PE/PPR DUAL PIPE EXTRUSION LINE Our PE/PPR dual pipe extrusion can process wide range of material, including HDPE, LDPE, PP, PPR, PPH, PPB, MPP, PERT, etc. Usually, dual pipe size ranges from minimum 16mm to 63mm with single layer or multi-layer. Each pipe has it own control to make operation easier, faster and stable. Single Screw Extruder Based on 33:1 L/D ratio for screw design, we have developed 38:1 L/D ratio. 38:1 ratio has advantage of 100% plasticization, increase output capacity by 30%, reduce power consumption up to 30% and reach almost linear extrusion performance. Extrusion Die Head Extrusion die head apply spiral structure, each material flow channel is placed evenly. Die head structure is compact and also provide stable pressure, always from 19 to 20Mpa. Under this pressure, pipe quality is good and very little effect on the output capacity. Can produce single layer or multi-layer pipe. Vacuum Tank We use double-chamber structure. First chamber is in short length, to ensure very strong cooling and vacuum function. As calibrator is placed in the front of first chamber and pipe shape is formed mainly by calibrator, this design can ensure quick and better forming of pipe. Haul off unit According to different pipe sizes and thickness, our company will customize traction speed, number of claws, effective traction length. To ensure match pipe extrusion speed and forming speed, avoid deformation of pipe during traction. Cutter Controlled by Siemens PLC, working together with haul off unit to have precise cutting. Multi-feed-in actions for the accomplishment of one cutting process (prevent from blade or saw stuck for thick pipe and face of pipe is smooth).
