Title (EN) COUPLING SEAL HAVING RAMP SURFACES
(FR) JOINT D'ÉTANCHÉITÉ DE COUPLAGE AYANT DES SURFACES EN RAMPE
Abstract:
(EN) A seal for a coupling joining pipe elements has angularly oriented ramp surfaces on an outer surface. The ramp surfaces are arranged in diametrically opposite pairs which are positioned at the three o'clock and nine o'clock positions at the interface between segments forming the coupling. The ramps are expected to mitigate pinching of the seals between the segments as the segments are drawn together, compressing the seals to form a fluid tight pipe joint.
(FR) L'invention concerne un joint d'étanchéité pour un accouplement reliant des éléments tuyaux, lequel joint a des surfaces en rampe orientées de façon angulaire sur une surface externe. Les surfaces en rampe sont disposées par paires diamétralement opposées qui sont positionnées aux positions à trois heures et à neuf heures à l'interface entre les segments formant le couplage. Les rampes sont prévues pour atténuer le pincement des joints d'étanchéité entre les segments quand les segments sont tirés l'un vers l'autre, comprimant les joints d'étanchéité pour former un raccord de tuyaux étanche.
