The difference between PPR cold and hot water pipes

The difference between hot and cold water pipes is also a question that is often talked about. On the pipe wall, the hot water pipe is generally marked with a red line, and the cold water pipe is marked with a blue line. Hot water pipes are thicker than cold water pipes, have better pressure resistance and high temperature resistance, and have higher stability in high temperature environments, but they will be brittle and have a certain probability of damage under low temperature conditions; cold water pipes are the opposite. , good toughness under low temperature conditions, but the strength is greatly reduced under high temperature conditions, and it is easy to deform. In non-extreme cases, hot water pipes can be used as cold water pipes, but cold water pipes cannot replace hot water pipes.
