ERW377 high frequency longitudinal welded pipe production line / pipe making machine / tube mill is designed to produce welded pipes of 165mm-377mm in OD and 4.0mm-14.0mm in wall thickness, as well as corresponding square and rectangular pipe.
Advantage:
When producing round pipe, it can utilize ZTF forming technique
When producing square & rectangular tube, it can utilize directly square-square (DSS) technique
Products:
Architectural structure pipes, API pipes, tower footing tubes, automobile beam steel pipe and other products.
