Protection matters of PPR tube in summer

Many users may know the things to pay attention to when using PPR tubes in winter, but it is often easy to ignore the summer months. IFAN summarizes some common phenomena and countermeasures, so that you can use the pipeline in summer with more peace of mind.

PPR pipe wall "sweating" is usually not a quality problem, but because of high summer temperature, high air humidity and high water vapor content. After the water vapor encounters the lower temperature PPR pipe wall, it will liquefy and adhere to the surface of the pipe. If the ambient temperature is higher, the temperature difference with the pipe wall is larger, and the water droplets will be more. The most fundamental way to avoid the "sweat" of the water pipe is to avoid the direct contact of the water pipe with moist air to prevent liquefaction; or to 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 the water pipe is to be installed, it can be installed in a dark and low temperature place, which can also effectively overcome the phenomenon of liquefaction.

It should also be noted that in a high temperature environment, do not stack PPR tubes outdoors for a long time. The raw material of the PPR tube is polypropylene, and the polypropylene material is afraid of ultraviolet rays, so the aging of the PPR tube will be accelerated under the scorching sun in summer, so pay attention to it. PPR pipe has good corrosion resistance and can be buried concealed. However, if the objective reason is unavoidable to be in contact with the sun, the following measures can also be taken: apply special anti-radiation material on the surface of the pipe; wrap the exposed water pipe with black sunscreen foam; cover it with a dark protective layer, etc. In short, try to avoid long-term direct contact with sunlight.
