The multi-layered conduit is an insulating structure. The multi-layer conduit system forms a thermally protected space that prevents a fluid from changing phase while flowing through the multi-layered conduit. The multi-layered conduit comprises a master pipe, a plurality of coaxial prism structures, a plurality of spoke structures, and a plurality of insulating spaces. The plurality of spoke structures interconnect each of the plurality of coaxial prism structures. The master pipe is a pipe inserts through the plurality of coaxial prism structures such that the combination of the master pipe structure and the plurality of coaxial prism structures form a coaxially oriented composite prism structure. The plurality of spoke structures further forms the plurality of insulating spaces. Each of the plurality of insulating spaces is a gas-filled space that inhibits the transfer of heat through the plurality of coaxial prism structures into the master pipe.

Provided are a composite type heat insulator having an excellent heat insulating properties at high temperatures regardless of its thin body, and a method for producing the same. The composite type heat insulator comprises a first and a second cloths composed of silica fibers having a hydroxyl group; and a heat insulating layer sandwiched between the first and the second cloths. The heat insulating layer contains a silica aerogel and silica staple fibers having a fiber length of 0.5 to 5 mm. The heat insulating layer may optionally contain an infrared absorber and/or a film-forming inorganic binder.

An insulating insert is positioned around a field joint of a pipeline to insulate the field joint. The insert comprises a longitudinal series of annular or part-annular filler segments of insulating material, curved about a longitudinal axis, that are each joined to one or more adjacent segments of the series by at least one link. The links may be webs, rods or articulated links. The links are flexible relative to the segments to facilitate bending of the insert along its length by enabling relative angular displacement between adjacent segments of the series.

A method for forming a super-insulating material for a vacuum insulated structure for an appliance includes disposing hollow glass spheres within a rotating drum, wherein a plurality of interstitial spaces are defined between the hollow glass spheres. An anchor material is disposed within the rotating drum. The hollow glass spheres and the anchor material are rotated within the rotating drum, wherein the anchor material is mixed with the hollow glass spheres to partially occupy the interstitial spaces. A silica-based material is disposed within the rotating drum. The silica-based material is mixed with the anchor material and the hollow glass spheres to define a super-insulating material, wherein the silica-based material attaches to the anchor material and is entrapped within the interstitial spaces. The silica-based material and the anchor material occupy substantially all of an interstitial volume defined by the interstitial spaces.

An aerosol generation device includes a cover element with a heat dissipation material. Further, an aerosol generation device includes: a heating unit for heating an aerosol generation substrate for generating an aerosol; and a device housing which forms at least a part of the exterior surface of the aerosol generation device; wherein the device housing includes an aerogel material configured to insulate the heating unit and/or dissipate heat generated by the heating unit.

An improved acoustic and thermal insulation batting for use, for example, between airframe ribs in aircrafts, and that is stable, lightweight, air permeable to mitigate corrosion issues as well as inherently fire resistant and sized and shaped such that there is no need for positive retention mechanisms owing to the nature of the batting which allows for a compression or friction fit in place. The batting comprises a foam insulation core over which is provided one or more barrier, facing and/or edge layers.

A shielded pipe contains a pipe from chlorinated polyvinyl chloride (cPVC) and a collar which shields the pipe from the environment. The collar contains a bandage which is wrapped around the cPVC pipe, where the bandage contains a carrier layer and a functional layer. The shielded pipe can be used in a corresponding a wall duct. The bandage is useful for shielding a pipe.

Methods of and systems for forming pipe insulation are disclosed. The pipe insulation has properties that are non-homogenous through its thickness.

Provided is an insulation product, optionally in a tubular form, that includes a coated foam insulation layer, where the foam insulation layer has a closed-cell structure. The coating can comprise a thermoplastic elastomer that seamlessly covers and is bonded to an outer surface of the elastomeric foam layer in the absence of an adhesive bonding material to protect the foam insulation layer, e.g., during outdoor insulation applications. A pipe where the insulation product is installed is also provided, as is a method of installing the insulation product, and a method of producing the insulation product.

Disclosed is a material with directional thermal conduction and thermal insulation and a preparation method thereof. The method includes: (1) dispersing a viscose-based carbon fiber in water and adding a phenolic resin and polyacrylamide sequentially to obtain a dispersion I; dispersing a high-thermal conduction carbon fiber in water and adding a phenolic resin and polyacrylamide sequentially to obtain a dispersion II; (2) dividing equally the dispersion I and the dispersion II into several parts, respectively, pouring each part of the dispersion I and each part of the dispersion II into a mold alternately until all the dispersion I and the dispersion II are poured, draining after each pouring of a part of the dispersion I or a part of the dispersion II to obtain a porous carbon fiber skeleton, and solidifying the skeleton to obtain a preform; (3) subjecting the preform to a heat treatment to obtain the material.
