The invention relates to a method for joining a plastic pipe or the like, in which method a pipe (1) is joined to another plastic pipe or sleeve (2). At least one flexible plastic-containing welding ring (6) is placed in the joint area, and energy is conducted to the welding ring for melting the plastic in the ring and for joining it with the pieces (1; 2) to be connected, whereupon the pressure required for welding the plastic is produced mainly by compressing the flexible welding ring (6) provided between the pieces to be joined. The invention also relates to a joint ring used in the joining and to a pipe joint provided with the method.
L'invention se rapporte à un procédé de raccordement d'un tuyau en plastique ou autre, procédé dans lequel un tuyau (1) est raccordé à un autre tuyau en plastique ou manchon (2). Au moins un anneau de soudure (6) contenant du plastique est placé dans la zone de raccordement, et une énergie est dirigée dans l'anneau de soudure pour faire fondre le plastique dans l'anneau et pour le raccorder aux pièces (1; 2) à assembler. La pression nécessaire pour souder le plastique est principalement produite par la compression de l'anneau de soudure flexible (6) ménagé entre les pièces à raccorder. Cette invention se rapporte également à un anneau d'étanchéité utilisé dans le raccordement et à un raccord de tuyau utilisé selon ce procédé.
