All About the Electrofusion And its Features You Must Know
Electrofusion is a method of joining MDPE, HDPE, and plastic pipes. The pipes are joined using fittings such as valves, tees, and elbows. The conventional fusion methods are butt, saddle, and socket. In this method, the pipes and pipe surfaces are heated up with heating equipment. The electrofusion is done by heating the pipes internally with a conductive polymer or conductor at the joints. When an electric current is passed the conductive material in the pipe gets heated up. Electrofusion couplings are used when PE pipes are joined. The fittings that are welded have fusion time mentioned on them through bar code. The electrical energy is supplied to heat the coil which expands the material adjacent to it. This expanded material and the pipe surface come into contact with each other. The melting of the surface of the pipes and the material mix cause a weld. The pipe is left to cool to strengthen the joint. The strength of the electrofusion is decided when the surfaces to be welded ha
