Advantages of PPR PIPE
PPR pipe is a new type of energy-saving pipeline product, which mainly has the following characteristics:
(1) Lightweight: density is 0.91g/cm3, ppr tube is only one-ninth of steel pipe, and one-tenth of copper pipe. Due to its lightweight, it can greatly reduce the transportation cost and the construction intensity of installation.
(2) Hygienic and non-toxic green building materials: PPR pipes are polyolefin thermoplastics, whose molecules are only composed of carbon and hydrogen, without harmful and toxic elements, and have reliable hygienic performance. The whole process of raw material synthesis, molding processing, product use, and disposal will not cause adverse effects on the human body and the environment and is called green building materials. PPR pipes can be used not only in cold and hot water systems but also indirect drinking water systems.
(3) Heat-resistance and heat preservation are energy-saving products: PPR pipe Vicat heat-resistant temperature is 131.3℃. Under certain working pressure and 70℃ working temperature, it can be used for a long time (more than 50 years), and the maximum working temperature is 95℃. Fully meet the requirements of the hot water system specified in the building water supply and drainage design code.
(4) Good heat preservation performance: The thermal conductivity of the PPR pipe is 0.23w/m℃, which is only one-twentieth of that of steel pipe (43-52w/m℃). It has better heat preservation performance. Compared with metal pipes, Used in hot water and heating systems, it can save a lot of insulation materials and energy.
(5) Hot-melt connection, safe and reliable: PPR pipe has good heat-welding performance. The hot-melt connection between pipes and fittings made of the same PPR material is the fusion of molecules and molecules, and there is no obvious interface. The entire pipeline system The connection becomes a whole, so the hot-melt connection of this method is more reliable than other pipes’ solvent bonding, mechanical connection, an elastic sealing socket connection, and the operation is simple, the speed is fast, and it is especially suitable for direct buried and hidden applications. During construction, there is no need to consider whether there will be leakage at the connection part during long-term use.
(6) Good corrosion resistance: Except for a few oxidants, it can withstand the erosion of a variety of chemical media, will not rust, will not corrode, will not breed bacteria, and will not have electrochemical corrosion.
(7) Water flow resistance is small: the inner wall of the ppr pipe is smooth, will not scale, and the wear resistance system is only 0.007, which is much lower than that of the metal pipe, and the water flow capacity is 30% higher than that of the metal pipe of the same specification
(8) The ppr tube has no pollution to the environment during production, construction, and use, and will not cause white pollution problems, and is a green product.
