What are the commonly used water pipes? Which is better for domestic water pipes?

Water pipes are very important to our family, so it is very important to choose water pipes for family decoration. The quality of water pipes is closely related to the health of our diet. So it is a difficult problem to choose what kind of water pipe. There are many common water pipes in the market, such as aluminum-plastic pipes, galvanized pipes, UPVC pipes, PPR pipes, copper pipes and stainless steel pipes. Let's take a look at their characteristics. 1. aluminum-plastic pipe. Aluminum-plastic composite pipe is one of the commonly used domestic water pipes. The advantages of aluminum-plastic pipe are light weight, durability and convenient installation. In addition, the flexibility of aluminum-plastic pipe is also a common factor contributing to it. However, when aluminum-plastic pipes are used as hot water pipes, long-term thermal expansion and cold contraction are easy to cause dislocation of the pipe wall and eventually leak. 2. Galvanized pipe. Now, galvanized pipes are generally used for gas and heating. If galvanized pipes are used as water pipes, there will be a lot of rust in the pipes, which will make the metal content in the water too high and seriously endanger human health. 3.UPVC tube. Plastic pipes, actually. The frost resistance and heat resistance of this kind of pipe are not ideal, so it is difficult to be used as a hot water pipe. Moreover, because its strength can not meet the pressure requirements of water pipes. Therefore, UPVC pipes are mostly used as electric conduits and sewage pipes. 4.PPR tube. It is a new type of water pipe material. PPR pipes can be used as cold water pipes, hot water pipes and even pure drinking water pipes. Because of its non-toxicity, light weight, pressure resistance and corrosion resistance, it has now become a popular material. The interface of PPR pipe adopts hot melt technology, which will not age and leak even if it is used for a long time. In addition, PPR pipe claims to be a green advanced water supply material, which never scales, rusts or leaks. 5. copper tube. Strong corrosion resistance, sterilization is the advantage of copper tube. There are two ways to install copper pipes: clamping and welding. If welding is used, it will never leak like PPR water pipes. But copper pipes have a fatal disadvantage that they conduct heat quickly. 6. Stainless steel pipe. It is a kind of expensive water pipe, which is rarely used because of its difficult construction. The performance of stainless steel pipe is similar to that of copper pipe. In fact, PPR pipe is superior to other pipes in connection mode and actual service life, so it is suggested that PPR pipe is the best choice for domestic water pipes. At present, the PPR water pipe of Poly Pipeline is guaranteed in performance and safety. The above is the introduction of common water pipes and pipes on the market. You can refer to which one is suitable for your home. And PP-R pipe is regarded as a green and reliable pipe by building water supply and drainage circles. The fittings of PP-R pipes are also made of PP-R material, which will be used more in general home decoration. Brand, Liansu, Wei Xing, Jinde, Rifeng have a good reputation. You can compare several brands. I hope my answer can help you!
