Effect of copper pipe on building water supply pipe
Copper tube can be in the temperature between - 200 ℃ and 200 ℃, it is not easy to produce bending phenomenon, small deformation, it will not burn in case of open fire, it will not release toxic gas in case of heat, and it has good heat resistance in the extreme temperature range of cold and hot water.
Any kind of pipe has the phenomenon of thermal expansion and cold contraction, copper pipe is no exception, but compared with other materials, the linear expansion coefficient is much smaller. The linear expansion coefficient of copper tube is 0.018 mm / m · K. when the temperature rises by 60 ℃, the copper tube with 1 m length will increase by 1 mm. In a certain length of straight pipe, the temperature rise will cause thermal stress in the pipe, resulting in the damage of the pipe interface or support.
