Precision Tube Mill Machine for Round Square Rectangular Pipes 200x200mm

This high-precision ERW219mm tube mill machine manufactures welded steel pipes with diameters from Φ89mm to Φ219mm (wall thickness 2.0-8.0mm) and square pipes from 80*80mm to 200*200mm. Combining international and domestic pipe-making technologies, our innovative production line delivers both economical and practical solutions.

• Uncoils and flattens steel coils into strips
• Forms strips into round pipe shape using precision rollers
• Welds tubes with high frequency solid state welder
• Sizes tubes to exact specifications
• Cuts to precise lengths (4-12m) with ±1mm accuracy

• Ultra-high precision: Roller jumps ≤0.01mm, frame clearance ≤0.02mm, diameter error ≤0.08mm
• Japanese technology: Meets strict international accuracy requirements
• Precision adjustment: Worm gear system with schedulable control
• 3D adjustable scraping: ±20° rotation capability
• Turkish head forming: Reduces mold weight while ensuring stable forming and uniform R angles
• Vibration reduction: Nylon damping blocks minimize shaft and bearing impact
