A union for connecting two tubular members. The first tubular member has an external flange, and the second tubular member has a set of external threads. An annular nut surrounds the first tubular member. The nut has an internal flange that surrounds the first tubular member, and a set of threads to engage the threads of the second tubular member. Arcuate segments are circumferentially mated between the internal flange of the nut and the external flange of the first tubular member. A flat conical surface on the inner side of the segment comes into contact with a flat conical surface on the outer side of the external flange. Curved conical surfaces tangentially align with and extend from the flat conical surfaces on the segment and the external flange. Cylindrical surfaces tangentially align and join the curved conical surfaces on the segment and the tubular member.

Un raccord-union permettant le raccord de deux éléments tubulaires. Le premier élément tubulaire comprend une bride externe et le deuxième élément tubulaire comprend une série de filets externes. Un écrou annulaire entoure le premier élément tubulaire. L'écrou est muni d'une bride interne qui entoure le premier élément tubulaire, et une série de filets qui engagent les filets du deuxième élément tubulaire. Des segments en forme d'arc sont accouplés de manière circonférentielle entre la bride interne de l'écrou et la bride externe du premier élément tubulaire. Une surface conique plane sur le côté intérieur du segment entre en contact avec une surface conique plane sur le côté extérieur de la bride externe. Des surfaces coniques courbées s'alignent de manière tangentielle sur les surfaces coniques planes et se prolongent sur le segment et la bride externe .Des surfaces cylindriques s'alignent de manière tangentielle sur les surfaces coniques courbées et les joignent sur le segment et l'élément tubulaire.
