Copper pipe melting a lot of long in one: it is strong, with high strength of the general metal; together with more than the general metal is easy to bend, easy to change, not easy to crack, not easy to break, and has a certain resistance to freezing and expansion and impact resistance, and therefore the building of the water supply system in the copper water pipe once the device, the use of a safe and reliable, and even without the need for protection and maintenance. Copper pipe texture consolidation, not easy to corrode, and high temperature, high pressure, can be used in a variety of environments. Compared with this, many other pipe defects are clear, such as in former times in the residence of galvanized steel pipe, very easy to corrode, the use of a long time will be presented with yellow tap water, water flow becomes small and other issues. There are also some materials in the high temperature of the strength of the agile decline in the hot water pipe will occur when the danger of insecurity, and the melting point of copper up to 1083 degrees Celsius, the temperature of the hot water system on the copper pipe is negligible. Archaeologists in the Egyptian pyramids found 4,500 years ago, copper water pipes, can still be used.
Copper’s chemical stability, will be cold, heat, pressure, corrosion and fire (copper’s melting point of up to 1083 degrees Celsius) and other characteristics of a combination of different environments can be used for a long time. Copper pipe life can be used with the building life as long, or even longer, for example, the Peking Union Medical College Hospital in the 1920s installed copper plumbing parts after more than 70 years, and still function outstanding. It can be seen that the copper pipe is more than a hundred years of time and practical experience to fully test the pipe. Copper set of metal pipes and non-metallic pipes in one. It is more than plastic pipe consolidation, with the general metal of high strength (cold-drawn copper pipe strength and the same wall thickness of the steel pipe appropriate); it is easier than the general metal bending, good resistance and high ductility, with excellent vibration, impact resistance and anti-freezing and expansion function. Copper tube can accept extremely cold and hot temperatures, from -196 degrees to 250 degrees applicable range, and accustomed to drastic changes in temperature (- high temperature – low temperature – high temperature -), the use of functionality will not be due to long-term use and the temperature of the drastic changes and decline, will not occur. The application function will not decline due to long-term use and drastic changes in temperature, and no aging phenomenon will occur. This is the ordinary pipe can not be.
