Video Specification The Pipe Inner Scarfing Remove Device is a vital component of the ERW tube mill line , designed to remove the inner weld bead formed during high-frequency welding. By accurately cutting and removing the internal bead, it ensures a smooth internal surface, improves coating quality, and enhances pipe performance in downstream applications such as fluid, gas, and structural use. Hebei AIS Machinery offers two models to suit different production needs: Mechanical Type and Pneumatic Type Inner Scarfing Devices. 1. Mechanical Type Inner Scarfing Device Description The Mechanical Type Inner Scarfing Device adopts a precision manual mechanical feed system to control the cutting head position inside the welded tube. It’s ideal for medium-speed ERW lines with fixed specifications, offering stable operation and long service life. Main Features Stable mechanical control for consistent cutting performance Manual adjustment of cutting depth and tool position Simple structure, low maintenance, easy installation No air or electrical power required Suitable for carbon steel and galvanized steel pipes Technical Range • Pipe OD: 20 – 165 mm • Wall Thickness: 0.8 – 5.0 mm • Line Speed: up to 60 m/min • Feed Control: Manual mechanical feed • Material: Carbon steel / Galvanized steel Applications Best for construction tube , furniture pipe , and general structural pipe production where pipe sizes remain stable. 2. Pneumatic Type Inner Scarfing Device Description The Pneumatic Type Inner Scarfing Device uses compressed air to drive the cutting head feed and retract mechanism automatically. It enables quick setup, higher precision, and improved safety—ideal for high-speed ERW tube mills or frequently changing production . Main Features Pneumatic automatic feed and retract system Quick tool positioning for size change Adjustable air pressure ensures consistent bead removal Smooth cutting and excellent surface finish Suitable for carbon steel and stainless steel pipes Technical Range • Pipe OD: 25 – 325 mm • Wall Thickness: 1.0 – 8.0 mm • Air Pressure: 0.5 – 0.8 MPa • Line Speed: up to 120 m/min • Feed Control: Pneumatic automatic feed & retract 1.Cutter, 2. support, 3. cylinder, 4.roller, 5. roller, 6. impeder,7. pull rod, 8. air source feeding, 9.plate Applications Recommended for API pipe , boiler tube , precision structure pipe , and high-speed welded pipe lines that require clean, uniform internal surfaces. 3. Comparison Between Mechanical and Pneumatic Types Feature Mechanical Type Pneumatic Type Drive System Manual mechanical feed Pneumatic automatic feed Operation Manual adjustment Automatic control Pipe OD Range 20–165 mm 25–325 mm Production Speed Medium (≤60 m/min) High (≤120 m/min) Setup Time Longer Quick changeover Maintenance Simple, low cost Slightly higher Automation Level Basic Advanced Recommended For Stable, fixed-size production High-speed, multi-size production 4. How to Choose the Right Device Choose Mechanical Type if: Production speed is moderate (below 60 m/min). Pipe sizes are fixed or rarely changed. You produce construction or furniture tubes. You prefer simple operation and low maintenance cost. Choose Pneumatic Type if: Line speed is high (up to 120 m/min). Pipe sizes change frequently. You produce precision or API pipes. You require automatic control and improved surface finish. 5. Advantages of AIS Inner Scarfing Systems High precision and stable cutting performance Improved internal surface quality and pipe roundness Longer tool life with carbide or HSS cutting heads Easy integration into existing ERW tube mills Customizable design according to line speed and pipe size range 6.
