Abstract:
An insulated high-temperature transport conduit for use in undersea environments. The conduit comprises a continuous steel pipe having at least a first layer of thermal insulation provided over its outer surface. The first layer of thermal insulation comprises a polymer composition having a thermal conductivity of less than about 0.40 W/m K and long-term heat resistance at continuous operating temperatures within the range from about 150°C to above about 205°C. The first thermal insulation layer comprises a polymer composition comprising a polymer selected from the group consisting of one or more fluoropolymers,hydrogenated nitrile butadiene rubber (HNBR), anda blend of one or more fluoropolymers with HNBR. The conduit may further comprise second and third layers of insulation on top of the first layer, along with a corrosion protection coating underlying the first thermal insulation layer.

Abstract:
A thermal insulator includes a plurality of layers. At least some of the layers include phononic crystals having a phononic bandgap, wherein heat transporting phonons within a selected range of frequencies are substantially blocked by each phononic crystal layer. The plurality of layers thermally isolate a first region from a second region, wherein the first region is at one end of the plurality of layers and the second region is at the other end of the plurality of layers.
Abstract:
A tubular thermal sleeve assembly (10) for providing protection to an elongate member (11) and method of enhancing the robustness of a thermal sleeve (14) with the assembly is provided. The thermal sleeve assembly includes a tubular wall (20) of insulative material having an outer surface (15) and an inner surface (16) bounding a cavity extending along a longitudinal central axis (18) for receipt of the elongate member. The assembly further includes a flexible outer layer (22) of metallic material extending along the longitudinal central axis between opposite ends (24, 26) with the metallic material having a plurality of openings (38) formed between the opposite ends.
Abstract:
A storage container that includes walls having complimentary-shaped edges with complex edge profiles. The complex edge profiles of adjoining walls mate with each other to form an interface that defines a thermal leak path between a storage area of the container and an exterior environment. The thermal leak path has a length that is greater than the thickness of the adjoined walls. In one example, the complex edge profile includes step-shaped features. The walls may also include one or more overlapping super-insulating panels. The panels may be joined to one another with adhesive layers. The super-insulating panels may be also be disposed in a wall including interior and exterior linings that are joined and sealed to define a space between the linings. The space may be evacuated and optionally filled with a super-insulating gas.

Abstract:
A composite insulating structure comprises a reflective non-interlocking layer and two or more flexible and curable layers that include a preferably high-performance insulating material to provide substantial flexibility for installation while allowing the structure to be cured to form a fluid impervious and preferably rigid barrier layer. It is further preferred that the reflective non-interlocking layer faces the heat trace and thus avoids entanglement of insulating material with the heat trace while providing a first thermal barrier against heat loss.

Abstract:
Method and apparatus for producing syntactic materials comprising a matrix material having a quantity of microspheres dispersed therein, whereby microspheres of incompressible material may be utilised. Liquid components which react to form the matrix material are mixed in first mixing means (122), and the uncured matrix material is mixed with microspheres in a predetermined ratio in a second mixing means of a type which will not damage the microspheres, such as a rotating pin mixer, a static screw mixer or a static turbulence mixer. The syntactic material so produced is suitable for use in coating pipelines or the like, and for other purposes. Also disclosed is a method of improving the impact resistance of a coated pipe, by incorporating a wrapped strip of glass fibre fabric into the coating material.
