ERW89 H.F. Straight Welded Pipe Production Line

ERW89 high frequency longitudinal welded pipe production line / pipe making machine / tube mill is designed to produce welded pipes of 42mm-89mm in OD and 1.5mm-4.5mm in wall thickness, as well as corresponding square and rectangular pipe.   We can design and manufacture pipe making machine according to customers’ requirements.

Products Details

High frequency welded pipe production line is mainly used for continuous production of straight seam welded pipe. It adopts high-frequency induction welding, which can not only produce round pipe but also corresponding square pipe and special-shaped pipes. The high-frequency pipe welding machine is mainly used for the production of various iron pipes, construction pipes, structural pipes, water pipes, oil pipes, API Pipes, and so on.
