For forming a clamping ring (6) first the pipe is extruded. The extruded pipe is cut to form a pipe part. While extruding the pipe, its inner diameter is formed smaller than the outer diameter of a pipe (1) onto which the clamping ring is positioned before making a pipe connection. The inner diameter of the pipe part is made larger by removing material from the inside of the pipe part but only over part of the length of the pipe part such that a stop edge (7) is formed. The clamping ring is used on a pipe when making a pipe connection.
L'invention concerne un procédé de fabrication d'un collier de serrage (6), consistant tout d'abord à extruder un tuyau, puis à découper le tuyau extrudé pour former une partie tuyau. Pendant l'extrusion, le diamètre intérieur du tuyau est inférieur au diamètre extérieur d'un tuyau (1) sur lequel le collier de serrage est placé avant la fabrication d'un raccord de tuyau. Le diamètre intérieur de la partie tuyau est accru par l'élimination de matériau provenant de l'intérieur de la partie tuyau, mais seulement sur une partie de la longueur de ladite partie, de sorte à former un bord d'arrêt (7). Le collier de serrage selon l'invention est utilisé sur un tuyau pendant de la fabrication d'un raccord de tuyau.
