An ERW (Electric Resistance Welded) Tube Mill is an integrated production line that forms flat steel strip into round or shaped tubes through cold-forming rolls before welding them longitudinally by electric resistance welding pressure—without filler metal. A modern ERW tube mill line includes uncoilers → levelers → forming → welding → sizing → cut-off → straightening → finishing sections—all controlled by PLC & HMI systems.
Key Advantages of ERW Tube Mill Machine
• High-speed production (up to 120 m/min)
• Clean weld seam—no filler material
• Precise OD & wall thickness tolerance
• Versatile profiles (round/square/rectangular)
• Cost-effective & energy-saving

1. Uncoiler & strip accumulator
2. Roll forming stands (horizontal & vertical)
3. HF welder (solid-state or IGBT)
4. Sizing & turks-head rolls
5. Flying cold saw / shear
6. Run-out table & stacking system
• Automotive chassis & exhaust pipes
• Structural scaffolding & fencing
• Furniture tubing & mechanical parts
• API oil & gas line pipes
