Please note that the summer PPR tube protection matters

PPR pipe wall "sweating", usually not quality problems, but because of the high summer temperature, high air humidity, high water vapor content. When water vapor meets the cooler PPR wall, it will liquefy and adhere to the surface of the pipe. The higher the ambient temperature, the greater the temperature difference with the wall, the more water droplets will be. Want to avoid water pipe "sweat", the most fundamental method is to avoid water pipe direct contact with moist air, prevent liquefaction; Or reduce the temperature difference between the pipe and the surrounding air. On the one hand, the insulation layer can be installed to reduce the contact with the air; If it is to install water pipes, can be installed in a dark and low temperature place, can also 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. PPR pipe raw material is polypropylene, polypropylene material is afraid of ultraviolet light, so in the summer sun, will accelerate the aging of PPR pipe, so we should pay attention to. PPR tube has good corrosion resistance and can be concealed and buried. However, if contact with sunlight is unavoidable for objective reasons, the following measures can also be taken: coating the surface of the pipe with a special radiation resistant material; Cover exposed water pipes with black sunscreen foam; Cover with dark protective layer and so on. In short, try to avoid long-term direct contact with the sun.
