Automatic Decoiler with Hold-Down Arm
The production line adopts a fully automatic decoiler equipped with a hold-down arm to prevent coil loosening and material scattering during feeding.
Advantages include:
Stable coil feeding
Improved operator safety
Reduced downtime
Smooth strip entry
The automatic rotating and turning system helps improve strip alignment and feeding efficiency.
Automatic Shear and Butt Welding System
The automatic shear and butt welding machine performs strip cutting and welding automatically when changing coils.
Benefits:
This system is especially suitable for high-speed tube manufacturing lines.
Spiral Accumulator for Continuous Production
The spiral accumulator stores steel strip during coil replacement to keep the tube mill running continuously.
Key features:
Stable strip storage
Reduced production interruption
Suitable for high-speed production
Compact structure with large storage capacity
Compared with traditional cage loops, the spiral accumulator provides smoother strip operation and better production stability.
400KW Solid State High Frequency Welder
The line is equipped with a 400KW solid state high frequency welding system for efficient ERW welding.
Advantages:
The welding system supports various steel pipe sizes and thicknesses.
Quick Change Forming System with Pneumatic Shaft Disengagement
The main machine adopts a quick-change forming structure with pneumatic shaft disengagement.
Benefits:
Faster roller replacement
Reduced labor intensity
Shorter production changeover time
Improved production flexibility
This design is ideal for manufacturers producing multiple pipe sizes.
Cold Flying Saw Cutting System
The cold saw cutting system ensures high precision and burr-free pipe cutting.
Advantages:
Compared with friction saw cutting, cold saw cutting provides better cutting quality and cleaner pipe ends.
