Product description
ERW406x8.0mm welded pipe production line
The ERW406mm High-Frequency Longitudinal Welded Pipe Production Line is a robust and efficient manufacturing system for producing steel pipes with outer diameters of φ165 to φ406mm and wall thicknesses ranging from 3.0mm to 8.0mm. This advanced line integrates the FFX (Flexible Forming Extended) process, which enhances productivity, precision, and flexibility.

The FFX (Flexible Forming Extended) process is an advanced manufacturing method that enhances efficiency and flexibility in tube production. By using shared rolls in the rough forming section, it reduces tooling requirements, changeover time, and costs. Below is the detailed step-by-step production workflow:
Loading trolley, uncoiling → straightening head → clamping and leveling → automatic shear butt welding → looper → forming, high-frequency welding, deburring, cooling, sizing, rough straightening → milling, sawing and sizing → inspection and collection → packaging → warehousing
