High Frequency Welding API ERW Steel Tube Production Mill Line Pipe Making Machine

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

• Produces longitudinal weld seam tubes and pipes from steel strips of specific widths
• Process begins with uncoiling and flattening slitted steel coils into strips
• Forming machine with roller tooling shapes strips into round pipes
• High frequency solid state welder joins the seams in the weld box
• Sizing machine forms tubes to final dimensions before cutting and bundling

• High precision: Level roller jumps 0.01, frame/slide clearance ≤0.02, frame verticality ≤0.05, frame parallelism ≤0.1, diameter/roundness error ≤0.08
• Japanese technology meets high accuracy requirements for international clients
• Worm gear adjustment provides precise, energy-efficient operation
• 3D adjustable scraping system with ±20° rotation capability
• Turkish head push square forming reduces mold weight while maintaining stability and uniform R angles
• Nylon damping blocks minimize impact on shafts and bearings
