As a commonly used pipe in home improvement and tooling, ppr tube has a high cost performance. In a normal temperature environment, the service life of ppr tube is more than 50 years. The ppr pipe, like other pipes, also has a critical temperature used.

　　One: normal pipeline

The critical operating temperature of the general ppr tube is 70 degrees. When the temperature reaches 70 degrees, the material of the ppr tube will become soft, and some parts of the hot melt connection will crack. Therefore, in floor heating, generally Use pe pipes instead of ppr pipes.

Its lowest critical temperature is about minus 10 degrees. When it is minus 10 degrees, there will be freezing and cracking when there is water in the pipeline. Before winter comes, the pipeline insulation cotton needs to be laid, so that it can be appropriately reduced. Critical temperature value.

　　 Two: Special customized pipeline

The use of ppr tube; the critical temperature is not fixed. In the process of production and research and development, when some temperature of condensation is added to the pp particles, the critical temperature of the ppr tube can be increased between 10 degrees and 15 degrees. At the same time, depending on the inner wall treatment process and the surface coating process, its critical temperature can be appropriately increased.

　　Three: Environmental classification used

In the field of home decoration, the ppr pipe is generally buried inside the wall, and its temperature generally does not exceed 50 degrees. For some ppr pipes used outdoors, in order to ensure its safety, it is generally necessary to install the pipe after the pipe is installed. Set up some corresponding protection measures.

　　Ppr tube is limited by the operating temperature, so it needs to be judged in various environments.
