As we all know, copper pipe has excellent resistance to high and low temperature changes. And copper pipe as a building heating pipe, as a tap water pipeline, then, how about its heat resistance? The following copper pipe quick connector,!

Good copper pipe can be in the temperature conditions between -200℃ and 200℃, to ensure that there is no bending phenomenon, no deformation, in the case of open fire does not burn, in the case of heat will not release toxic gas, in the extreme temperature range of cold and hot water, heat resistance is very good.

The influence of temperature change on the service performance of hot water pipeline mainly lies in the characteristics of thermal expansion and cold contraction and the resulting creep fatigue. In this respect, the coefficient of thermal expansion of plastic pipes is larger. Between the water supply and water shutdown of hot water pipes, the coefficient of thermal expansion of plastic pipes is ten times that of copper pipes.

Of course, any kind of pipe has the phenomenon of thermal expansion and cold contraction, copper water pipe is no exception, but compared with other materials of the pipe, the linear expansion coefficient is much smaller. The linear expansion coefficient of copper tube is 0.018mm/m·k, when the temperature rises 60℃, 1m long copper tube will increase by 1mm. In a certain length of straight pipe segment, the temperature rise will cause thermal stress in the pipe, leading to the damage of pipe interface or support.

Under normal circumstances, when the project is installed, corresponding measures should be considered in every 10m long straight pipe segment, such as the installation of expansion junction. However, in general, the straight line section is generally not more than 10m.

When installing hidden heating and hot water pipes, in order to ensure safety and safety, it is also necessary to install plastic or other material elbow sleeves at each elbow. If the open pipe does not exceed 10m, the expansion problem may not be considered.
