Copper tubes are hard, not easy to corrode, are resistant to high temperatures and high pressures, and can be used in a variety of environments. In comparison, the shortcomings of many other pipes are obvious. For example, galvanized steel pipes, which were commonly used in residential buildings in the past, are easily corroded. After a short period of use, the tap water will turn yellow and the water flow will become smaller. The strength of some materials will rapidly decrease at high temperatures, which may cause unsafe risks when used in hot water pipes. The melting point of copper is as high as 1083 degrees Celsius, and the temperature of the hot water system is insignificant to copper pipes.
