The global benchmark for industrial square tube production, combining high-frequency induction welding with modular precision roll forming for maximum structural integrity.
Setting new standards for ERW pipe production with integrated automation.
◆ As a leader in general equipment manufacturing, our square tube roll forming machine provides unrivaled precision for ERW pipes with diameters from Φ114mm to Φ325mm. By integrating high-power HF induction welding, we ensure stable performance even with thick-wall materials.
◆ Our square tube roll forming machine leverages a modular design and a flexible roll tooling system that drastically reduces downtime. With PLC centralized control and HMI touch screens, operators achieve seamless transitions between pipe sizes.
Three foundational advantages that ensure maximum productivity and structural precision.
Advanced HF induction technology for thick-wall structural tubes.
Seamless transition from round to square profiles.
Centralized automation for maximum line consistency.
Quantifying the performance gains of automated roll forming over traditional methods.
Comprehensive engineering data for our standard industrial line.
