ERW273 high frequency longitudinal welded pipe production line / pipe making machine / tube mill is designed to produce welded pipes of 114mm-273mm in OD and 3.0mm-10.0mm 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
