What are the differences between the two types of lean composite pipes?
As far as I know, at present, residential decoration water pipes are mainly divided into: galvanized pipe, UPVC pipe, aluminum plastic pipe, PPR pipe, copper pipe and stainless steel pipe.
Aluminum plastic pipe: aluminum plastic composite pipe is a more popular pipe in the market, because of its light weight, durability and convenient construction, its flexibility is more suitable for use in home improvement. The main drawback is that when used as a hot water pipe, due to long-term thermal expansion and cold contraction, it will cause the wall of the pipe to be dislocated so as to cause leakage.
UPVC: is a kind of plastic pipe, the interface in general by the glue, UPVC pipe freezing and heat resistance is not good, so it is very difficult for the hot water, because the pressure strength can not be applied to the pipe, so the cold water pipe is also rarely used. In most cases, the PVC pipe is suitable for wires, pipes and sewage pipes. In addition, in recent years within the technology sector that can make PVC more chemical additives butylphthalide soft, very high on the human body kidney, liver, testis, cause cancer, kidney damage, damage to the human body reconstruction system, the influence of the development of. So I suggest you don't buy it.
Galvanized pipe: most of the old house are used galvanized pipes, gas heating, now with the kind of pipe and galvanized pipe, galvanized pipe as a water pipe, use after a few years, produced a lot of rust in the tube, the outflow of water not only pollute the sanitary ware, and mixed with smooth inner wall corrosion caused by bacteria, heavy metal content in water too high, serious harm to human health. In 60s and 70s, developed countries began to develop new types of pipes, and galvanized pipes were banned. At present, the New District cold water pipe has rarely used galvanized pipe, and some of the hot water pipe is galvanized pipe.
