
③ SSAW – Spiral welding for extra-long lengths
④ Seamless – Hot-rolled for extreme pressure applications
⑤ Hot and cold forming – Shape versatility for special orders
Black Square Tube and Galvanized Options
Our black square tube serves structural frameworks perfectly. Fences, scaffolding, and machinery guards use this product. We also produce galvanized square and rectangular pipes. Hot-dip galvanizing adds corrosion resistance. Zinc coatings extend service life in outdoor settings.
We run 26 galvanizing lines for fast turnaround. Ten pre-galvanized lines handle smaller orders efficiently. Eight PV support lines serve solar mounting structures. This diversity meets every construction need.
Commitment to Sustainable Manufacturing
Green production drives our industry leadership. We expand production chains with eco-friendly methods. Enhanced industrial clusters reduce transport emissions. Large-scale operations lower per-unit energy use. We promote structural steel pipes for sustainable global development.
