With vast experience in the HDPE single and multi layer pipe extrusion field, our company made a 75-315mm HDPE pipe extrusion machine line. We adopt 160kw motor, Flender gearbox, Siemens PLC control system. For the multi layer HDPR pipe, inner and outer layer used virgin material and the medium layer used recycling material. It is a good way to save the capital of the raw material.
