406mm FFX forming machine
The 406mm FFX technology tube mill is designed for the efficient production of large-diameter high-frequency welded steel pipes. With advanced FFX forming technology, the line provides stable forming performance, high pipe quality, and convenient specification changeover for manufacturers producing round pipes from Φ219mm to Φ406mm.
This FFX tube mill line is suitable for carbon steel pipe production with a thickness range of 3mm to 12.7mm. It is widely used for producing structural pipes, construction pipes, industrial pipelines, and pipes for oil, gas, energy, and general engineering applications.
Key Advantages of the 406mm FFX forming machine
Advanced FFX Rough Forming Technology
The rough forming section adopts advanced FFX technology to ensure stable strip forming and consistent pipe shape. This helps improve finished pipe quality and reduce forming defects during large-diameter pipe production.
Wide Pipe Diameter Range
The line can produce round pipes from Φ219mm to Φ406mm, making it suitable for manufacturers who need one production line to cover multiple medium and large pipe specifications.
Quick Specification Changeover
The rough forming section can adapt to different pipe sizes, while the fin-pass and sizing sections can use quick-change design. This helps save roller change time, reduce downtime, and improve production efficiency.
Stable High-Frequency Welding
The 406mm FFX tube mill adopts solid-state high-frequency welding technology. It is suitable for continuous welded pipe production and helps ensure stable weld quality for industrial pipe applications.
High Automation and Reliable Control
The production line adopts a PLC control system, and the AC motor uses frequency conversion adjustment. This improves operating accuracy, speed control, and overall line stability during long-term continuous production.
High Annual Production Capacity
With a production capacity of 100,000–140,000 tons per year, the 406mm FFX technology tube mill is suitable for pipe manufacturers with high-volume production requirements.
