Abstract: A vacuum pump comprises an inlet flange for connecting to a vacuum chamber, where the inlet flange comprises a plurality of apertures for receiving a plurality of protruding fixing elements extending from the vacuum chamber. The protruding fixing elements comprise an enlarged retaining portion at an end remote from the vacuum chamber and a fastener receiving portion having at least one radial dimension that is smaller than a corresponding dimension of the enlarged retaining portion. A fastening mechanism is provided that comprises a plurality of slots each extending from a same side of a plurality of apertures. The fastening mechanism is configured to be rotatable between a mounting position in which the apertures are aligned with the protruding fixing elements and a sealing position in which the slots are aligned with the protruding fixing elements.

Abstract: A method for sealing a junction with a contact surface and counter-contact surface of an element of a compartment of a gas-insulated substation includes an injection of a sealing product into an inter-seal volume formed between the contact surface and counter-contact surface by using a leakage recovery duct opening into the inter-seal volume. During injection, the sealing product is in the form of a liquid whose kinematic viscosity, measured at 40° C. under 1 atm, is greater than or equal to 3000 mm2/s. Injection is carried out under pressure by a plurality of successive increases in injection pressure until any residual gas is expelled from the inter-seal volume by pressurized leakage of this residual gas via at least one of the two mechanical seals.

Abstract: A connection assembly between two portions of a line including an inner conduit for transporting a cryogenic fluid, the assembly including two flanges which are respectively arranged at the ends of the line portions and which are configured to be held in contact with one another by virtue of a fixing arrangement. The contact zone between the two flanges includes at least two grooves for positioning seals and at least one conduit opening out, for the one part, between the two seals and, for the other part, into an expansion chamber for the cryogenic fluid. The expansion chamber is arranged in one, or in the vicinity of one, of the first connection flange and the second connection flange. The expansion chamber includes a detector for detecting the presence of the cryogenic fluid in the expansion chamber or a recess configured for the installation of such a detector.

Abstract: A pipe connector includes a connecting structure configured to secure a first section of hose, pipe, or tube to an adjacent second section of hose, pipe, or tube positioned adjacent to the first section at a joint between the first section and the second section. The connecting structure includes at least one segment of a thermally adaptive material. The at least segment is configured to undergo a shape change as a result of thermal cycling such the shape change causes the connecting structure to form a leak-free seal between the first section and the second section at the joint.

Abstract: A polymer-lined fluid transmission line includes various structures, including a first polymer-lined pipe, a second polymer-lined pipe, and one or more sleeve retainers installed at a pipe junction between the polymer-lined pipes. Among other things, the sleeve retainers may include one or more protuberances to frictionally engage the polymer-lined pipes or a one or more portions that protrude into a space between the polymer-lined pipes to help retain and protect polymer sleeves.

Abstract: The techniques introduced here include a system and method for efficiently connecting two or more pipes through the combination of a pushing plate, a gasket and a sealing plate. Such techniques exploit the presence of concentric protuberances, or rings, on the sealing plate that help, also thanks to the space between them, in keeping the cleanness, tightness and flexibility of the conjunction, especially when sticky substances, like a sludge, are dealt with.

Abstract: A sealing device for sealing a space defined between respective end portions of an adjacent pair of orthogonal flange members of a conditioned air duct having a generally rectangular cross-section. The sealing device includes a substantially planar first plate member having a surface configured for placement in face-to-face relation with corresponding adjacent planar surfaces of the adjacent pair of orthogonal flange members. A leg member extends away from a generally central portion of the first plate member and is generally perpendicular thereto. The leg member includes second and third orthogonal plate members extending in respective orthogonal planes and having respectively orthogonal surface portions. The second and third orthogonal plate members are configured and dimensioned to engage corresponding respective adjacent orthogonal inner wall surface portions of the duct when the first plate member is positioned on the planar surface portions of the adjacent pair of orthogonal flange members.
