How does copper water pipe resist corrosion?

1： Sanitation and sterilization

The traditional galvanized steel pipe will rust after being used for a period of time. Rust contaminates drinking water and provides shelter for harmful bacteria. In contrast, the protective film on the surface of the copper pipe has a good protective effect, the copper pipe wall will not rust, and the free copper ions in the water also have a strong disinfection and sterilization effect. Scientific experiments have proved that more than 99% of bacteria in water will be killed when entering the copper pipe, and the copper pipe is sealed and impermeable, which can effectively prevent the entry of harmful substances and ensure the safety of drinking water. Copper is an indispensable trace element for human health. Among the basic elements required by the World Health Organization, the demand for copper is 2 mg / day. Therefore, when the copper pipe is applied to the water supply system, the trace copper ion in the water is safe and beneficial to the drinkers.

2： Durable

Thousands of years ago, people began to use copper as a tool of life and production, the important reason is that copper has a good durability. Although a variety of new materials are emerging in the field of building decoration, there is no unique material that integrates heat resistance, fire resistance, pressure resistance and corrosion resistance. The chemical properties of copper are quite stable and not easy to be corroded. The strength of copper pipe is much higher than that of plastic pipe and can bear considerable pressure. Compared with steel pipe and copper pipe, its toughness is better, and it will not crack and break under strong frost heaving and impact. The melting point of copper is as high as 1083 degrees centigrade, so the temperature of hot water is no less important for copper pipes. Copper pipe is not only solid and dense, but also has a protective film on its surface which is not dissolved by medium. No matter oil, carbohydrate, bacteria and virus, harmful liquid, oxygen or ultraviolet ray can pass through it and then erode the pipe wall; parasites can not live on the surface of copper to soften it.

3： Beautiful and practical

Copper has the characteristics of strong and durable. The finished pipe has a beautiful shape and will last forever. The various shapes of copper pipes can bring users a gorgeous feeling, which is incomparable with other water heating pipes. In modern home decoration, we attach great importance to the appearance of pipes. The use of copper pipe material as water pipe can improve the quality and add luster and color. In addition, due to the thin wall of copper pipe, the inner pipe diameter is larger. When used as wall type water pipe device, it can reduce the depth of hollowed wall, and indirectly contribute to the increase of space and beauty of living room.

In addition, copper is one of the few colored metals. Copper and its alloy can be orange red, golden yellow, green, silver white and other colors. Copper is also very compatible with other alloys. Nickel, silver and gold can be plated on the surface according to the user's personalized requirements to achieve different decorative effects.
