What are the materials of the water pipe?

Currently on the market according to the material points there are mainly the following kinds of water pipes:

1, copper: a more traditional but more expensive pipe material, durable and construction is more convenient, but easy to produce copper green, precipitation of hazardous substances, construction is cumbersome, expensive, and poor insulation performance.

2, galvanized iron pipe: galvanized iron pipe is currently the largest use of a material, due to the corrosion of galvanized iron pipe caused by high levels of heavy metals in the water, affecting human health, many developed countries and regional government departments have begun to expressly prohibit the use of galvanized iron pipe.

3, PVC pipe: PVC (polyvinyl chloride) plastic pipe is a modern synthetic material pipe. However, in recent years, the scientific and technological community found that the chemical additives that can make PVC become more soft phthalide, on the human body kidney, liver, testicles have a great impact on the human body, can lead to cancer, kidney damage, damage to the human body's function of the recycling system, affecting the development.

4, PP pipe: PP (Poly Propylene) pipe is divided into a variety of, respectively: PP-B (block **** polypropylene) due to the construction of solvent technology, so also commonly known as thermosoluble pipe; PP-C (modified **** polypropylene) pipe; PP-R (random **** polypropylene) pipe. Inexpensive, corrosion-resistant, easy to install; but in high-pressure, high-temperature, exposed environment is easy to fracture, aging, life expectancy of only 1/3 of the life expectancy, coupled with plastic adhesion prone to bacterial growth, easy to fold out of hazardous substances, a serious impact on drinking water hygiene and human health.

5, aluminum-plastic composite tube: because of its light weight, durability and ease of construction, and its bendability is more suitable for use in home furnishings. Its main disadvantage is that when used as a hot water pipe, due to long-term thermal expansion and contraction will cause the wall of the pipe misalignment resulting in leakage.

6, stainless steel composite tube: stainless steel composite tube and aluminum composite tube in the structure is similar, to a certain extent, the performance is also relatively similar. Similarly, as a result of composite materials, when used as a hot water pipe, due to long-term thermal expansion and contraction will cause wall dislocation resulting in leakage, and composite materials are not really healthy materials.

7, stainless steel pipe: stainless steel water pipe service life of up to 100 years, high strength, non-corrosive, no excessive exudate, up to 0 pollution, is the most hygienic water pipe; low heat conduction coefficient, heat preservation is good, is 4 times the iron pipe, copper pipe 25 times, especially for hot water; stainless steel water pipe in addition to the advantages of metal piping, high pressure, high temperature, etc., and the surface of the strong oxide film Stainless steel has excellent corrosion resistance, the inner wall is clean and does not breed bacteria, does not fold out harmful substances, can keep the water pure and sanitary, to eliminate secondary pollution. Pressure stainless steel water pipe connection fast, safe, beautiful, maintenance-free after installation, test life of up to 100 years, maintenance-free 70 years.

At present, PPR is cheaper and more commonly used, the more famous brands are Weixing, Rifeng, Sinoma, Jinde, etc.; Stainless steel water pipe is now more and more people pay attention to due to health, environmental protection, hygiene, more than the price of the well-known brands such as Foliant, Meiya, Zhengkang.
