Detailed number of hidden warm pipe materials should pay attention to quality
In recent years, floor heating has become a new type of heating method. Because of economic and environmental protection, many families will install floor heating. The key material for floor heating is floor heating pipe. Once the floor heating pipe is laid, it is not easy to change or repair, so the pipe is purchased. Very important. The following Xiao Bian has organized the top ten brands of floor heating pipes for everyone, and hopes to help everyone's purchase. The material of the floor heating pipe is divided into many types, specifically XPAPR cross-linked aluminum pipe, PE-X: cross-linked polyethylene 1, PAP: aluminum-plastic composite pipe 2, PP-B: impact-resistant polypropylene copolymer (Korea once said For PP-C), PP-R: random polypropylene copolymer, PB: polybutylene (super high temperature resistant pipe), PE-RT: high temperature polyethylene. The price of different materials will also be different. 1, PB tube PB material has excellent performance and has the reputation of "plastic gold". PB tube light weight, pressure resistance, impact resistance, low temperature resistance, high temperature performance, long-term use at 95 °C, the maximum use temperature of 110 °C, flexibility is the best of several commonly used warm tube, the use of heat Fused connections, reliable joints, but due to raw material prices higher. It is the most expensive of all the pipes. Price: generally 120 yuan / m. Imports are about 30 to 60 yuan more expensive. 2, imported PEX tube Including PEXa and PEXc, low temperature toughness, better than PPR more resistant to high temperature, good stress crack resistance, high temperature resistance up to 110 degrees, is the best of all plastic floor heating pipes, PEX floor heating pipe five poisonous and tasteless health, no corrosion Does not breed bacteria, the inner wall is smooth and does not obstruct the flow of water. PEX-A pipeline is a mature floor heating pipe, and the best technology and product quality; PEX pipe creep resistance, aging resistance, life expectancy of more than 50 years, the same building life; Thermal conductivity up to 0.45 / mk, is inside the plastic pipe The best thermal conductivity. Price: RMB 25/m for PE-Xa pipes, 20-30 yuan/m for imports, no additives for PE-Xc pipes, low raw material costs, and prices are generally around RMB 20/m. 3, cross-linked polyethylene plastic composite pipe (XPAP) The aluminum layer in the middle has an oxygen barrier function, which can also improve the internal and external pressure resistance of the pipe to a certain extent. It can maintain the shape after bending, but the bending radius is relatively large, and it may happen when it is installed or subjected to transient high temperatures. Delamination, and the price is higher. 4, PPR tube The price is low, high temperature performance is good, and welding is possible. However, the wall thickness is relatively large. It is difficult to bend in the construction of the floor heating, the rebound force is large, and the thermal conductivity is poor. Price: generally at 10 yuan / meter, but the price of accessories is much higher than the price of pipe. 5, PERT tube The advantages of the PPR tube have been retained, but no cross-linking has occurred, the tubes can still be connected by hot melt, the joints are reliable, the leakage is not easy to occur, the flexibility and low temperature resistance are also good, and the high temperature resistance is only 70 degrees, which is the PEX series of tubes In general, the blasting capacity is 40KG, PEX is 60KG, the flexibility of the pert pipe is not as good as the PEX, and carelessness in the transportation construction can easily result in the injury of the pipe, causing hidden troubles in the future warm use, corrosion resistance and creep resistance of the PERT pipe. The ability of thermal conductivity is normal and there is no good PEX pipe. The raw materials of PE-RT tubes can only be produced in South Korea, but the large quantities of raw materials needed on the market cannot be supplied by South Korea, so many counterfeit products are produced. The majority of counterfeit products produced by PE-X pipe manufacturers are foreign manufacturers. Price: 10 yuan / meter or so, is a more economical kind of pipe. PE-X pipe can not be hot melt connection, such as the damage in the construction of the entire pipeline to be replaced, it is not the performance of the hot melt connection, to maximize the quality of the project, a whole laying of geothermal pipe, plate There is no connection point in the process of the pipe, and the inlet and outlet pipes are respectively connected at the end to avoid the hidden trouble of leakage. The PE-RT pipe can be connected by hot melt. The wall of the geothermal pipe itself is only 2mm thick. The location of the hot melt is just a hidden danger of the project. Xiao Bian summary: It can be seen from the above comparison that the PEX series pipes (PEX-A, PEX-C) and PB pipes are better in the overall performance of the five commonly used floor heating pipes, especially the PEX-A pipes are more suitable for Various high-grade buildings,. In addition, considering the oxygen barrier performance of the floor heating pipe is also an important performance, it is also possible to select PEX-A or PB pipe and PEX-C pipe with oxygen barrier layer (such as EVOH).
