How to choose a safe and reliable "water supply pipe"?

The water supply pipe is responsible for the transmission of water in our daily life, so the material of the water pipe directly affects the quality of water and our health. There are countless types of water supply pipes on the market. How to design and select materials for the designer of the construction unit is a very important task, which is related to people's livelihood and project cost. This requires us to understand several pipelines on the market. Let’s take a look at the mainstream water supply pipes:

Galvanized iron pipe

The most popular product in China is a product that is eliminated in foreign countries. There is only one reason. The galvanized iron pipe will corrode, affect the water quality, cause the heavy metals in the water to exceed the standard, and cause serious health problems to people. Although it is cheap, health cannot be guaranteed.

PVC pipe

PVC (polyvinyl chloride) plastic pipe is a modern synthetic material pipe. However, in recent years, the scientific and technological circles have discovered that the chemical additive phthalein, which can make PVC softer, has a great impact on the kidneys, liver and testes in the human body, causing cancer, kidney damage, damage to the human body's functional reconstruction system, and affecting development. In addition, in the process of reproduction, the appearance of the pipeline is required to be beautiful, and the speed of the pipe is stable. Stabilizers are often required. The stabilizer contains a large amount of heavy metals, which is a major hazard. Heavy metals can pollute the soil and water. Generally speaking, due to its The strength is far from suitable for the pressure-bearing requirements of water pipes, so it is rarely used in water pipes. In most cases, PVC pipes are suitable for electrical conduits and sewage pipes.

PPR tube

PP-R water supply pipe is currently the most popular product. At present, the most popular in the world is the American polygon pipe, which is called Poly Pipeline in China. Its water supply pipe series include: PPR antibacterial pipe, PPR stable aluminum coating, PPR copper pipe , PPR quality pipes, etc. are all first-line products in the market, safe, stable, moderately priced, relatively cost-effective, and have a 50-year warranty.

copper tube

The cost is quite expensive, which is beyond the reach of ordinary groups. Only the local tyrants have the strength to enjoy it. Many foreign high-end bathrooms also often appear copper pipes. Although they are good, they are expensive. At present, the PPR copper pipe produced by Poly Pipeline combines the advantages of copper pipe and PP-R pipe. The thermal conductivity is lower than that of copper pipes, and it has excellent thermal insulation performance, which is suitable for high-end residences.

stainless steel pipe

A very good product, but unfortunately the material is too hard and the price is too high, which leads to inconvenient processing, easy damage and high waste probability. Therefore, stainless steel pipes are rarely seen in the process of using and processing.

Aluminum-plastic composite pipe

The aluminum-plastic composite pipe is a relatively 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. Its main disadvantage is that when it is used as a hot water pipe, the pipe wall will be dislocated due to long-term thermal expansion and contraction, resulting in leakage.

Stainless steel composite pipe

The stainless steel composite pipe is similar in structure to the aluminum-plastic composite pipe, and to a certain extent, the performance is also relatively similar. Again, the construction process remains an issue due to the strength of the steel.
