<p>PURPOSE: An electric fusion piping device using a conductive plastic cylinder is provided to improve the fusion efficiency by fusing an auxiliary fusion cylinder and a synthetic resin pipe at the face contact state. CONSTITUTION: An electric fusion piping device using a conductive plastic cylinder comprises a conductive plastic cylinder(300), an auxiliary fusion cylinder, and an electric connection terminal(400). The conductive plastic cylinder is made of conductive plastic material heated by electricity. The auxiliary fusion cylinder is fused on a synthetic resin pipe by heating of the conductive plastic cylinder. The auxiliary fusion cylinder is face-contacted to the conductive plastic cylinder and the synthetic resin pipe. The electric connection terminal is arranged along the shaft direction of the conductive plastic cylinder to supply the electricity to the conductive plastic cylinder. The electric connection terminal is line-contacted to the conductive plastic cylinder.</p> |
