PE pipe extrusion line is mainly used for producing water supply pipe and gas supply pipe. We have introduced highly-efficient extruder, sizing system, water lubrication and cooling system, to make it competent in guaranteeing the stability of HDPE pipes' dimension and roundness. Both the extruder and tractor are equipped with high-quality speed controller to realize high stability, precision and reliability. The whole pipe extrusion line is intelligently controlled by a PLC system. With a human-machine interface, all of the parameters can be set through the touch screen easily.
