A cover for HVAC conduits and wiring exiting a structure is provided permitting a simplified solution to protect the line set in an aesthetically pleasing manner. A two-part face plate fits around the conduits and wiring. Each face plate includes a partial cone-shaped protruding member that circumscribes the conduits and wiring once installed. The cover also includes a sleeve that fits around the conduits, distal the cone-shaped protruding members in a tight-fitting manner providing further protection. The cover is easily removeable for a service technician to maintain and repair the conduits or wiring in future servicing.

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.

An insulating cover for assemblies including pipe elements, pipe couplings, elbows, Tees and valves also acts as a vapor barrier. Cover portions are joined along a seam which provides for a continuous seal between both the cover portions and the pipe elements which extend through channels defined in the cover. The seam includes a furrow into which sealant is forced when the cover portions are joined around the assembly. The furrow is defined by an asymmetric tongue and groove joint. Canals in the channels, in communication with the grooves, also receive the sealant to provide the continuous seal.

An insulating jacket for enclosing a pipe fitting includes an elbow housing configured to envelop and cover a pipe elbow and a pair of coupling housings each configured to envelop couplings mounted to the elbow. Each of the housings is made from a pair of housing halves which are made from a block of rigid insulating material. Each pair of housing halves can be mated together by interlocking tongue in groove connection elements formed on the housing halves. The rigid insulating material is soft enough to be carved by hand and resilient enough to be deform sufficiently to allow the housing halves to be mated over the pipe fitting.

Regasification systems and processes for converting liquid natural gas (LNG) from a liquid into a gaseous state are described. The process includes a closed-loop system that uses geothermal wells as a heat source. A warming fluid circulates through the closed-loop system coupled with a geothermal well and a LNG heat exchanger. The warming fluid is heated as it passes through the geothermal well and cooled as it passes through the LNG heat exchanger, thus heating and gasifying the LNG. The cooled warming fluid then returns to the geothermal well. The closed-loop system minimizing environmental impact by eliminating the need to discharge the warming fluid.

An exhaust elbow includes an inlet, an outlet, a curved gas guiding duct between the inlet and the outlet, and a plurality of thermally insulated stiffeners connected to an external surface of the curved gas guiding duct, each of the stiffeners including a metallic component and thermal insulation adjacent to at least a portion of a surface of the metallic element.

The present disclosure provides insulated components that include corrugated regions, which corrugated regions may reside on inner tubes, outer tubes, or both. The present disclosure also provides insulated components that may achieve straight, curved, or other variable geometries.

For manufacturing composite parts (1) having an inner hollow moulded body (2) with openings (3), which are accessible from outside, the moulded body is introduced into a moulding tool on the mould walls on which a shell layer (11) was applied. The hollow space between the moulded body (2) and the shell layer (11) is filled with a thermally insulating plastic foam (12) which is foamed in the moulding tool and bonds to the moulded body and the shell layer. After removal, a moulded body is provided, which has a qualitatively good surface formed by the shell layer. Such a composite part is preferably used for connecting thermally insulating pipes.
