The invention relates to a channel element for a ventilation system. The channel element has a first opening (O1), a second opening (O2), and a channel wall which extends between the openings and surrounds a channel section. The channel element has a tubular section (25) and a thermally insulating envelope section (20) which is paired with the tubular section and envelopes same at least in sub-regions. The invention further relates to a channel element system made of individual channel elements which are connected together in series and a building envelope which contains such a channel element system.

This invention presents a wall mounted receiver to accommodate insulated or non-insulated pipes and at least one inlet or portal for at least one pipe conduit or wiring per portal and with a high degree of flexibility and unique mechanical connection security; this receiver is arranged to receive the piping from any directional angle with a unique flexible inlet capability; without limitation, this receiver is for use with refrigeration or air conditioning equipment and related connections, such as insulated pipes, non-insulated pipes, condensation piping, conduit and wiring. The receiver can be mounted to different wall surface types without the assistance of a wall bracket; can also be fit into tight space service areas depending on refrigeration equipment requirements; can be installed in new construction applications; and can also upgrade existing installations without the need to cut the existing piping.

A fitting structure is provided for supply of gas and connectable between an air supply tube in the form of a hose or a plastic pipe and an air outlet of an air compressor and includes a fitting and a thermal insulation tube. The fitting includes a first coupling opening connectable with the air outlet of the air compressor and a second coupling opening connectable with the air supply tube. The thermal insulation tube has a first end part fixed inside the second coupling opening of the fitting and a second end part extending outside the second coupling opening such that a portion of the thermal insulation tube that extends outside the second coupling opening is received in the interior of the air supply tube. High-temperature air from the air compressor is conducted through the thermal insulation tube into the air supply tube without being directly applied to the fitting.

A connection assembly between two portions of a supply line for a cryogenic fluid, the assembly including a male nozzle arranged to be at least partially inserted into a female nozzle together forming a tight mechanical link, over a distance of a few centimeters, a thermal insulation chamber for each of the two line portions and an additional thermal insulation chamber to thermally insulate the connection zone of the two line portions, and an expansion chamber for the cryogenic fluid that is configured to be linked to a cryogenic fluid sensor, arranged about the connection zone of the two line portions. This enables two cryogenic fluid line portions to be connected without requiring one portion to be inserted into the other portion over a significant length, thereby enhancing mechanical flexibility and obviating the need for significant free space about the connection assembly to assemble and disassemble the assembly.

A vertical connection system for subsea connection of a first tubular member to a second tubular member, the system comprising a lower coupling member comprising an upright casing which encloses a liquid-filled space, wherein a hub of the first tubular member is fixed to the casing at an upper end thereof and the first tubular member extends through said space; and an upper coupling member, which comprises a guide frame configured to slidingly receive said casing when the upper coupling member is lowered downwards onto the lower coupling member, wherein a hub of the second tubular member is fixed to the upper coupling member. The guide frame is provided with a layer of thermally insulating material on its outside. The liquid-filled space is delimited downwards by a bottom wall formed by thermally insulating material or covered by a layer of thermally insulating material.

A thermally insulated transfer line for a deep-cooled fluid. The thermally insulated transfer line includes a process line for conduction of the fluid; an insulation envelope lying radially outside the process line and extending in a longitudinal direction of the process line; an insulation space arranged between the process line and the insulation envelope; and a coupling element provided at both ends of the thermally insulated transfer line, to connect the transfer line to a cryogenic tank, the coupling element being operable to attach the process line to a tank process line of the cryogenic tank and thereby establish a fluid-conductive connection between the process line and the tank process line. The coupling element includes an end piece, wherein the insulation envelope transforms into the end piece, and a connecting sleeve arranged concentric to and radially on an outside of the end piece so as to be attached to the end piece. The thermally insulated transfer line also includes a sliding coupling sleeve operable to connect the connecting sleeve to the cryogenic tank.

A heatshield for a band clamp, the heatshield comprising: an attachment member configured to be inserted axially into the clamp; and a thermal insulator secured to the attachment member, the thermal insulator being configured to at least partially extend over an outer surface of the clamp when the attachment member is inserted into the clamp.
