An elastomeric flange lining is provided for the metal flange of a pipe, the flange lining being structured with an annular channel with allows lateral movement of the elastomeric material of the flange lining when the flange lining is subjected to high compression forces, such as when two pipes are joined togetherend-to-end at their respective pipe flanges. The design of the flange lining andmanner in which the flange lining is produced prevents outward bulging of elastomeric material into the interior of the pipe when subjected to compressionforces. A flange mold for forming the flange lining is disclosed, and the methodof making the flange lining is also disclosed.
Garniture élastomérique pour bride de tuyau métallique, la garniture de la bride présentant une structure à rainure annulaire destinée à permettre le déplacement latéral du matériau élastomérique lorsque la garniture de la bride est soumise à d'importantes forces de compression, comme celles qui sont générées lors de l'assemblage de tuyaux à l'aide de brides. La configuration de la garniture de la bride ainsi que la façon dont elle est produite préviennent le mouvement de déformation du matériau élastomérique vers le diamètre intérieur du tuyau sous l'effet des forces de compression. Un moule pour la fabrication de la bride ainsi que la méthode de fabrication de la garniture de la bride sont également dévoilés.
