6, low-temperature impact resistance: Low temperature brittleness of polyethylene is very low, can be safely used within a temperature range of -60-60 ℃. Construction in winter, due to material impact resistance, and does not occur tube embrittlement. 7, good resistance to stress cracking resistance: HDPE has a low notch sensitivity, high shear strength and excellent resistance to scratches capacity, resistance to environmental stress cracking resistance is also very prominent. 8, good chemical resistance: HDPE pipe corrosion resistant variety of chemical media, the presence of chemicals in the soil will not cause any degradation of the pipeline. Polyethylene is the electrical insulator, it will not rot, rust or electrochemical corrosion; moreover it will not promote algae, bacteria or fungal growth. 9, good flexibility: Flexible HDPE pipe makes it easy to bend, around obstacles on the project can PPR pipe equipment Which direction by changing the way the pipeline? In many cases, the flexible pipe fittings to reduce consumption and lower installation costs. 10, a small flow resistance: HDPE pipe has a smooth inner surface, the Manning coefficient of 0.009. Smooth performance and non-adhesion properties ensure HDPE pipe has a higher than traditional pipe transmission capacity, but also reduces the pressure loss and water consumption pipeline. After seeing more than ten PPR pipe equipment manufacturers, feeling PE pipe still has a lot of advantages, like more PE pipe information, please consult our day Qingdao letter Thai Plastic Machinery Co., Ltd. recently by absorbing advanced technology and research and development new pipe PPR pipe production line equipment suppliers, suitable for PE, high speed PP, PB PPR pipe equipment, PERT, ABS and other raw materials extrusion. The production line has a beautiful appearance, high degree of automation and production stability and reliability. The production line by the majority of customers, is to replace the import of advanced production line the best choice. Our rich experience through valuable comments and users accumulate, so that each device structure is more reasonable, more mature technology. 1. efficient single screw extruder: screw speed of high-speed, high-yield high mixing screw design to ensure stable extrusion. 2. Mold: using the latest blue die or screw-type shunt composite die design, built-in temperature control device, resorted to more uniform, more convenient adjustment. 3. vacuum forming, spray cooling system: advanced water ring vacuum forming methods, roundness configuration flexibility to adjust the device operation, multiple spray tanks up to 6m, to ensure the quality of the pipe shape; box and contact parts are made of All stainless steel. The traction device: choose two claws, four claws, six claws, octopus traction device adapted to different specifications of pipe production needs. 5. Cutting device: we can be configured according to the requirements of sawing, sawing planet, chipless rotary knife and other means. 6. Control System: We have a variety of electrical control systems to choose from, such as PLC automatic control system, easy to operate, stable and reliable operation.
