UPVC/PVC pipe production line/ UPVC/PVC pipe machine/ UPVC/PVC pipe machine UPVC/PVC Pipe Production Line/ UPVC/PVC Pipe Extrusion Line / UPVC/PVC Pipe Making Machine / plastic machinery The UPVC foam core pipe extrusion line can produce UPVC pipe, PVC foam pipe, PVC pipe with internal screw thread, PVC foam pipe with internal screw thread, PVC hollow wall pipe with internal screw thread. This kind of pipe features: smaller density 0.7-1 (while traditional pipe about 1.4). Noise reduced. It can reduce the noise and guide water flow. The ability of ventilate and drainage is increased. PVC foam pipe noise is 7-15DB lower than traditional PVC pipe. It is an alternative for construction tothe common pipe. The UPVC foam core pipe extrusion lineis mainly composed by: 1. Mixer 2. Feeding machine 3. Conical twin screw extruder 4. Mould 5. Calibration jacket & water spray vacuum calibration tank 6. Water cooling tank 7. Printer 8. Haul off machine 9. Cutter 10. Unloading stacker The UPVC foam core pipe extrusion line adopts co-extrusion die ensures high quality pipe. By equipping spiral grooved core-rod you can produce foam core pipe with internal screw thread and hollow wall pipe with internal screw thread. The UPVC foam core pipe extrusion line adopts vacuum cooling calibration tank. The tank is made of stainless steel. The pipe is calibrated precisely. The spray water cooling bath ensures fast cooling. The finished pipe surface is smooth and glossy. Haul off unit adopts two caterpillars. The haul off speed is controlled by frequency inverter. With control center, high automation, operate easily. The UPVC foam core pipe extrusion line also called UPVC foam core pipe extrusion line, PVC pipe extrusion line, PVC pipe production line, PVC pipe extrusion machine, PVC pipe extruder, PVC pipe producing machine, PVC pipe making machine, PVC pipe plant, UPVC pipe manufacturing machine, UPVC pipe machine, UPVC foam core pipe production plant, UPVC foam core pipe manufacturing plant, UPVC pipe extruder, etc.
