Welded Pipe Making Machinery ERW140

ERW140 H.F. Straight Welded Pipe Production Line

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.

Equipment advantages：
√ ZTF forming process save roller up to 60%
√ With direct square forming technology, one set of roller can produce all pipe sizes
√ Electric control and automatic adjustment, high precision,high roller change speed
