Copper Tube Target Oxygen-Free Copper Pure 99.97% 155OD*125ID*888

Copper tube is hard in texture, not easy to corrosion, and high temperature and high pressure resistance, can be used in a variety of environments. Compare with this, the shortcoming of a lot of other pipe material is apparent, for instance the multi-purpose galvanized steel pipe in past residence, rust easily, use time is not long can appear tap water hair yellow, current decrescent wait for a problem. Still the intensity that some material falls in high temperature can be reduced rapidly, when be used at hot water tube can produce unsafe hidden trouble, and the melting point of copper is as high as 1083 degrees Celsius, the temperature of hot water system is negligible to copper tube. Archaeologists have found copper water pipes in the Pyramids of Egypt that are 4,500 years old and still working today.

Copper pipe has the advantages of both metal pipe and nonmetal pipe. It is stronger than plastic pipe and has the high strength of general metal (the strength of cold-drawn copper pipe is equivalent to that of steel pipe with the same wall thickness); It is more flexible than ordinary metal, good toughness and high ductility, with excellent vibration resistance, impact resistance and frost heaving resistance.
Copper tube can withstand freezing and extremely hot temperature, from -196 degrees to 250 degrees applicable range, and adapt to temperature drastic changes (- high temperature - low temperature - high temperature -), the use of performance will not be reduced because of long-term use and temperature drastic changes, will not produce aging phenomenon. This is the ordinary pipe can not reach.
The linear expansion coefficient of copper tube is very small, 1/10 of that of plastic tube, which can resist fatigue. When the temperature changes, there will not be excessive thermal expansion and cold contraction, resulting in stress fatigue rupture.
These characteristics make the application of copper pipe in cold area extremely advantageous. Cold area morning and evening temperature difference is large, the linear expansion coefficient of common pipe is large and strength is low, the stress fatigue rupture that causes expansion and contraction of heat easily. Some so-called -20 degrees is not brittle, but can not bear working pressure actually, and service life is very short, do not have practical significance, although we can use heat preservation measures, but in transport, storage and installation process is hard to avoid low temperature, and the performance of copper pipe in -183 degrees and normal temperature is the same.

Advantages:
1, high conductivity
2. Good thermal conductivity
3, good weldability
4, excellent plasticity and ductility
5, excellent cold working performance
