There are several kinds of domestic water pipes
For a long time no water pipe, suddenly opened, but found that the outflow is "yellow" water, the old house galvanized pipe in the very easy to happen such a thing, such a "yellow" water on the human body is also harmful. Galvanized pipes have been banned since 2000, and galvanized pipes are seldom used in the new district.Advantages: a wide range of products, fittings and more matching.Disadvantages: belong to the National prohibition of the use of obsolete products, corrosion, rust, resulting in poor flow, water pollution is easy to cause
In fact, it is a plastic pipe, and the interface is usually glued with glue. Because of its poor frost resistance and heat resistance, it is difficult to use as a hot water pipe. The strength is not applicable to the pressure requirements of water pipes, so cold water pipes are seldom used. In most cases, the PVC pipe is suitable for wires, pipes and sewage pipes. In addition, make PVC become softer chemical additives, phthalocyanine, the body of the kidneys, liver and testis have great influence, can lead to cancer, kidney damage, so do not suggest that you buy.The utility model has the advantages of portability, simple installation, low cost and easy corrosion.Disadvantages: poor quality will be brittle, easy to break, and also easy to deformation when heated.
Aluminum plastic pipe used to be a popular pipe in the market. Due to its light weight, durability and convenient construction, it is more suitable for use in home decoration. In the renovation concept of the new Guangdong and Shanghai, aluminum pipe has gradually no market, belongs to be eliminated products.Advantages: the price is cheaper, it can bend freely, the surface is smooth and convenient for construction.Disadvantages: easy aging, many hidden dangers and short service life. It is proved by practice that leakage is easy to occur at the pipe connection.
Is the water in the first-class goods, in order to sort the copper chemical activity is very low, but also by hydrogen, and stable performance, easy corrosion. According to relevant data, copper can inhibit the growth of bacteria, and keep the drinking water clean and sanitary.Advantages: high strength, stable performance, bactericidal, and not easy to corrosion.Disadvantages: high prices, difficult construction, cold in the winter, it is easy to cause heat loss, energy consumption, high use costs.
As a new type of water pipe material, PPR tube has the advantages of being healthy and non-toxic. It can be used either as a cold water pipe or as a heat pipe,Advantages: moderate price, stable performance, heat insulation, corrosion resistance, smooth wall, no fouling, piping system is safe and reliable, not penetration, the service life of up to 50 years.Disadvantages: but it needs special tools when connecting. The connecting surface needs heating. The heating time is too long or the socket is inserted too much, it will cause water blockage.
