An vacuum adiabatic body includes a first plate, a second plate, and a support configured to maintain a vacuum space between the first and second plates. The support includes a support plate supported on an inner surface of one of the first plate and the second plate and a bar extending from the support plate. The bar contacts an inner surface of the other of the first plate and the second plate. The one end of the bar has a cross-section less than that of the other end of the bar.

A device for connection of double-wall pipes including an interior connection system connecting the first and second interior pipes and an exterior connection system including a first part that cooperates with an end section of the first exterior pipe and a second part that cooperates with an end section of the second exterior pipe. The exterior connection system is configured so that at a first temperature at least one of the first and second parts exerts a contact force on the end section of the corresponding first or second exterior pipe greater than at a second temperature higher than the first temperature in order to reinforce the seal, especially in the event of a hydrogen leak when hydrogen is present in the first and second interior pipes.

A transition section (10) disposed between successively-spoolable electrically trace-heated PiP pipelines (12) comprises an inner pipe, an outer pipe and an annulus between the inner and outer pipes. The annulus contains heating cables (26) that extend longitudinally between annuli of the pipelines and longitudinally-spaced seals (44) that, when deactivated, allow fluid communication between the annuli of the pipelines and, when activated, isolate the annuli of the pipelines from each other. Longitudinally-spaced blocking plates (32) close the lumen of the inner pipe and define an inner chamber between them. Longitudinally-spaced openings (40) penetrate a wall of the inner pipe at locations longitudinally inboard of the blocking plates and the seals. The openings effect fluid communication between the annulus and the inner chamber and also define a diversion path for the heating cables that extends from the annulus to the inner chamber and back to the annulus

A vacuum insulated structure including a first cover member of a stamped unitary sheet defining a perimeter portion positioned at a first planar level and first rib formed in the unitary sheet extending to a second planar level spaced axially outward and disposed radially inward of the perimeter portion, a second cover member, and thermal bridge interconnecting the first cover member and the second cover member at the perimeter portions thereof to define an insulating cavity therebetween. The insulating cavity is a sealed cavity having a vacuum drawn therefrom, and the first rib defines a first portion of a path for air flow out of the sealed cavity during a vacuum draw process.

A main body of a refrigerating includes a plurality of vacuum insulation panels, each vacuum insulation panel of the plurality of vacuum insulation panels including an exterior material having first and second surfaces opposite to each other, and a core material in a vacuum state between the first and second surfaces of the exterior material. The plurality of vacuum insulation panels are assembled together so that the first surfaces of the exterior materials of the plurality of vacuum insulation panels form a storage compartment inside the main body.

A coupling for vacuum-insulated piping is disclosed having first and second parts for forming the coupling; each of the first and second parts comprising an inner portion for fluid communication with an inner part of a vacuum-insulated pipe and an outer portion for fluid communication with an outer, low pressure part of a vacuum-insulated pipe; the inner portions of the first and second parts form an inner region for the passage of fluid therethrough; each of the first and second parts comprising an interface portion for forming an interface with interface portion of the other of the first and second parts, the interface portion comprising a flange for connecting the first and second parts; each of the first and second parts comprises a sleeve surrounding the outer portion, the sleeve comprising a thermally-conducting portion that is in thermal communication with the interface portion so as to conduct heat away from the interface portion.
