PPR pipe wall "sweating" is usually not a quality problem, but because the summer temperature is high, the air humidity is high, the water vapor content is high. When the water vapor hits the wall of the PPR pipe at a lower temperature, it will liquefy and adhere to the surface of the pipe. If the ambient temperature is higher, the greater the temperature difference with the tube wall, the more water droplets there will be. If you want to avoid water pipe "sweating", the most fundamental way is to avoid direct water pipe contact with moist air, prevent liquefaction; Or reduce the temperature difference between the pipe and the surrounding air. On the one hand can be installed insulation layer, reduce the contact with the air; If water pipes are to be installed, they can be installed in a dark and low temperature place to effectively overcome the phenomenon of liquefaction.
It should also be noted that PPR tubes should not be stacked outdoors for a long time in a high temperature environment. The raw material of PPR tube is polypropylene. Polypropylene material is afraid of ultraviolet light, so under the summer sun, it will accelerate the aging of PPR tube, so we should pay great attention to it. PPR tube has good corrosion resistance and can be hidden buried. However, if exposure to sunlight is unavoidable for objective reasons, the following measures can also be taken: Apply special radiation-resistant materials on the surface of the pipe; Cover exposed water pipes with black sunscreen foam; Use a dark protective layer covering and so on. In short, try to avoid its long-term direct contact with the sun.
The above is an introduction to the two common situations in summer use, and the most basic care of the PPR tube is also essential. PPR pipe, as a common health pipe for home decoration, has strong corrosion resistance, safety and environmental protection, and long service life, which is widely recognized by owners. As long as the corresponding protection is done well, we can make the PPR pipe play the best performance and effectively improve the quality of home decoration for users
