The following are the principles and key points of PPR water pipe selection. Sanitary performance: No matter what material the water pipe is, the first thing to ensure is the hygienic performance, because water is used every day. If there is no guarantee on the hygienic performance, then even a small problem will be harmful to people over time. bodily harm. Product life: If the life of the water pipe is not long, then its later maintenance and loss will be several times more than the cost of the first decoration. Therefore, try to choose a water pipe that is as long as the life of the building. Flexibility: Many water pipes leak due to external forces. If the water pipes have a certain degree of flexibility, they will not be easily brittle when subjected to force. It also avoids the problem of water leakage. Corrosion resistance: Because the water flow itself will have a corrosive effect on the water pipe, especially the acid and alkali substances in the water or the oxidation corrosion in the air. Therefore, the water pipe must have corrosion resistance, which can reduce the leakage of water, and also avoid bringing impurities into the water during the corrosion process, causing pollution. Economic performance: The economic performance of water pipes is from a long-term perspective, so it must be considered comprehensively. First, the funds for the first purchase, and the second is the funds for routine maintenance. Because of the long use time, it is recommended to use high-quality products when purchasing water pipes. Although the first purchase will be slightly more expensive, the maintenance funds in the future can be greatly reduced. Construction performance and thermal expansion: The construction performance is that the selected water pipe is relatively simple in construction, easy to install, and the interface is tight. Thermal expansion is the problem of thermal expansion and contraction of water pipes. If the thermal expansion coefficient is large, it is more dangerous at low temperature and high temperature. The thermal expansion coefficient of a good product should be relatively small, and the stability is very good.
