Abstract: front page image
(EN)A deformable mechanical pipe coupling is disclosed. The coupling has a plurality of interconnectable segments that straddle the ends of pipe elements to be joined. The segments have arcuate surfaces that engage outer surfaces of the pipe elements. The outer surfaces subtend an angle of less than 180° and have radii of curvature greater than the radii of curvature of the pipe element outer surfaces. The segments have adjustably tightenable connection members for connecting the segments to one another. When the connection members are tightened, the arcuate surfaces deform and conform to the radius of curvature of the outer surface of the pipe elements.
(FR)Présentation d'un raccord mécanique déformable de tuyauterie. Le raccord a plusieurs segments interconnectables qui font chevaucher les extrémités des éléments de tuyau à raccorder. Les segments ont des surfaces précises qui s'engagent sur les surfaces externes des éléments de tuyau. Les surfaces externes sous-tendent un angle de moins de 180° et ont rayon de courbure plus grand que le rayon de courbure des surfaces externes de l'élément de tuyau. Les segments disposent d'éléments de raccordement avec serrage réglable pour le raccordement entre deux segments. Lorsque les éléments de raccordement sont serrés, les surfaces précises se déforment pour se conformer au rayon de courbure de la surface externe des éléments de tuyauterie.
