Copper pipes combine the advantages of metal pipes and non-metal pipes. It is harder than plastic pipes and has the high strength of ordinary metals (the strength of cold-drawn copper pipes is equivalent to that of steel pipes with the same wall thickness); it is more flexible than ordinary metals, has good toughness and high ductility, and has excellent anti-vibration and Impact and frost heave resistance.
Copper tubes can withstand extremely cold and extremely hot temperatures, with a wide range of applications from -196 degrees to 250 degrees, and adapt to drastic changes in temperature (-high temperature-low temperature-high temperature-), and the performance will not change due to long-term use and drastic temperature changes And reduce, will not produce aging phenomenon. This is beyond the reach of ordinary pipes.
The linear expansion coefficient of the copper pipe is very small, which is 1/10 of that of the plastic pipe, and it can resist fatigue. When the temperature changes, it will not cause excessive thermal expansion and contraction, which will cause stress fatigue cracking.

These characteristics make the application of copper pipes in cold regions extremely advantageous. In severe cold areas, the temperature difference between morning and evening is large, and ordinary pipes have a large linear expansion coefficient and low strength, and are prone to stress fatigue cracks due to thermal expansion and contraction. Some claim that it is not brittle at -20 degrees, but in fact it cannot withstand working pressure, and its service life is very short, which has no practical significance. Although insulation measures can be used, it is inevitable to encounter low temperatures during transportation, storage and installation. The performance of the tube is the same at -183 degrees and normal temperature.
