Summer PPR water pipe maintenance manual, be sure to take sun protection measures!

- Oct 08, 2020-

PP-R water pipe is a commonly used water pipe material in many home decorations. It has strong corrosion resistance, safety and environmental protection, and long service life, and has been universally recognized by owners. Most users pay attention to the winter protection of PP-R pipes, but ignore the summer protection.

In fact, protection in summer is equally important. If the PP-R pipe is placed outdoors for a long time, it may become brittle. This is because of the raw material characteristics of plastic pipes. Polypropylene materials are afraid of ultraviolet rays and will accelerate the aging of PP-R pipes under the sun, so summer protection cannot be ignored!

Summer protection tips for PP-R water pipes

1. Anti-radiation coating

Applying special anti-radiation paint on the surface of the pipe can effectively protect the PP-R water pipe.

2. Sunscreen film

Wrap the exposed water pipe with a black sunscreen foam film.

3. Lightweight aluminum foil glue

It can be pasted with lightweight aluminum foil tape, which has good adhesion, strong adhesion and anti-aging. It is more beautiful than black sunscreen, but the cost is slightly higher.

4. Dark protective layer

PP-R pipes are prone to aging and degradation when exposed to ultraviolet rays for a long time. They must be covered with a dark protective layer when installed outdoors or in direct sunlight.

5. Burial

The PP-R pipe is concealed. Under normal circumstances, the pipe can be concealed. The PP-R pipe has good corrosion resistance and will not be corroded after being buried in the ground. It can not only protect against sun, but also prevent freezing in winter.

Why does the surface of PP-R pipe "sweat" in summer

Summer is coming, and the temperature gradually rises. Some careful users will find that the surface of their own PP-R pipes will have some small "sweat" like our human body. In some areas with higher temperature, PP-R may even appear. Pipe the phenomenon of "leakage". Is it possible that your own PP-R pipes are more likely to leak in summer? Not really.

In fact, the "perspiration and leakage" on the surface of water pipes in summer is not a quality problem of PP-R pipes, but is caused by the high temperature and high humidity in the air in summer.

PP-R pipes don’t sweat much in summer. "Sweating" is because the summer temperature is high, the air is humid, and the water vapor content is high. When encountering a low temperature PPR pipe body, it will liquefy and the water vapor will condense. The formed water adheres to the surface of the PP-R pipe. The greater the temperature difference between the surface of the pipe and the air temperature, the more water drops will occur, and some so-called "sweating" phenomenon will appear. When the "sweating" increases, it is not clear The user will think that there is a leak in the water pipe, which is actually a phenomenon of water vapor liquefaction.

Here is a little trick. If the pipe wall "sweats" a lot, it means that the water vapor content in the air is higher and the humidity is higher, which is a precursor to rain.

How to avoid sweating in water pipes in summer?

Protective measures for PP-R pipes in summer are still indispensable. If you want to avoid "sweating", the most important thing is to avoid contact between the pipe body and moist air and prevent liquefaction; or reduce the temperature difference between the pipe body and the surrounding air. value.

Therefore, for the case where the temperature of the pipe body and the surrounding temperature is relatively high, the method of sleeve insulation pipe can be adopted to reduce the contact between the PP-R pipe and the surrounding air; secondly, if you do not want to sleeve insulation pipe, install the water pipe in a dark and low temperature Locally, to overcome the liquefaction phenomenon of PP-R water pipe caused by temperature difference.

Finally, the editor advises users to take sun protection measures for PP-R water pipes according to the specific situation at home, and try not to expose the water pipes to the outdoors!
