[0002] At present, water pipes are pipes for water supply. Modern decoration water pipes are all constructed by wall-embedded construction. There are three types of water pipes. The first type is metal pipes, such as hot-dip cast iron pipes, copper pipes, stainless steel pipes, etc. lined with plastic. The second type is plastic-clad metal pipes, such as steel-plastic composite pipes, aluminum-plastic composite pipes, etc. The third type is plastic pipes, such as PB pipes, PP-R pipes, etc.
[0003] The density of ice is smaller than that of water. When water freezes, its volume expands by 10%. When the water pipe freezes, it becomes a closed container. When water freezes, its volume expands. The pressure generated cannot be transferred through the pipe. It must break through the weakest point of the pipe to release the pressure, causing the pipe to burst.
