First, the production process of PPR tube Automatic feeding - heating extrusion - vacuum sizing —— - secondary immersion æ³ - product printing - traction - cut to length - inspection - packaging - storage Second, the characteristics of the PPR tube: 1. Hygienic and non-toxic: This product is a green building material and can be used in pure water and drinking water pipeline systems. 2, corrosion resistance, non-fouling: can avoid the rust caused by the corrosion of the pipe basin, yellow spots on the bathtub, can avoid the corrosion caused by pipe fouling The blockage. 3, high temperature and high pressure: the pipeline water temperature can reach up to 95 °C. 4. Insulation and energy saving: The thermal conductivity is only one-twoth of that of metal pipes, which is excellent for energy saving of hot water pipes. 5, light weight: the specific gravity is only one-seventh of the metal tube. 6. Beautiful appearance: The inner and outer walls of the product are smooth, the fluid resistance is small, the color is soft, and the shape is beautiful. 7, easy to install *: using hot melt connection, completed in a few seconds, security can be *. 8. Long service life: Under the specified long-term continuous working pressure, the service life can reach more than 50 years. Third, the application range of PPR tube: 1. Residential hot and cold water piping system; 2. Transportation and discharge of industrial water and chemical substances; 3. Pure water and drinking water pipelines; 4. Beverage and drug production and delivery systems; 5. Pipe for compressed air; 6. Other industrial and agricultural pipes. Fourth, PPR tube strengths and safety hazards Poly Propylene Random, a random copolymer polypropylene tube, is a new type of water pipe used in today's thriving countries. The PP-R pipeline has been used in Europe for more than 10 years. Because of its excellent functions, in recent years, its market has been preemptively ahead of other plastic water pipes. The current national connotation of building cold water and heating is simply adopted. PVC-C, PE-X, aluminum-plastic pipe and PP-R pipe, and gradually transition to PP-R pipe. The PP-R tube is one of the hot spots for this production and use. The characteristics of PP-R pipe are gradually recognized by China's pipeline engineering community. PP-R pipe has clean and non-toxic except common plastic pipe with light weight, corrosion resistance, high strength, no scaling, long service life and so on. Good low temperature impact resistance, long-term heat resistance and pressure resistance, superior leveling and energy saving functions, it is a true green building material product, and it also has system connection and convenient installation, pipe fitting and strong, and is eternal. Features such as convergence. In addition, PP-R pipe has excellent function price ratio. At present, there are more than 300 PP-R pipe production plants in China. The existing building materials market PP-R pipe is various, because of various reasons, the quality of PP-R pipe is still Compared with the convexity, the strength and characteristics of the PP-R pipe can not be fully expressed, which affects the function of the pipeline engineering, and also lays a safety hazard to the quality of the responding project.
