Description of PERT pipe making machine: Process flow: Raw material--vacuum feeding--material dryness--single screw extruder--spiral mould--low-termeperature cooling calibrator, high level water tank--water cooler--DIP-in vacuum calibration tank--DIP-in cooling water tank--DIP-in cooling water tank--printer--belt haul-off--double winder--finished product inspecting&packing Salient features of PERT pipe: The high performance PE-RT pipe has been successfully used for many years in underfloor heating systems thanks to its outstanding properties. PE-RT pipes are increasingly replacing PE-X (cross linked polyethylene) on account of their enormous functional capacity. PE-RT pipes display an outstanding stability against stress corrosion cracking and have a very good creep strength. The pipe is also highly flexible and extremely easy to handle even at low temperatures.
