At present, water pipes are mainly divided into three types, namely metal pipes, plastic pipes and plastic-coated metal pipes. The metal pipe comprises a galvanized pipe, a copper pipe, a stainless steel pipe and the like, the galvanized pipe can be corroded after being used for several years, bacteria are bred, and the galvanized pipe is not beneficial to human health and cannot be used for drinking water pipes; copper pipes and stainless steel pipes are expensive and difficult to construct. The plastic pipe comprises a PVC pipe and a PE pipe, the plastic-clad metal pipe comprises an aluminum-plastic composite pipe, and due to the fact that the types of plastics are various and the market quality is uneven, additives such as phthalein are frequently used in the production process of the plastics, cancer and kidney damage can be caused, a human body function reconstruction system is damaged, development is influenced, particularly toxic components can be volatilized at high temperature, and therefore, the plastic pipe which is safe is not easy to select as a drinking water pipe.

The silicate material is a green environment-friendly material, and products of the silicate material comprise cement, glass, enamel and the like. For example, enamel products have the advantages of corrosion resistance, high temperature resistance, low price, harmlessness, sanitation and the like, but because connection construction is inconvenient, the existing enamel pipes are mostly used for heat exchange pipes, easy-to-corrode occasions such as boiler plants, power plants and the like, and are not applied to drinking water pipes.
