PPR pipe, copper pipe, aluminum-plastic pipe, galvanized pipe, PVC pipe, thin-walled stainless steel pipe, PVC-lined stainless steel pipe. 1. PPR pipe: As a new type of water pipe material, PPR pipe has unique advantages, hygienic and non-toxic, and can be used as both a cold water pipe and a hot water pipe. Advantages: moderate price, stable performance, heat and heat preservation, corrosion resistance, smooth inner wall without scaling, safe and reliable pipeline system, impermeable, service life of up to 50 years. Disadvantages: However, special tools are required for connection, and the connection surface needs to be heated. If the heating time is too long or the socket is inserted too much, the water flow will be blocked. 2. Copper pipe: It is the first-class product in the water pipe. The order of copper in the chemical activity is very low, and it is lower than hydrogen, so it has stable performance and is not easy to corrode. According to relevant information, copper can inhibit the growth of bacteria and keep drinking water clean and hygienic. Advantages: high strength, stable performance, sterilization, and not easy to corrode. Disadvantages: high price and difficult construction. In cold winter, it is easy to cause heat loss, large energy consumption and high use cost. 3. Aluminum-plastic pipe: Aluminum-plastic pipe was once a popular pipe material on the market. Because of its light weight, durability and convenient construction, its bendability is more suitable for use in home decoration. In Guangdong and Shanghai, where the decoration concept is relatively new, the aluminum-plastic pipe has gradually lost its market and belongs to the eliminated product. Advantages: The price is relatively cheap, it can be bent arbitrarily, the surface is smooth, and the construction is convenient. Disadvantages: easy aging, many hidden dangers in use, short service life, practice has proved that the leakage phenomenon is very easy to occur at the pipe connection. 4. Galvanized pipe: When you open a water pipe that has not been used for a long time, you suddenly find "yellow" water flowing out. This kind of thing is very easy to happen in galvanized iron pipes in old houses. Such "yellow" water is also harmful to the human body. . Galvanized pipes have been banned since 2000. At present, galvanized pipes are rarely used in cold water pipes in newly built communities. Advantages: complete varieties, many pipe fittings. Disadvantages: It is an outdated product prohibited by the state, which is easy to corrode and rust, resulting in poor water flow and easy to cause water pollution. 5. PVC pipe: In fact, it is a kind of plastic pipe, and the interface is generally bonded with glue. Because its frost resistance and heat resistance are not good, it is difficult to be used as a hot water pipe; the strength is not suitable for the pressure requirements of water pipes, so cold water pipes are rarely used. In most cases, PVC pipes are suitable for electrical conduits and sewage pipes. In addition, the chemical additive phthalein, which makes PVC softer, has a great impact on the kidneys, liver and testes in the human body, and can cause cancer and kidney damage, so it is not recommended for everyone to buy it. Advantages: light, easy to install, low cost, and not easy to corrode. Disadvantages: Poor quality will be very brittle, easy to break, and easy to deform when heated. 6. Thin-walled stainless steel pipe: Thin-walled stainless steel pipe is corrosion-resistant and not easy to rust, safe and reliable to use, has strong impact resistance, and relatively low thermal conductivity. However, the price of stainless steel pipes is relatively high, and in addition, stainless steel models that are resistant to chloride ions in chlorine water in water should be used. Thin-walled stainless steel pipes are connected by welding, threading, sealing and other methods. Advantages: not easy to oxidize and rust, strong impact, low heat conduction. Disadvantages: high cost, stainless steel models that are resistant to chloride ions in water should be used. 7. PVC-lined galvanized steel pipe: PVC-lined galvanized steel pipe has the advantages of high strength and rigidity of metal pipe and corrosion resistance of plastic pipe, and also overcomes the shortcomings of the two types of materials. Advantages: There are many pipe fittings and complete specifications. Disadvantages: The actual diameter of the pipe used in the pipeline becomes smaller; when the ambient temperature and the temperature of the medium change greatly, it is easy to separate the layer and cause the quality of the pipe to decrease.
