Copper plays a subtle role in our daily lives. Copper can be used to transport water, power the internet, improve meals, and transmit power to automobiles. Copper is the invisible force behind connectivity, convenience, and safety, making our every day better because of it.
Stable and safe copper pipe performance
Copper is chemically stable, combining cold, heat, pressure, corrosion and fire resistance (copper has a melting point of 1,083 degrees Celsius) in a single unit, allowing it to be used for long periods of time in a variety of environments. The service life of copper pipe can be as long as the life of the building, or even longer, for example, the Peking Union Medical College Hospital in the 1920s installed copper plumbing parts after more than 70 years, is still good performance.
It can be seen that copper pipe is fully tested by more than a hundred years of time and practical experience. Copper pipe is safe and reliable. Copper pipe combines the advantages of metal pipe and non-metal pipe. It is harder than plastic pipe, with high strength of general metal (cold-drawn copper pipe strength and the same wall thickness of the steel pipe); it is easier to bend than the general metal, good toughness and high ductility, with excellent anti-vibration, impact resistance and anti-freezing and expansion performance.
Copper tube can withstand large temperature differences
The linear expansion coefficient of copper pipe is very small, is 1/10 of the plastic pipe, can resist fatigue. It will not produce excessive thermal expansion and contraction during temperature change and lead to stress fatigue rupture.
These characteristics make the copper pipe in the cold areas of the application is very advantageous. Cold areas have a large temperature difference between morning and evening, the linear expansion coefficient of ordinary pipe and low strength, very easy to produce due to thermal expansion and contraction of stress fatigue rupture. Some claim that -20 degrees is not brittle, but in fact can not withstand the working pressure, and the service life is very short, does not have practical significance, although you can use thermal insulation measures, but in the transportation, storage and installation process is difficult to avoid encountering low temperatures, and the performance of the copper pipe at -183 degrees and room temperature is the same.
