As mankind's earliest understanding and use of metal, copper in ancient Egyptian hieroglyphics is a cross with a circle "♀" on behalf of "eternal life."
Copper pipe in the building has a long history of application, is recognized by more than a century of time and practical experience fully tested the performance of the pipe, as a water supply pipe, heating pipe and gas pipe, etc., unique charm. At present, the field of mixed pipes, a moment of indistinguishable, copper pipe can really distinguish itself from the other pipe's biggest feature is the above sentence: copper pipe is recognized by more than a hundred years of time and experiments fully tested by the performance of the pipe.
This statement can be proved by the following main advantages of copper pipe:
1, durable - the chemical properties of copper is stable, will be cold, heat, pressure, corrosion and fire resistance and other characteristics in one, can be used in different environments for a long time. For example, the Ruijin Hotel and Union Hospital in the use of copper after 80 years, can still be intact performance.
2, safe and reliable - copper pipe set of metal and non-metallic pipe advantages in one. It is harder than plastic, with high strength of general metal. It is easier than the general metal bending, good toughness and high ductility, with excellent vibration, impact and frost resistance.
Copper pipe can withstand -196 degrees to 205 degrees temperature range, and adapt to high and low temperature drastic changes in performance will not be reduced due to long-term use, will not produce aging phenomenon. Therefore, the strong resistance to low-temperature brittleness of copper pipe is especially suitable in cold areas.
3, health - biological research shows that: the water supply in the E. coli in the copper pipe can not continue to reproduce; more than 99% of the bacteria in the water into the copper pipe 5 hours after being completely killed. This outstanding biological performance is because there are trace amounts of copper dissolved in the water and the formation, and the human body through the drinking water intake of copper is also beneficial to health (copper is an indispensable trace element in the human body).
The performance of copper pipes can be the same at -180 degrees as at room temperature.
Therefore, the strong resistance to low-temperature brittleness of copper pipe in the cold heating area is particularly suitable for the region. The current advocacy of sub-division of metering and concealed design more need for copper pipe safety and reliability, low coefficient of thermal expansion and other superiority.
At the same time, the sub-household plan will shift the burden of heating costs from the state to the market-oriented property management sector, so that the system (radiators + piping) life, safety, cost and other issues will be much higher than ever before by the importance of.
The superior performance of copper radiators enables systems to achieve lower maintenance costs and a higher service life.
