Advantages of copper tubes

The copper tubes have a hard texture, is not easy to corrode, and is resistant to high temperature and high pressure, and can be used in various environments. U poređenju sa ovim, očigledni su nedostaci mnogih drugih cijevi. Na primjer, the galvanized steel pipes used in the past are very easy to rust, and the problems such as yellowing of the tap water and small water flow will occur after a short time. The strength of some materials will decrease rapidly at high temperatures, which will cause hidden dangers when used in hot water pipes. The melting point of copper is as high as 1083 stepen celzijus, a temperatura sistema tople vode je zanemariva za bakarne cijevi. Arheolozi su otkrili bakarnu cijev za vodu 4500 godine u egipatskim piramidama, koja se i danas može koristiti.
Copper tube is durable
The chemical properties of copper are stable, and the characteristics of cold resistance, heat resistance, pressure resistance, otpornost na koroziju, and fire resistance (the melting point of copper is up to 1083 stepen celzijus) are integrated into one. It can be used for a long time in different environments. The service life of copper pipes can be as long as the service life of buildings, or even longer

Copper tube is safe and reliable
Copper pipes combine the advantages of metal pipes and non-metal pipes. It is harder than plastic pipes and has a high strength of general metals (the strength of cold drawn copper pipes is equivalent to steel pipes of the same wall thickness); it is also more flexible than ordinary metals, has good toughness and high ductility, and has excellent vibration resistance and resistance. Impact and frost heave resistance.
Copper tubes can withstand extremely cold and extremely hot temperatures, with a wide range of application from -196 degrees to 250 degrees, and adapt to drastic changes in temperature (—high temperature—low temperature—high temperature—), and the performance will not be changed due to long-term use and drastic temperature change The reduction will not cause aging. This is beyond the reach of ordinary pipes.
The linear expansion coefficient of the copper pipe is very small, which is 1/10 of the plastic pipe, and it can resist fatigue. When the temperature changes, it will not cause excessive thermal expansion and contraction, resulting in stress fatigue cracking.
These characteristics make the application of copper pipes in cold areas extremely advantageous. The temperature difference between morning and night is severe in severe cold areas, the linear expansion coefficient of ordinary pipes is large and the strength is low, and it is easy to produce stress fatigue cracking caused by thermal expansion and contraction. Some claim that -20 degrees is not brittle, but in fact can not withstand working pressure, and the service life is very short, has no practical significance. Although heat preservation measures can be adopted, it is inevitable to encounter low temperatures during transportation, storage and installation, and copper The performance of the tube is the same at -183 degrees and normal temperature.
