2.ppr materials are usually divided into cold and hot, and their colors will be marked with red and blue. The thickness of the heat pipe is greater, and the thickness of the cold pipe is greater.
What are the advantages of ppr? 1, ppr has wear-resistant appearance, frosted surface and smooth interior.
2.ppr material has smooth surface and compact structure.
3.ppr is composed of four tapes, so it is very heavy and stable.
What are the disadvantages of ppr? 1.ppr pipe requires high temperature selection, and it works at 0 ~ 70℃ for a long time, so it has weak freeze-thaw resistance and cannot withstand high temperature and high pressure.
2.ppr tube is easy to age and has poor ultraviolet resistance. Exposure to the sun for a long time will accelerate aging. If they are used for a long time, they will expand when heated and contract when cooled, resulting in deformation and expansion of products. If it is serious, it will have a great impact on our lives.
The application scope of ppr pipe is 1. Inject pure water directly into our water source.
2. It can also be used for floor heating of buildings. The other is radiant heating.
3. The water heater that we use every day can also be used.
4.ppr pipe is often used in central air conditioning.
The difference between pert pipe and ppr pipe pert pipe heating is a new type of healthy, energy-saving, environmental protection and sanitary heating method. Using the building floor as the heat dissipation surface, 60% of the heat (8 ~ 13 micron) is radiated indoors, and 40% of the heat is conducted indoors by convection, which makes the indoor temperature uniform and constant, saves the indoor space, and has certain medical and health care functions.
Generally, the service life of pert tube radiant heating system is more than 50 years (more than 50 years), and its hidden part (except human factors) can last for 50 years, which is one of the main reasons why pert tube heating system is widely used. The service life of 50 years is limited, which is mainly determined by the service life of heating pipes.
That's the ppr tube I told you about. I hope I can help you. If you don't know much about it, you can refer to the above content to learn.
