ことができ、正確な施工を行うことができる。It is also conceivable to perform such fusion bonding by means of bad fusion or the like, but in the case of this fusion fusion, it is necessary to use a heater face and the work becomes complicated. , Centering and positioning cannot be performed properly. On the other hand, in the case of the electro-fusion member 1 of the present invention, the welding can be performed by a simple work such as energizing the coil 3, and after the centering and the positioning of the flange tube 4 are firmly adjusted, the fusion welding is performed. It can be done and accurate construction can be done.

However, the flange tube 4 is not particularly limited as long as it has the thermoplastic resin layer 42 on the flange surface 41. For example, the entire metal tube 43 having the flange surface 41 may be coated with a thermoplastic resin, or the entire flange tube 4 may be formed of a thermoplastic resin.

By melting and integrating with the thermoplastic resin layer,
A watertight state can be secured.
