A gasket in a transport refrigeration system (TRS) and method of preventing corrosion in a compressor using a gasket. The gasket includes a body, where the body includes a fluid pass portion, and a flange that extends from the body. The body and the flange include a second layer between an outside first layer and a third layer. The second layer is a metal and the metal is a non-uniform thickness that extends across the flange and the body to deflect compression load distribution.

An assembly includes a first tube defining a first smooth, planar surface at an end of the first tube. The assembly includes a second tube defining a second smooth, planar surface at an end of the second tube. The assembly includes a force mechanism configured to apply a force to at least one of the first tube or the second tube to maintain contact between the first surface and the second surface. The first surface and the second surface are configured to interface to form a substantially hermetic seal when the assembly is cycled through a temperature cycle. The force is substantially normal to the first and second surfaces.

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.

A connection system for a cryogenic tank with a tank wall formed with a first material. A connector is provided for a component to be connected to the tank. The connector is formed with a second material, and the connector is positioned on an exterior side of the tank and essentially congruent with a passage opening of the tank wall. At least one sealing element is provided, and the first and the second material have different thermal expansion coefficients. A counterpart formed with the second material is positioned on an interior side of the tank, and is connected with the connector via at least two fastening elements, such that the tank wall is clamped between the counterpart, the connector and the at least one sealing element, and a slight displaceability of the connector and the counterpart parallel to the tank wall remains to compensate for thermally induced mechanical stresses.

A flange fixing structure is provided that fixes flange parts respectively provided to two pipe conduits by means of a fixture in a butting manner via a gasket. In this flange fixing structure, when an effective length of the fixture is denoted by L.sub.0, a linear expansion coefficient of the fixture is denoted by .sub.0, thicknesses of n (where n is an integer of 1 or more) members held by the fixture are respectively denoted by t.sub.1 to t.sub.n, and linear expansion coefficients of the n members are respectively denoted by .sub.1 to .sub.n, a product L.sub.0.sub.0 of the effective length L.sub.0 of the fixture and the linear expansion coefficient .sub.0 of the fixture is substantially equal to a sum t.sub.i.sub.i (i=1 to n) of products of the respective thicknesses t.sub.1 to t.sub.n and the respective linear expansion coefficients .sub.1 to .sub.n.
