  • Publication number: 20150090360
    Abstract: An insulated duct includes an inflatable jacket surround the duct. The jacket is inflated, preferably with air traveling in the duct, to create a static condition in the air space formed by the jacket to provide additional insulation for the duct. When the jacket is combined with additional insulation and low emissivity material, the R value of the duct can be increased in a more efficient manner from manufacturing and cost viewpoints.

  • Patent number: 8973619
    Abstract: A climate tube, in particular for aircraft, includes an inner layer and an outer layer of fiber composite plastic material. To achieve a high stiffness combined with a low weight and to achieve good thermal insulation properties, disposed between the inner layer and the outer layer is an at least almost completely circumferential honeycomb core, which is firmly connected to the inner layer the outer layer. The radial extent of the honeycomb core is large compared to the radial extent of the inner layer and the outer layer, and the mutually opposed longitudinal ends of the honeycomb core abut one another and are surrounded by a ply of fiber composite plastic material.

  • Publication number: 20150041018
    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/mK 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), and a 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.

  • Patent number: 8950439
    Abstract: An intermediate insulating product (20) is disclosed comprising a planar insulating layer (11) having a top side in to which is formed a plurality of parallel channels (14) having cross-sections with tapered sides. A vapor proof layer (18) is applied to the top surface after the channels (14) have been formed such that the vapor proof layer (18) bridges the plurality of parallel channels (14). The intermediate insulating product (20) is then bent with mechanical manipulation in regions adjacent the bottom of the channels (14) thereby causing the channels (14) to close to form a non-planar, derivative insulated ductwork product (30) and the vapor proof layer (18) forms a vapor proof inner lining to the derivative insulated ductwork product (30).

  • Patent number: 8950071
    Abstract: During the manufacturing of heat-insulated pipes (1) with an inner duct (3) and an outer duct (2) and a foamed insulation (14) arranged in between, the inner duct is placed on a tension member (10). The latter is tensioned between tensioning means by means of a tensile force, such that it runs straight and that the inner duct is held straight. The latter is held on centering elements (16, 17) which are spaced from one another in a defined way by means of spacers (18). In this straight position the inner duct may be surrounded with foam inside of the outer duct, without needing spacers between the ducts.

  • Publication number: 20140373954
    Abstract: An insulation system for process vessels or piping. In one embodiment, a first sheath having a heat-reflective coating on an inner surface thereof is spaced from a structure. A second outer sheath is provided exterior to the first sheath. An insulation layer is provided intermediate the sheaths. In another embodiment, an outer sheath has insulation disposed on an inner surface thereof, the insulation being intermediate the inner surface and the structure and is spaced therefrom. A liner having a heat-reflective coating on an inner surface thereof is provided on the inner surface of the insulation. In another embodiment, a reflective metal foil is wrapped around a structure which may be equipped with an external heating means. A shell having an inner heat-reflective surface is disposed circumferentially to the structure, with an air gap there between. Disposed exterior to the shell is insulation, and optionally, a protective coating and/or second shell.

  • Patent number: 8863784
    Abstract: A system, in certain embodiments, includes a multi-layer composite strip of pipe dampening materials, comprising a first layer of a first material, a second layer of a second material disposed adjacent to the first layer of material, and a third layer of a third material disposed adjacent to the second layer of material, wherein the second material comprises a viscoelastic material, and wherein the multi-layer composite strip of pipe dampening materials is configured to be affixed to an outer surface of a section of pipe. In certain embodiments, the first layer and the third layer may have stiffness values that are substantially different from each other. The difference in stiffness values may enable relative motion in the first layer and the third layer to be generated during vibration of the section of pipe, and the energy may be dissipated by the viscoelastic material, thereby dampening vibration of the section of pipe. In certain embodiments, multiple strips of pipe dampening materials may be used.
