ERW140 high frequency longitudinal welded pipe production line / pipe making machine / tube mill is designed to produce welded pipes of 60mm-140mm in OD and 2.0mm-5.0mm in wall thickness, as well as corresponding square and rectangular pipe.
Products: architectural structure tubes, low-pressure liquid tubes, coal transmission belt tubes, drive shaft tubes, guardrail tubes, tower footing tubes, automobile beam steel tube and other products.
Advantage:
When producing round pipe, it can utilize ZTF forming technique
When producing square & rectangular tube, it can utilize directly square-square (DSS) technique
