PPR pipe has now been widely used in all aspects of engineering and life, but many users still have a lack of understanding of PPR materials and products, so they have many questions. If you want to use PPR pipe fittings correctly and improve the comfort of home life, you must have a clear understanding of it. Here, Yifan summarizes some of the questions that users often ask, and summarizes them for everyone.

About the specifications of PPR pipe
At present, our common PPR water pipes in the market are usually 25mm (commonly known as 6-point pipe) and 20mm (commonly known as 4-point pipe), which are commonly used specifications in home improvement, of which 6-point pipes are used more. Generally, the specifications, wall thickness and other information of the pipe will be marked on the pipe wall, and the user can choose according to the information and actual needs.
About the distinction between hot and cold water pipes
The difference between hot and cold water pipes is also a question that is often talked about. On the pipe wall, the hot water pipe is generally marked with a red line, and the cold water pipe is marked with a blue line. Hot water pipes are thicker than cold water pipes, have better pressure and high temperature resistance, and are more stable in high temperature environments, but will be brittle at low temperatures and have a certain probability of damage; cold water pipes are similar to On the contrary, the toughness is good at low temperature, but the strength is greatly reduced at high temperature, and it is easy to deform. In non-extreme cases, the hot water pipe can be used as the cold water pipe, but the cold water pipe cannot replace the hot water pipe.
About the color of PPR pipe
Pure PPR raw material is actually colorless and transparent, but if the water pipe is also colorless and transparent, during use, without covering the light, algae and bacteria will breed in the pipe, thereby polluting the water quality, accelerating the aging of the water pipe, affecting the Pipe life. Therefore, manufacturers will use color masterbatch to color water pipes to enhance the anti-oxidation and light stability of pipes. The difference in color is not directly related to the quality of the pipe.
About the properties of PPR materials
In terms of comprehensive performance, PPR pipe has the advantages of light weight, good heat resistance, strong corrosion resistance, low thermal conductivity, small pipeline resistance, firm pipeline connection, hygienic and non-toxic, etc. It is a relatively cost-effective pipe, so it is widely used. Use, become the preferred material for home improvement plumbing.
About water pipe welding
The welding of pipe fittings affects the service life of the water pipe, which is very important. Water pipes generally use hot-melt welding technology, and use professional hot-melt equipment to heat the pipes and fittings to about 260 °C before connecting.
PPR pipe are more and more used and have become an indispensable part of many people's homes. We are also committed to providing customers with high-quality PPR pipe fittings and other products with a rigorous attitude and the concept of excellence.
