The ST80 Mechanical Structure Tube Mill is a heavy-duty production line designed for high-strength applications. It produces welded steel tubes with diameters from Φ89 to Φ159 mm and wall thicknesses from 2.0 to 5.0 mm, ensuring excellent structural integrity, dimensional accuracy, and durability under high loads and dynamic stresses. Featuring high-frequency or laser welding, precision forming, and advanced surface treatment, the ST80 delivers reliable, industrial-grade output at speeds up to 6 m/min-ideal for manufacturers of structural and mechanical components.
Key Technologies & Advantages
High-Precision Forming
Ensures dimensional accuracy and consistent tube shape.
Strong Welding Performance
TIG/laser welding for durable, high-integrity seams.
Smart Automation
PLC + HMI control for stable, real-time operation.
Energy-Efficient Design
Reduces power consumption by up to 25%.
Structural Tube Production Process
Uncoiling: Steel coil is fed into the machine.
Forming: Strip is shaped into a round tube via precision rolls.
Welding: HF/TIG/Laser creates a seamless joint.
Weld Grinding: Internal and external weld beads removed.
Sizing & Straightening: Final dimensions achieved.
Cutting: Circular, band, or laser saw cuts tubes to length.
Output: Finished tubes collected for inspection or shipment.
