The first step in doing a good job in hydropower projects is to choose a good quality hydropower pipe. However, once you get to the building materials city, you will find that the pipes used for decoration are dazzling. I really don't know what to choose. There are PPR pipes, copper pipes, aluminum plastic pipes, PVC pipes, stainless steel pipes, etc., which have various materials and different materials. The prices are also uneven, and the price difference between the lowest price and the most expensive price is nearly 10 times. In addition to the differences in professional performances such as pipe diameter, wall thickness, and pressure level, there are also many fake and shoddy products that use the name of “å‚å牌â€.

PPR pipe dominates
“As a pipe for hydropower projects, it has been updated several times in just two or three years.†According to Zhao Taiyu, registered house inspector of Woodpecker Decoration Supervision Company, the earliest were stainless steel pipes, galvanized steel pipes, then aluminum plastic pipes, and then included PPR. Plastic tubing, among others, is the thin-walled copper tube currently connected with the world.
Among them, galvanized pipes and PVC pipes have almost been eliminated. Aluminum composite pipes, copper pipes and stainless steel pipes have their own actual usage in home decoration due to their own defects or high prices. Now the PPR pipe is the most commonly used one.
However, "these pipes have not passed the test of time. In recent years, the overall piping system problems in some buildings have caused many hidden troubles in previous years." For example, turbid yellow water flows out of galvanized pipes, and aluminum-plastic pipes are under pressure. Explosive when cracked. Even if it is a mainstream PPR pipe, there are some problems: in the long-term use, there will be precipitates, and the harm to the human body has not yet been conclusive.

Copper tubes are the most widely used
What kind of pipe is the best quality? It is understood that the copper pipe is the most widely used internationally. Copper pipes have obvious advantages in terms of high and low temperature resistance, strength, environmental protection and hygiene. Copper pipes occupy a monopoly in water supply and drainage systems in developed countries or regions. For example, in Hong Kong, copper pipes account for about 70% of the market, and domestic water systems in residential buildings are required to use copper pipes. Older developed countries such as the United Kingdom have higher copper penetration.
However, in China, the use of copper pipes has been low. Wuhan Lucky Group Wu Jianji, model homeroom and craft lecturer, told reporters that “in addition to the costly factors, it also has a lot to do with the concept of use by everyone.†In the domestic urban market, according to optimistic estimates, there is approximately 10% usage rate. At present, copper pipes are mainly concentrated in high-end users, such as five-star hotels and high-end residential communities. “In contrast, the bursting of water pipes in these places will be significantly less.â€

How to buy PPR tube
Just purchased a new home, many people are busy decorating their love nest. How to choose the right pipe at the right price is an important thing for them. The following tips will teach you how to identify the PPR tube.
1. "Touch": whether the texture is delicate and whether the particles are even. At present, PPR pipes on the market are mainly in several colors of white, grey and green. Under normal circumstances, recycled plastics cannot be made white, so many people think that white is the best. In fact, this view is more one-sided. As technology has improved, color is not a criterion for discriminating PPR tubes. The quality of the pipe does not solve the problem. If it is touched, it is likely that the coarse particles are mixed with other impurities.
2. "Smell": There is no smell. The main material of the PPR tube is polypropylene. Good tubes have no odor, and bad ones have a strange smell. It is very likely that polyethylene is blended instead of polypropylene.
3. "Kneading": PPR pipe has a considerable hardness, and it can be shaped into a deformable pipe, which is certainly not a PPR pipe.
4. "ç ¸": Good PPR pipe, "Resilience" is good, too easy to shatter natural PPR pipe is not good. However, the hardness is not equal to the flexibility, and we have no doubt about the PPR tube that cannot be broken. Because some unscrupulous manufacturers increase the hardness of pipes by adding too many impurities such as calcium carbonate, such pipes are prone to embrittlement for a long time.
5. "Burn": Igniting a fire, very intuitive and very useful. PPR pipes that contain recycled plastics and other impurities in their raw materials will emit black smoke and have a pungent odor; good materials will not only emit black smoke and odor after burning, but the burnt-out liquid will remain clean after burning.
