ERW 32 Welded Pipe Production Line

Brief Introduction
ERW32 high frequency longitudinal welded pipe production line / pipe making machine / tube forming machine is designed to produce welded pipes of 10mm to 32mm in OD and 0.3mm to 2.0mm in wall thickness, as well as corresponding square and rectangle tube.

Advantages
1. In the preparation process, high frequency straight seam welded pipe mill mainly developed the volume type loop hoppers.
2. In the aspect of forming unit, this welded pipe making machine developed double wire forming.
3. The structure of forming unit developed part of the vertical roll group, the small row roller straight shape and vertical roll shape.
4. In the operating line, high frequency straight seam welded pipe mill set up online continuous flow inspection and ultrasonic inspection.
5. In the steel tube heat treatment technology, it developed online welded heat treatment, off-line frequency induction heat treatment and continuous bright annealing heat treatment.

This high frequency longitudinal welded pipe production line, or simply ERW pipe making machine, is designed to produce welded pipes of 10mm-32mm in OD and 0.3mm-2.0mm in wall thickness, as well as corresponding square and rectangular pipes.
