An electric fusion piping device is provided to obtain pressure required for fusion by pressing a melting portion molten by a heater and to improve fusion efficiency by breaking an interface layer formed by impurities. An electric fusion piping device has a pipe joint portion(100) made of a synthetic resin material. The piping device is a valve or a branch header. The pipe joint portion has a peripheral surface on which a connection screw thread(120) is formed. The pipe joint portion has an inner surface on which a ring type heater(300) for electric fusion is arranged. The electric fusion piping device includes a press member(200) having a screw joint portion(220) and a press portion(210). The screw joint portion is screw-coupled to the connection screw thread, and the press portion presses the ring type heater by advancing in accordance with the rotation of the screw joint portion. |
