An electromagnetic hot-melt pipe fitting, one end of the socket is connected to the PSP steel-plastic composite pipe by electromagnetic double hot-melt, and the other end is connected to the PP-R pure plastic fitting by single hot-melt socket. The connection between the PSP steel-plastic composite pipe and the PP-R pure plastic fitting is realized through this electromagnetic hot-melt pipe fitting. The pipe fitting and the pipe are made of the same material, and the double-layer hot-melt seal of the socket is first used. Not only are the pipe and the pipe fitting melted into one, but the pipe fitting also tightly wraps the end face of the pipe to prevent the steel strip layer on the end face of the pipe from contacting the liquid medium and rusting. The pipe fitting has a copper bushing as the inner wall protection, so that the inner wall shape of the pipe connection is complete, and the inner wall will not be deformed or reduced due to the heating of the pipe, which does not affect the water flow of the pipe, and the head loss is small. The socket end of the pipe fitting adopts electromagnetic double hot-melt connection, which is easy to install, easy to construct, and has high work efficiency.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The utility model is provided with an elbow body, a bending part, a fixing part, an arc strip, a thread and a nut. When in use, the end of the pipe is inserted into the fixing part and tightly fitted with the bending part. Then the nut is placed on the thread and rotated to squeeze the arc strip so that the arc strip and the pipe are tightly fitted, thereby completing a quick and efficient connection between the elbow and the pipe. There is no potential danger and it is safe to use.

[0016] (2) The utility model provides barbs, and as the nut gradually moves to the top of the barbs, the barbs will pierce the outer surface of the pipe, thereby increasing the connection strength between the arc strip and the pipe, achieving the purpose of preventing it from falling off.
