Today we are talking about how to classify pipes in waterway construction. What is the use?
Galvanized pipe:
Most of the old iron and steel houses in Hunan Province are galvanized. The type of iron used for gas and heating is also a galvanized pipe. The galvanized pipe is used as a water pipe. After a few years of use, a large amount of rust is generated inside the pipe. Yellow water flows out of the pipe. It not only pollutes the sanitary ware, but also contains bacteria that grow on surfaces that are not smooth. Corrosion causes excessive levels of heavy metals in the water, which seriously endangers human health. In the 1960s and 1970s, developed countries in the world began to develop new types of pipes and banned galvanized pipes one after another. China's Ministry of Construction and other four ministries also issued a document stating that galvanized pipes have been banned since 2000. At present, galvanized pipes have rarely been used for cold water pipes in new communities, and hot water pipes in some communities use galvanized pipes.
Upvc tube:
In fact, it is a kind of plastic pipe, and the interface is generally glued. Hunan Steel's Upvc pipe is not good in anti-freezing and heat resistance, so it is difficult to be used as a hot water pipe because its strength cannot be applied to the pressure of the pipe. Requirements, so cold water pipes are rarely used. In most cases, PVC pipes are suitable for wire and sewage pipes. In addition, in recent years, the scientific and technological community has discovered that chemical additives that can make pvc softer have a great impact on the kidneys, liver, and testicles in the human body. This can lead to cancer and kidney damage, and damage the human body's functional reengineering system and affect development. Therefore, it is recommended that you do not buy it.
Aluminum plastic pipe:
Aluminium-plastic composite pipes are one of the more popular pipes on the market. The current market is better known as Rifeng and Kinder. Due to its light weight, durability, and ease of construction, its flexibility is more suitable for use in home furnishings. Its main drawback is that when it is used as a hot water pipe, due to long-term thermal expansion and contraction, the wall of the pipe may be misaligned to cause leakage. Many residential districts in Beijing use aluminum-plastic pipes. In the relatively new concept of decoration in Guangdong and Shanghai, aluminum-plastic pipes have gradually disappeared from the market. Currently, aluminum-plastic pipes are still active in the Beijing market. It is believed that in the near future, the aluminum market in Beijing Plastic pipe will also face elimination.
Ppr tube:
As a new type of Hunan steel pipe material, PPR pipe has unique advantages. It can be used as a cold water pipe or a hot water pipe. Because it is non-toxic, light weight, pressure resistance, corrosion resistance, it is becoming a The promotion of the material, the current selection of decoration projects in Beijing is still relatively small, PPR pipe not only applies to cold water pipes, but also applies to hot water pipes, and even pure drinking water pipes. The interface of the PPR pipe adopts hot-melt technology. The pipes are completely integrated into one another. Therefore, once the pressure test is passed through the installation, aging leakage will not occur for a long time like the aluminum-plastic pipe, and the PPR pipe will not be fouled. At present, Beijing Some high-end residences and apartments generally use PPR water pipes as cold water pipes and hot water pipes. PPR pipes are said to never foul, never rust, never leak, and green advanced water supply materials.
Copper tube:
Brass tube has the advantages of corrosion resistance, bacteria elimination, etc. It is the superior product in the water pipe. There are two types of copper pipe joints: card sleeve and welding. The card sleeve is the same as the aluminum plastic pipe, and there is a problem of aging leak for a long time, so In Shanghai and other places, most of the users who install copper pipes are welded. The welding is through the welding of oxygen at the interface. This can be the same as the PPR pipe. It never leaks. One of the disadvantages of the copper pipe is its fast heat conduction, so it is famous. The hot water pipes produced by Shanghai Sanjing, Baoyang and other copper pipe manufacturers are covered with plastics and foaming agents that prevent the heat from being emitted. Another disadvantage of copper pipes is that they are expensive, and there are very few residential water supply systems that are copper pipes. I'm afraid it will only be seen in export apartments and high-end villas. If you plan to change the water pipe and think that the copper pipe is good, it is recommended that you use a soldered connection. The users of the Hunan Iron and Steel Group mentioned that the British IBP copper pipes are located in the Xisanqi Store of the Orient House. I have not used them and everyone can go and inspect them.
Stainless steel pipe: It is a very expensive water pipe. Construction is difficult and it is rarely used. The performance is similar to that of copper pipe.
Plug: Bulkhead, used to close the outlet after the water pipe is installed. Take off when installing the tap!
Mixing valve: A mixing valve is a valve that mixes hot and cold water. In fact, the valve itself can not be mixed, just pick up the cold, hot water pipe, played a mixed role.
Galvanized pipe:
