ERW Pipe Welding Machine 32-114mm Diameter DC Speed Control

This advanced production line manufactures welded steel pipes from Φ32mm-Φ140mm with wall thickness of 1.0mm-5.0mm, capable of producing square pipes from 25×25mm to 110×110mm. Combining international and domestic pipe making technologies, our innovative design offers both economic and practical advantages.

The complete line consists of three main sections:

• Entry Section: Uncoiling, flattening, and preparing steel strips
• Forming & Welding Section: Cold forming, high-frequency welding, and sizing
• Cutting & Delivery: Precision cutting and final product handling

• Exceptional precision with level roller jumps ≤0.01mm and diameter/roundness error ≤0.08mm
• Japanese technology implementation for high accuracy requirements
• Worm gear adjustment system for precise, energy-efficient operation
• 3D adjustable scraping system with ±20° rotation capability
• Turkish head push square forming for stable operation and uniform angles
