    摘要: An annular dual barrier seal (10) includes a pair of axially extending inner seal lips (20a, 20b) and a pair of axially extending outer seal lips (22a, 22b), the pair of inner seal lips are connected to the pair of outer seal lips by a radially outwardly extending web portion (24). The pair of inner seal lips extend axially by a first dimension and the pair of outer seal lips extend axially by a second dimension which is greater than the first dimension. The pair of inner seal lips have a sealing surface (26) that is one of partially toroidal and partially elliptical and that engage the radially inwardly facing first sealing surface and the pair of outer seal lips have a sealing surface (28) that is one of partially toroidal, partially elliptical and conical.

    摘要: A system for establishment of a sealing connection between two axially impacting members (10, 11) in a pipe conduit, has an intermediate, elastically yielding metal sealing ring (59) arranged in a groove between the members. The sealing ring (59) is made of highly elastic rust-free steel and designed wedge-shaped. By prestressing the sealing ring between the members sealing engagement of the sealing ring is ensured. During use the sealing ring is adapted to be moved radially outwards in the associated groove and thereby compensates for tendencies to the opening of the gap between the members with the occurrence of high medium pressures in the pipe conduit. After cessation of the high pressures the sealing ring is adapted to occupy the starting position again.

    摘要: Le dispositif comprend un premier élément de raccord métallique (3) rendu solidaire d'un premier élément de tuyauterie (T′) et un second élément de raccord métallique (1,2) rendu solidaire d'un second élément de tuyauterie (T). L'un (1,2) des éléments de raccord présente une lèvre élastique (23) coopérant avec une face frontale (32) réalisée sur l'autre élément de raccord (3).
    L'élément (1, 2) présentant une lèvre élastique (23) comprend un élément d'ajutage (1) en un métal ou un alliage métallique compatible du point de vue soudure avec le matériau de l'élément de tuyauterie (T) auquel il est raccordé par soudage (12) et coopérant avec l'écrou de serrage (4), et une pièce d'extrémité (2) présentant en demi-coupe axiale la forme d'un V couché pour définir ladite lèvre élastique (23), ladite pièce d'extrémité (2) étant réalisée en un matériau différent de celui de l'élément d'ajutage (1) pour présenter des caractéristiques mécaniques améliorées conférant l'élasticité nécessaire au raccord, et étant rendue solidaire de l'extrémité libre de l'élément d'ajutage (1) par soudure par diffusion.

    摘要: The present invention concerns a rotatable coupling (60) for connecting pipes, comprising a first hollow female element (61) suited to be connected, for example, to a first pipe portion (51), and a second tubular male element (6) with a first end portion at least partially housed inside the first female element (61) so as to define an inner space for the passage of a fluid, and with a second end portion suited to be connected to a second pipe portion (52). Said first and said second element (61, 6) can be rotated with respect to each other, said second tubular male element (6) comprising a first abutment surface (6S). Furthermore, the rotatable coupling (60) comprises a third hollow tubutar element (12) housed inside the first female element and provided with a second abutment surface (1S) substantially opposite the first abutment surface (6S) so as to define a first interspace (I), and the third tubular hollow element (12) can be translated along a direction substantially orthogonal to the first and the second abutment surface (6S, 1S) between a closed configuration, in which the first and the second abutment surface (6S, 1S) are positioned at a minimal mutual distance, and an open configuration, in which the first and the second abutment surface (6S, 1S) are positioned at a distance that exceeds said minimal mutual distance.

    摘要: A metal seal fitting for use on a pipe or pipeline includes at least one metal seal ring having a C-profile which houses a spring and is arranged concentric to, and outside of, a tap diameter of the access connection. The seal ring is double-curved so that it conforms to a pipe-facing side of the fitting. A surface of the pipe is prepared to receive the seal and, as the fitting is being secured to the pipe, the seal is activated and spring-energized. In its final sealing state, the seal is not compressed passed its deformation point and maintains its spring-back capability. After the fitting is removed from the pipe, the seal may be re-used. The metal seal fitting is suited for applications requiring a high integrity seal and can be used in high pressure, high temperature, and highly corrosive environments which are not well-suited for elastomeric seals.
