Device for welding an accessory on a pipe by means of electrical heating elements integrated in said accessory |
摘要 |
A device is disclosed for welding an accessory of thermoplastic material to a pipe or to two pipes of thermoplastic material to be connected to one another. The accessory has at least two segments embracing the circumference of the pipe or pipes. The segments have electrical heating elements at least over portions of their inner surfaces contacting the pipe or pipes. The segments are connected to a welding device via two electrical connecting lines. The two connecting lines form with two connector lines a line combination for a parallel electrical switching of all heating elements. The segments have at their outer surfaces two electrical coupling members for supplying and carrying away an electrical current through the line combination. Counter coupling members of the line combination are contacted with the coupling members of different segments, wherein the coupling members and the counter coupling members are different from each other and are not compatible with each other.
