product description

This high frequency welded pipe cold roll forming machine is a fully automatic integrated tube mill production line, specially engineered for continuous cold forming, high-frequency induction welding, sizing, straightening and cutting of carbon steel, galvanized steel, stainless steel strips to produce round, square, rectangular and special-shaped welded pipes. Adopting mature cold roll forming technology paired with high-frequency solid-state welding system, the whole line realizes one-stop forming and welding, stable operation, high production efficiency and low energy consumption, widely applied in construction, pipeline transportation, furniture, automotive, agricultural greenhouse and machinery manufacturing industries.

Main Working Flow

Strip Uncoiling → Strip Leveling → Edge Trimming → Continuous Cold Roll Forming → High Frequency Induction Welding → Weld Bead Scarfing → Online Cooling → Sizing & Shaping → Straightening → Flying Saw Cutting → Finished Pipe Collection All processes run automatically under PLC centralized control, reducing manual intervention and guaranteeing consistent pipe dimensional accuracy.

Core Advantages

1. Integrated Cold Forming & HF Welding Design Uniform cold roll forming stands with thick cast iron base, rigid forming frame, high-precision alloy forming rollers. The high-frequency welding unit delivers fast, firm welding seams with minimal deformation, no oxidation crack inside welds.
2. High Precision & Stable Output All forming rollers are CNC machined with chromium plating treatment for long service life. Adjustable forming stations support quick switch between different pipe specifications, tolerance control within ±0.1mm for pipe outer diameter and wall thickness.
3. Energy-Saving High Frequency Welding System Solid-state HF welder features high power conversion efficiency, less heat loss, lower electricity cost compared with traditional tube welding equipment; rapid heating shortens production cycle.
4. Full Automatic PLC Intelligent Control Equipped with touch screen operation panel, supports parameter memory, fault self-diagnosis, automatic length counting and flying saw fixed-length cutting. Real-time monitoring of forming speed, welding current and temperature.
5. Durable Heavy-Duty Structure Whole machine base uses thick steel plate welded box structure with vibration elimination annealing treatment, effectively resisting deformation under long-time high-speed operation. All transmission parts adopt hardened gears and heavy-duty bearings for extended service lifespan.
6. Certified Safe & Reliable Performance Comply with CE and SGS industrial production standards, complete safety protection covers, emergency stop device, overload protection system to avoid production accidents.
