Abstract

L'invention concerne un élément de moule servant comme bague d'étanchéité utilisé dans la jonction entre l'extrémité femelle d'un tuyau et l'extrémité mâle d'un autre tuyau. Un élément de moule selon l'invention comporte un corps 21 en matière cédant élastiquement, un élément de renforcement rigide non élastique 22 noyé dans le corps, le corps comportant une partie d'étanchéité 23, un bec 28, une partie extérieure arrondie 27 et une surface extérieure 25 inclinée formant un bord avant 26 avec une surface intérieure 24 se raccordant avec la surface d'étanchéité 23. L'élément de moule servant comme bague d'étanchéité convient en particulier pour des tuyaux de grand diamètre pour le transport d'un fluide sous pression.Disclosed is a mold element serving as a sealing ring used in the junction between the female end of one pipe and the male end of another pipe. A mold element according to the invention comprises a body 21 of elastically yielding material, a rigid non-elastic reinforcing element 22 embedded in the body, the body comprising a sealing part 23, a spout 28, a rounded outer part 27 and an inclined outer surface 25 forming a leading edge 26 with an inner surface 24 connecting with the sealing surface 23. The mold member serving as a sealing ring is particularly suitable for large diameter pipes for the transport of a pressurized fluid.
