RACCORD DE BRANCHEMENT EN CHARGE, RESISTANCE ELECTRIQUE POUR UN TEL RACCORD ET SON PROCEDE DE FABRICATION

摘要

The attaching tube (18) terminates in a seat (20) made of thermoplastic material, inside which is made an annular recess (23) around the orifice (22) of the tube. In this recess is fixed a correspondingly shaped electrical resistance (14) which slightly juts out. This resistance consists of a sheathed metal wire bent at its centre, wound into a spiral and then heated in order to solder together all the turns so as to construct a flat coil with almost smooth faces. Application to the pressure branching onto conduits made of thermoplastic material.
