they are easier to bend than general metals, have good toughness and high ductility, and have excellent vibration resistance, impact resistance and frost heave resistance.

Copper pipes are safe and reliable
Copper pipes combine the advantages of metal pipes and non-metallic pipes. They are harder than plastic pipes and have 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); they are easier to bend than general metals, have good toughness and high ductility, and have 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-). 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 cause stress fatigue cracking.
These characteristics make copper pipes very advantageous in cold areas. In severe cold areas, the temperature difference between morning and evening is large, and the linear expansion coefficient of ordinary pipes is large and the strength is low, which is very easy to produce stress fatigue cracking caused by thermal expansion and contraction. Some claim that they are not brittle at -20 degrees, but in fact they cannot withstand working pressure and have a very short service life, which has no practical significance. Although insulation measures can be adopted, it is inevitable to encounter low temperatures during transportation, storage and installation. The performance of copper tubes at -183 degrees is the same as at room temperature.
