    摘要： Ventilation duct connector piece for connection with ventilation ducts or connector pieces, formed by two complementing parts (10a, 10) providing a flow space (4) and having at least two open ends (12), each part (10a, 10b) comprising a fibre layer (2) and an inner layer (3), wherein - the fibre layer (2) comprises mineral fibres and a binder, compressed into a desired shape, the fibres having a melting point over 800 degrees Celsius, - the inner layer (3) is a stainless-steel foil having a thickness of 0,01-0,3 mm, facing the flow space (4). A method of manufacturing the connector piece wherein the steel foil is pressed into two complementing parts, joined along its edges; a binder solution is sprayed on a fibre layer and compressed into two complementing parts under heated conditions, so water evapo- rates, whereafter two fibre parts are positioned on the two steel foil parts.

    摘要： A system to convey a fluid, in particular a fluid containing hydrocarbons, has a first pipeline (2), which is made of an electrically conductive material and has an internal diameter (D1); a second pipeline (3), which is made of an electrically conductive material, has an external diameter (D2) smaller than the internal diameter (Dl), and is placed inside the first pipeline (2) at a distance from the first pipeline (2) so as to form an annular gap (4) between the first and second pipeline (2, 3); an electrically conductive layer (5) placed in the annular gap (4) at a distance from the first pipeline (2); an electrically insulating layer (6) placed between the second pipeline (3) and the electrically conductive layer (5); and a power source (7) to apply an electrical potential difference between the second pipeline (3) and the electrically conductive layer (5).

    摘要： A polyarylene sulfide (PAS) foam layer that circumscribes a hollow inner tube and may have a 50% or greater density reduction relative to the density of an un-foamed PAS polymer material and/or a 50% or greater thermal conductivity reduction relative to the thermal conductivity of an un-foamed PAS polymer material and/or 50% or greater thermal effusivity reduction relative to the thermal effusivity of an un-foamed PAS polymer material. The PAS foam layer may have a low density (e.g., less than 0.67 g/cc) and/or a low thermal conductivity (e.g., anywhere from 0.017 W/(m-K) to 0.145 W/(m-K)) and/or a low thermal effusivity (e.g., less than 316 Ws 1/2 /m 2 /K, optionally anywhere from 38 Ws 1/2 /m 2 /K to 316 Ws 1/2 /m 2 /K) even at high temperatures (e.g., above 400 degrees Fahrenheit (°F) (about 204 degrees Celsius (°C)). Such a PAS foam layer may have characteristics appropriate for use as part of a steam hose.

    摘要： A modular, aerogel-based vacuum insulated pipe section (10) comprising an outer conduit (12); an inner conduit (22) concentrically disposed within the outer conduit (12) with aerogel insulation (30) and a condensable gas being disposed in the insulation space (20) between the concentric conduits (12, 22). As a stand-alone pipe section (10), the insulation space (20) is at a pressure within the range of from about 100 microns Hg to about 1000 microns Hg. However, in operation, when a cryogenic fluid is traversing the inner conduit (22), the condensable gas condenses and the pressure within the insulation space (20) is further reduced to range of from about 1 microns Hg to about 5 microns Hg. The vacuum insulated pipe section (10) further includes a coupling arrangement disposed on a first end (52) of the inner conduit (22) and a second end (54) of the inner conduit (22), the coupling arrangement configured to engage or mate with a corresponding end of another modular vacuum insulated pipe section.

    摘要： 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.
