Aluminum lined composite pipe is new composite pipe Ltd. Jiang 苏润硕 new R & D pipeline. On the water pipe applications has light weight, 100% oxygen barrier, UV irradiation, clean, easy installation, sealing strong, maintenance, etc., addressed in the indoor surface mounted plastic pipe bending after thermal expansion and contraction, fear of impact, easy to aging and other defects. Connection melt socket connection, safe and reliable, saving time and effort. Scope is mainly used in the construction of hot and cold water supply, including industrial, residential hot and cold water and heating system fields. Advantages a) excellent mechanical properties: aluminum-lined composite pipe is lightweight rigid tube, not because of accidental impact or crushing by beating caused the loss and damage during installation and use. b) thermal conductivity: aluminum-lined composite pipe inner layer of polypropylene thermal conductivity of 0.24w / mk, and between 20 ℃ and 60 ℃ constant. With its production of pipe has excellent insulation properties. c) Economy: melt flow rate polypropylene inner layer of aluminum-lined composite pipe minimal changes, a melt index of the rate of change of the same product type polypropylene generally <6%. Even after several heated plastics, can maintain the original excellent performance, greatly improving the reuse of raw materials and reduce the cost of pipe production. d) long-term anti-static properties: anti-static direct impact on the life long aqueduct. Aluminum lined composite pipe by hydraulic test hydraulic pipeline corrosion better than competitive, polypropylene pipes, pipe fittings combined with good long-term anti-static properties and long life. e) excellent weldability: melt connection in the pipeline will not melt well and shrinkage cracks resulting in leakage, enabling the maintenance of the pipeline system, is typical properties of polypropylene tubing. Product Standards and Specifications Product performance standards: CJ / T 321-2010 Yun-seok brand aluminum lined (lining PP-R, PE-RT, PE, PB) composite pipe perfect performance: 1, environmental health, toxic suppression bacteria food-safety grade wading raw materials, anti-chemical pollution, noise mute transport process;? insulation, heat loss along the metal pipes 1/200 only, transmission fluid, easy to scale, friction coefficient of only 0.007 . 2, firm structure, safe and reliable lightweight rigid pipe, smooth vertical and horizontal, not damaged, the entire melt socket connection, to prevent leakage problems, a unique tube design prevents spills exposed; super low temperature, corrosion resistance oxygen, no galvanic corrosion and other properties, the system can be maintenance-free operation for more than 50 years, the maximum withstand up PN2.5Mpa nominal pressure. 3, powerful, suitable for a wide range of hot and cold water construction water supply pipeline system; building indoor heating, central air-conditioning duct system; various types of food sanitation, drinking water, medicine preparations piping systems; various types of chemical agents, the hospital drug distribution pipeline system.
