10inch 273mm ERW Pipe Making Machine

Applicable pipe types include: structural pipes, fluid pipes, pressure pipes, pile pipes, and general-purpose steel tubes.

2.  BASIC DESIGN DATA

Design of the proposed line is based on following specification:

Equipment Advantages 

• Stable Construction: Heavy-duty welded frame ensures long-term durability

• Intelligent Control: Full PLC control with alarms, diagnostics, and remote support

• Quick Changeover: Supports multiple profiles (round, square, rectangular)

• Excellent Weld Quality: Precision-matched HF system ensures solid welds

• Energy Efficient: Inverter-controlled drives reduce power consumption by over 20%

• Modular Design: Optional upgrades for stackers, cutting units, inspection systems

Welding Principle  

Using high-frequency induction heating, the strip edges are rapidly heated to a plastic state, then squeezed together by pressure rollers to form a continuous weld.

• Advantages: Smooth weld seam, small heat-affected zone, no filler material needed

• Key Parameters: HF power adjustment, coil alignment, squeeze pressure

• Burr Removal: Optional internal and external scarfing improves final product finish

 Operating Procedure 

1. Ensure all systems (electric, hydraulic, water) are operational

2. Load coil → Shear & weld → Accumulate strip → Forming & welding → Cooling → Sizing → Cutting

3. Check roll wear, blade sharpness, and induction coil daily

4. Monitor welding temperature, strip tension, and sizing output via HMI

5. Shutdown sequence: stop line → cut power → close water/air systems in order

Selection Advice for Customers

1.  

   • Define main product specs (e.g., Φ168, Φ219) when configuring forming stations

   • Wall thickness range determines required HF power and saw type

   • Export customers should specify voltage, control language, and certification needs (e.g., CE)

   • Optional upgrades: online seam inspection, laser OD measurement, automatic stacking systems
