Some say, 16 and 6, and some say 16 and 10, and I do not know which one to sell
16/6 for refrigerators, 16/10 for hot and cold air conditioners.The copper pipe combines the advantages of metal pipe and nonmetal pipe. It is hard plastic pipe, high strength with metal (steel cold drawn tubes with same intensity of wall thickness; equivalent) it is generally flexible metal, and good toughness, with anti vibration, impact resistance and frost resistance performance.
Brass can withstand extreme heat and extreme cold temperatures from 196 degrees to 250 degrees wide application range, and adapt to the drastic changes in temperature (high temperature low temperature and high - Performance), the use will not decrease due to dramatic changes in temperature and long-term use, will not produce the aging phenomenon. This is what ordinary pipe can not do.The linear expansion coefficient of copper tube is very small. It is 1/10 of plastic pipe. It can resist fatigue. At temperature changecopper pipe
Excessive thermal expansion and cold contraction will not result in stress fatigue cracking.These characteristics make copper tube extremely advantageous in cold area. In the cold area, the temperature difference between the morning and the evening is large, and the linear expansion coefficient of the common pipe is large and the strength is low. It is easy to produce stress fatigue cracking due to thermal expansion and contraction. Some so-called -20 degrees, but can not bear the pressure of work, and the service life is short, do not have the practical significance, although can use insulation measures, but in the transportation, storage and installation process encounter cold is difficult to avoid, and brass performance is the same in -183 and at ambient temperature.
