PE pipe and PPR pipe are commonly used water supply pipes, and their functions are basically the same. Therefore, some people may need to connect these two kinds of pipes together because of some special circumstances, but they are not sure whether these two kinds of pipes can be connected, the following is the correct way to weld PE pipe and PPR pipe: First of all, it is certain that the PE pipe It can be connected with PPR pipe, but cannot be directly hot-melt connection. PPR pipe can be hot-melt connection, but if it is butted with PE pipe, hot-melt connection cannot be used. Now many people know that these two kinds of pipes are connected by hot-melt connection. They think that if the PE pipe and the PPR pipe are butted, they can be directly heated and connected, but in fact this method is wrong, and there is no connection strength. There is no guarantee of project quality. Because the molecular structure of the two pipes is different, even though they appear to be connected on the surface, no force is actually generated inside. The correct docking method is to use flanges for connection, and small-diameter PE pipes can also be connected with toothed accessories, so as to effectively ensure the connection strength and ensure the quality of the project.
