1. Galvanized iron pipe Galvanized iron pipe is the most used material at present. Due to corrosion of galvanized steel pipe, the content of heavy metal in the water is too high, which affects human health. Many government departments in developed countries and regions have begun to explicitly prohibit the use of galvanized iron pipes. At present, China is gradually phasing out this type of pipeline.
2. Brass Pipe A more traditional but expensive pipe material that is durable and easy to construct. In many imported sanitary products, brass is the first choice. Price is the most important factor affecting its use. In addition, copper corrosion is also a factor on the one hand.
3, stainless steel pipe stainless steel pipe is a more durable pipe material. However, its price is relatively high, and the construction process requirements are relatively high. Even though its material strength is hard, on-site processing is very difficult. Therefore, the probability of being selected in the renovation project is low.
4, aluminum-plastic composite pipe aluminum-plastic composite pipe is currently a more popular on the market, a pipe, because of its light, durable and easy construction, its flexibility is more suitable for home use. Its main drawback is that when it is used as a hot water pipe, due to the long-term thermal expansion and contraction, the pipe wall may be misaligned and cause leakage.
5, stainless steel composite pipe stainless steel composite pipe and aluminum plastic composite pipe in the structure of similar, to a certain extent, the performance is relatively similar. Also, the construction process is still a problem due to the strength of the steel.
6, PVC pipe
PVC (polyvinyl chloride) plastic pipe is a modern synthetic material pipe. However, in recent years, the scientific and technological community has discovered that chemical additives that can make PVC more flexible will have a great impact on the kidneys, liver, and testicles in the human body. This will lead to cancer and kidney damage and damage the human body's functional reengineering system and affect development. In general, because its strength can not be applied to the pressure requirements of water pipes, it is rarely used in water pipes. In most cases, PVC pipes are suitable for wire and sewage pipes.
7, PP tube
PP (Poly Propylene) tubes are divided into various types, which are:
1, PP-B (block copolymer polypropylene) due to the use of welding technology in construction, it is also commonly known as hot-melt tube. Due to its non-toxicity, light weight, pressure resistance, and corrosion resistance, it is becoming a popular material, but at present, there are few choices for decoration projects. Generally speaking, this material is not only suitable for cold water pipes, but also suitable for use. In hot water pipes, even pure drinking water pipes.
2, PP-C (modified polypropylene copolymer) pipe, performance is basically the same as above.
2, PP-R (polypropylene random copolymer) pipe, performance basically the same as above.
The physical properties of PP-C (B) and PP-R are basically similar, the application scope is basically the same, and they can be used interchangeably in engineering. The main difference is that PP-C (B) material is superior to PP-R in resistance to low temperature brittleness; PP-R material is better in heat resistance than PP-C (B). In practical applications, when the liquid medium temperature is ≤5°C, the PP-C(B) tube is preferred; when the liquid medium temperature is ≥65°C, the PP-R tube is preferred; when the liquid medium temperature is 5°C-65°C In the area, PP-C (B) and PP-R are basically the same. Second, the pipe installation precautions In the decoration, waterproofing is often more important than any topic. What needs to be taken care of during the installation and use of the pipeline?
1. The installation pipeline must find a professional mechanic. No matter how luxurious and upscale your decoration, if you are not willing to spend money in this area, it is not worthwhile. Frequent bursts or leaks in the pipeline will cause the pipe itself to cost tens, hundreds, or even thousands of times more.
2. The boost test must be performed after installation. Pressurization tests are generally performed at 1.5 times the water pressure, and there should be no leakage during the test.
3. Test methods under no pressure:
1) Close the water main valve. (ie the water switch in front of the water meter)
2) Open the faucet inside the room for 20 minutes to ensure that no water is dripped and then close all taps.
3) Turn off the water inlet switch of the water storage device such as the toilet tank and washing machine.
3) Open the main valve of the water pipe.
4) Check whether the water meter is moving 20 minutes after opening the main valve, including slow walking.
If there is movement, it is leaking. If you don't move, it's okay.
4, In daily use, if you find the following conditions, check the relevant pipeline as soon as possible:
1) Mild foam on the surface of the wall paint.
2) Baseboard or wood floor is black and fine bubbles appear on the surface
