<p>PROBLEM TO BE SOLVED: To provide an electric fusion type joint capable of facilitating the manufacturer thereof even in case of a joint having various kinds of shape and capable of easily connecting a pipe with an electrifying control controller of a normal electric fusion joint. SOLUTION: This device is formed of an electric fusion joint 1 provided with one system of heating wire embedded over from one port for insertion of a thermoplastic resin tube to be connected toward the other receiver port and a spigot joint 2 having fusing cylinder parts 21, 22 inserted into one receiver port of the fusion joint 1 and fixed to a receiver port end surface of the fusion joint by thermal fusion. In this case, at the time of fusing work, a resin pipe to be connected is inserted into the other receiver port of the electric fusion joint 1, and the heating wire is electrified for heating, and a resin pipe to be connected and the fusing cylinder parts 21, 22 of the spigot joint 2 are electrically fused at the same time.</p> |
