Copper pipes are durable Copper pipes are safe and reliable

Copper pipes are hard and not easy to corrode. They are also resistant to high temperatures and high pressures and can be used in a variety of environments. In comparison, the shortcomings of many other pipes are obvious. For example, galvanized steel pipes, which were often used in residential buildings in the past, are very easy to rust. After a short period of use, the tap water will turn yellow and the water flow will decrease. Some materials will quickly reduce their strength at high temperatures, which will cause unsafe hazards when used for hot water pipes. However, the melting point of copper is as high as 1083 degrees Celsius, and the temperature of the hot water system is negligible for copper pipes. Archaeologists have discovered copper water pipes dating back 4,500 years in the Egyptian pyramids, which are still in use today.
Copper pipes are durable
The chemical properties of copper are stable, and it combines the characteristics of cold resistance, heat resistance, pressure resistance, corrosion resistance and fire resistance (copper has a melting point of up to 1083 degrees Celsius), and can be used for a long time in different environments. The service life of copper pipes can be as long as the life of the building, or even longer. For example, the copper plumbing parts installed in Peking Union Medical College Hospital in the 1920s have been in good condition for more than 70 years. It can be seen that copper pipes are pipes that have been fully tested by more than a hundred years of time and practical experience.
Copper pipes are safe and reliable
Copper pipes combine the advantages of metal pipes and non-metallic pipes. It is harder than plastic pipes and has the high strength of general metals (the strength of cold-drawn copper pipes is equivalent to that of steel pipes with the same wall thickness); it is easier to bend than general metals, has good toughness and high ductility, and has excellent vibration resistance, impact resistance and frost heave resistance.
Copper pipes can withstand extremely cold and hot temperatures, with a wide range of applications from -196 degrees to 250 degrees, and can adapt to drastic temperature changes (-high temperature-low temperature-high temperature-), and the performance will not be reduced due to long-term use and drastic temperature changes, and will not produce aging. This is beyond the reach of ordinary pipes.
The linear expansion coefficient of copper pipes is very small, which is 1/10 of that of plastic pipes, and it is fatigue-resistant. When the temperature changes, there will be no excessive thermal expansion and contraction, which will lead to stress fatigue cracking.
These characteristics make the application of copper pipes in cold areas very advantageous. In extremely cold regions, the temperature difference between morning and evening is large. Ordinary pipes have large linear expansion coefficients and low strength, which are prone to stress fatigue cracking caused by thermal expansion and contraction. Some pipes are claimed to be non-brittle at -20 degrees, but in fact they cannot withstand working pressure and have a very short service life, which is of no practical significance. Although insulation measures can be adopted, it is difficult to avoid low temperatures during transportation, storage and installation. The performance of copper pipes at -183 degrees is the same as at room temperature.
