Do you know the difference between cold water pipe and hot water pipe? below Charlotte water pipe I will tell you in detail so that you can distinguish.

1. Stress intensity

Due to the different materials and stress intensity of water pipes, the hot water pipes can be broken with a hammer, but the cold water pipes may become white due to the force, flatten and not crack. Of course, this does not include that some businesses add a large amount of limestone powder in production to reduce costs, resulting in the decline of the strength of water pipes, and even the cold water pipes can be broken with a hammer.

2. Use environment

The hot water pipe is made of PP-R material, which has good stability and mechanical properties at high temperature, is brittle at low temperature, and is easy to be damaged. The cold water pipe made of PP-B material has good toughness at low temperature, but if the load thermal deformation temperature is low; If used at high temperature, it is easy to deform and its strength will be greatly reduced.

3. Materials

Hot and cold water pipes are mostly used in homes. Because of the difference in use environment and temperature, the production materials of the two pipes are also different. The production materials used to manufacture hot water pipes need to be copolymerized PP-R, while the production materials used to manufacture cold water pipes are mostly homopolymer PP-B.

4. Performance

Under the same specification of hot and cold water pipes, the pipe wall thickness is also the same. How to distinguish between hot water pipes and cold water pipes? Generally, the water in the cold water pipe is lower than the freezing point, which can be naturally thawed in cold conditions, but cannot be beaten or baked. Therefore, in order to avoid the cracking and cracking of the water pipe, under normal conditions, the exposure of the water pipe should be avoided as far as possible, so that the service life of the water pipe will not be affected. In addition, in the process of design, the performance of the assembly line needs to be greatly used.

5. Price

Because the pressure requirements of hot water pipe and cold water pipe are different when they are used, the wall thicknesses of the two kinds of water pipes are also different; Similarly, because the wall thickness of the two kinds of water pipes is different, the price is also different. The wall of the hot water pipe is thicker than that of the cold water pipe, so Water pipe price Relatively higher.
