The real PPR pipe should meet the standard GB / T18742-2002 << hot and cold water plastic pipe system - PP part of the pipe >> pipe fittings should meet the standard GB / T18742-2002 << hot and cold water plastic pipe system - PP Part III Fittings >>; Pseudo PPR pipes and fittings are not capable of passing the above criteria. It should be noted that the life of pseudo-PPR pipe is only 1 to 5 years, while the real PPR tube life are more than 50 years.
PPR pipe how to identify, PPR pipeline is widely used in industrial and residential building life, health drinking water and hot water heating. PPR pipe points hot and cold water pipes 2: cold water pipe wall thin, hot water pipe wall thickness. So the resistance to fracture in the hot water pipe performance is much better, the price of hot water pipe is also more expensive than the cold water pipe. Many manufacturers for the sake of insurance, the construction process, regardless of hot and cold water pipe cracking, improve the safety factor.
1, good soft PPR pipe, pipe is not susceptible to extrusion and deformation, even if the deformation does not break, and greatly reduce the use of joints.
2, corrosion resistance, waterproof scaling, PPR pipe, pipe chemical properties can resist the chemical erosion of water, while smooth the inner surface can avoid the formation of scale.
3, high temperature, high pressure PPR pipe, pipe at room temperature to withstand water pressure of 45 kg / square centimeter, the pipe deformation temperature is 112 degrees Celsius.
4, long life PPR pipe, pipe anti-aging strong, the normal role of the mission to more than 50 years.
5, the construction of simple and rapid PPR pipe, pipe fittings make the construction of a very fast, and easy to connect (with hot melt machine socket connection), safe and reliable.
6, the real PPR tube affordable As the construction is simple, there is no contradiction between the other projects and the impact of shorten the construction period, the construction cost savings of 20% than copper, with superior economy.
Therefore, consumers should be careful when buying, we must choose the right, large manufacturers of production, quality assurance of the pipe, the other in the installation, but also some attention, may wish to listen to expert advice.
