1, PP-R tube
This is a new type of water pipe material, which can be used as both cold water pipe material and hot water pipe material. Non-toxic, light, corrosion-resistant, not easy to age, not scaling; However, the high temperature resistance and pressure resistance are not very good, and the length of each section is limited, so it is impossible to zigzag construction.
2. Aluminum-plastic pipe
Aluminum-plastic pipe is a new type of extruded composite pipe. This is a popular pipe in the market at present. It is light in weight, durable and easy to construct, and the aluminum-plastic pipe can be used in home decoration. The inner and outer layers of aluminum-plastic pipes are made of special polyethylene materials, which are clean and non-toxic. Excellent high and low temperature resistance and long service life. However, when it is used as a hot water pipe, the long-term cold and hot changes will make the pipe wall dislocation, which will lead to water leakage.
3. Copper tube
Copper tube has the advantages of corrosion resistance and sterilization, and is the top grade of water pipe material. The price is expensive, and it is easy to leak when using the card sleeve.
4. Lead pipe
PB pipe is recognized as a non-toxic, odorless and durable pipeline material, which can be recycled, with low energy consumption, high surface finish and good flexibility in the whole life cycle. PB pipe is soft, easy to crack due to high temperature collision, and has high construction requirements, so protective measures must be taken.
5. PVC
With the development of science and technology, household water pipes made of PVC have appeared, and PVC is a polymer material. At present, most water pipes on the market are made of this material. Because of its low cost, it is widely used. However, the material of this water pipe is white or light yellow, but this does not affect the use of water.
