The water pipes used in the old houses are all galvanized. After a few years of use, the galvanized pipes will have a lot of rust in the pipes. The water that flows out will not only pollute the sanitary ware, but will also be mingled with bacteria that grow on the inner wall. This rust causes corrosion. The excessive content of heavy metals in water seriously harms human health. The following small series introduces waterway construction pipe classification .
Waterway construction pipe classification
1, UPVC pipe
This type of UPVC pipe is not very resistant to freezing and heat, so it is generally not used as a hot water pipe. This type of water pipe is suitable for wire and sewage pipes in most cases. In addition, there are scientific findings that UPVC pipe softening chemical additives can have a great impact on the kidneys and liver of human body, which can damage the human body's functional reengineering system and affect development.
2, aluminum plastic pipe
This type of aluminum plastic pipe is one of the more popular pipes on the market. The pipe is light, durable, and convenient to construct, but its disadvantage is that when it is used as a hot water pipe, it will cause misalignment of the pipe wall due to long-term thermal expansion and contraction. Causes leakage.
3, PPR tube
PPR pipe has many advantages. It can be used not only as a cold water pipe but also as a hot water pipe. The pipe is non-toxic, light weight and corrosion-resistant. In addition, the interface of the PPR pipe adopts the hot-melt technology. The pipes are completely fused together. Therefore, once the pressure test is passed through the installation, there will be no time-consuming aging leakage phenomenon like the aluminum-plastic pipe, and the PPR pipe will not be fouled. .
4, copper tube
The copper pipe has the advantages of corrosion resistance, sterilization, and the like, and there are two types of interface: card sleeve and welding. Welding is welded to the interface at the same time through oxygen, so that it can be leak-proof like a PPR pipe. However, the disadvantage of copper pipes is that they are expensive, and very few residential water supply systems use copper pipes.
5, stainless steel tube
The construction of stainless steel pipes is more difficult, and it is generally less used. The performance is similar to that of copper pipes.
Editor's summary: The introduction of water pipeline construction classification is introduced here. I hope to be helpful to everyone. I would like to know more relevant information and pay attention to this site information.
