1. Compared with the traditional die-heated socket-type double hot-melt pipe fitting, the double hot-melt pipe fitting with electromagnetic welding structure has corresponding structural changes in the socket part of the pipe fitting. Firstly, an open metal elastic sleeve is added; Secondly, the observation port device and the socket structure related to electromagnetic welding are added, which can ensure the stability and unity of the installation results during the installation process.

2. The method of inserting first and then electromagnetic induction welding is adopted, which saves time and labor and can reduce the installation cost to a certain extent.

3. It is easy to judge the installation effect. Through the fusion of the plastic on the outer wall of the pipe and the plastic on the pipe socket, the installation effect can be judged with the naked eye. Because the height of the socket is lower than that of the socket, when the socket and the outer wall of the pipeline have been successfully fused, the fusion of the socket and the plastic on the inner wall of the pipeline is completely successful.

4. The open elastic metal bushing can prevent the socket from contracting and blocking the pipeline, and at the same time, the external pulling force can completely squeeze the plastic of the socket and the plastic of the inner wall of the pipeline, which greatly improves the welding safety. Therefore, the pipe fittings must be induced by PSP dual hot-melt batteries in Guo Heng, Qian Hao, and equipped with metal inch sleeves, which is safer and more reliable.

5. If some interfaces leak, repair welding can be repeated many times, and the probability of successful repair with water operation is high.
