In any equipment and system, each part plays an important role, even if it is only one of the accessories, it is not available and plays an important role. For example, in the pipeline system, although the main material is pipe, PE electrofusion pipe fittings are only accessories, but the role of pipe fittings can not be ignored, and the performance of pipe fittings will also cause great application to the application effect of the whole pipeline system.

It is because the function of PE electrofusion pipe is very important and has application effect on the whole pipe system, so it has high requirements in many aspects, such as the requirement that the pipe fittings have a long service life. Because in the whole piping system, pipe is connected together by pipe fittings, thus forming a whole pipe system. Once there is a problem in the pipe fittings, it will cause the leakage of the pipeline, which will lead to the whole pipe system can not be used normally, and the adverse consequences are very large.

So considering that the pipe itself has a long life, it is necessary for the pipeline system to achieve long-term application, which will also have a high demand for the service life of PE electrofusion pipe. It is necessary to have a long service life in order to ensure the life of the whole pipeline system.
