HDPE/PP Dual-layer/Three-layer Pipe Extrusion Line

Adopting two or three extruders and their downstream equipment, the line can be used to produce two or three layer HDPE or PP pipes. With the middle layer as complete recycled material, and the outer layer coating with virgin, it can save you more than 50% material cost. The final pipes can be used as telecommunication pipes, transport of fluids under pressure with diameters of 32mm to 63mm. The thickness of the external layer is at least 20%, preferably 25 to 35 % of the total pipe thickness. PE special high-efficiency single screw extruder ensuring even and stable plasticization Bush structure for barrel feeding part Specially-designed spiral co-extrusion mould for dual layer or three layer PE pipe. High torsion gearbox, strong hardness and high smoothness gears. PLC controlling system for selection to improve the automatic control standard. High-precision temperature controller and particularly esigned air fans.
