The 90° electrofusion elbow is one of the ways of electric hot-melt connection of the steel mesh skeleton polyethylene composite pipe. The composite pipe is inserted into the 90° electrofusion elbow, and the heating wire pre-buried on the inner surface of the pipe is energized to heat it. First, the inner surface of the 90° electrofusion elbow is melted to produce a melt, and the melt expands and fills the gap of the pipe fitting until the outer surface of the pipe also produces a melt, and the two melts are fused together, and after cooling, the pipe is cooled. It is tightly connected to the pipe.
