This machine adopts advanced F.F technique, forming steadily, high quality and convenient change specification. It consists of rough forming and finishing forming. They can be suit to various specifications, thus it save the use of rollers to 70%--80%, which improve the forming efficiency, also reduce the investment and spare parts.
API406 Steel Tube Mill Advantage:
1. FF forming process save roller up to 60%.
2. Automatic adjustment, save roller changing time.
3. Homogeneous deformation of each stand, improve pipe quality.
4. Low defective product rate.
5. Siemens, Yaskawa, Allen-Bradley motor as option.
