  • Patent number: 11187367
    Abstract: A passivating flexible insulation blanket positionable about a pipe includes an insulation core, an enclosing fabric, and a non-consumable passivator. The insulation core is substantially hydrophobic and includes a microporous material. The enclosing fabric fully encapsulates the insulation core to form a capsule or pouch about the insulation core. The non-consumable passivator is non-consumable such that there is no appreciable change to a mass of the non-consumable passivator after an extended time of activation. The non-consumable passivator is deposited into the insulation core and has a composition soluble in water. The non-consumable passivator includes a leachable component that leaches from the insulation core and is capable of neutralizing acidic components. The leachable component is water soluble and is capable of reacting with a surface of the pipe to form a protective coating on the pipe to aid in inhibiting corrosion formation on the surface of the pipe.

  • Patent number: 10969028
    Abstract: A shrouded valve assembly includes a valve with a valve pipe and a valve channel. A valve member in the valve channel can regulate flow of fluid through the valve channel. A valve shroud provides a valve shroud chamber. First and second shrouded pipe assemblies are on opposite sides of the valve, each including a pipe in fluid communication with a respective end of the valve channel, and a pipe shroud providing a pipe shroud chamber. Each pipe shroud chamber is in fluid communication with a respective end of the valve shroud chamber. The pipe assemblies are connected to the valve shroud by first and second connections and to the valve by third and fourth connections, the fourth connection more flexible than both the first connection and the second connection. Load passes between the pipe assemblies via the valve shroud rather than via the valve, protecting the valve from damage.

    Abstract: A pipe jacket is disclosed for use with pipes such as hydrocarbon based liquid and gaseous high pressure oil pipelines. The pipe jacket exhibits ballistic self-sealing properties through the use of ballistic fabric surrounding a self-sealing core. The self-sealing core makes use of compressible polymers, which close back on themselves when a foreign object such as a bullet passes through to prevent most leakage, and a self-sealing fluid to fill in whatever space remains. The compressible polymers are kept under a pressure greater than the internal pipeline normal maximum operating pressure by a fastening system which securely fastens one end of the pipe jacket to the other after the pipe jacket is placed around the outside of the pipe. The pipe jacket may also optionally provide additional protection from blasts, electric drill sabotage, corrosion, and thermal variation.

  • Patent number: 6523577
    Abstract: An insulation system for shafts through which hot gases flow, especially exhaust gas shafts of gas turbines has an insulation layer (20, 40) as well as a flat cover (26, 39), which holds the insulation layer (20, 40) and covers it against the gas flow. The cover (26, 39) is guided by bearing rails (21, 41). In such an insulation system, the number of spacers (22, 23, 24; 47, 48, 49) by which the bearing rails (21, 41) are fastened to a shaft wall (25, 50) shall be minimized. Furthermore, the insulation system shall be able to be manufactured with a high degree of prefabrication in the workshop and with low assembly effort at the construction site. The bearing rails (21, 41) are fastened to the shaft wall (25, 50) with a fixed mount (31, 51) and at least one movable mount (32, 52).

  • Patent number: 6465110
    Abstract: A laminate comprises first and second metal layers, and a metallic felt layer disposed between the metal layers and attached to each to provide vibrational damping and thermal insulation. In one embodiment, the layers are tubular in shape and form an automotive exhaust pipe. In another embodiment the layers are annular in shape and form a disk of a brake rotor. In another embodiment the laminate is a damping structure for a brake pad assembly, wherein the first metal layer may either be the backing plate of the brake pad assembly or be attached to the backing plate. The damping structure may include additional metallic felt and metal layers. Various modes of attachment of the metallic felt layer to the metal layers are disclosed. The metallic felt layer may be completely surrounded by metal.

  • Patent number: 6403180
    Abstract: An insulating system for pipes is provided which includes at least two different types of pipe insulation, wherein each pipe insulation is a pipe jacket formed by two mating sections, a first section and a second section with each section having a mating surface, wherein further when the two mating sections are put together with the mating surface of the first section exactly abutting the mating surface of the second section, they form a tubular structure having a bore which is a suitable size to receive a pipe. Of the three possible types of pipe insulation available, insulation A, insulation B, and insulation C, each pipe insulation type is formulated to insulate pipes having a different surface temperature, and yet pipe insulations A, B, and C each have identical outer diameters.

  • Patent number: 5690147
    Abstract: A heat-insulating assembly (10) for insulating a surface of a tubular body (30) relative to the ambient air comprises a length of an annular heat-insulating body (12, 14) defining an inner cylindrical surface (17) and an outer cylindrical surface (16). A vapor-barrier layer is applied to and covers the outer cylindrical surface of the annular heat-insulating body. A through-going slit (11, 15) extends through the annular heat-insulating body (12, 14) in the entire length thereof for allowing the annular heat-insulating body (12-14) to be opened for positioning the annular heat-insulating body (10) circumferentially encircling the tubular body (30) so as to position the inner cylindrical surface (17) juxtaposed the surface of the tubular body (30).

  • Patent number: 5591940
    Abstract: A protective sleeve includes a sleeve body and a cover, each having a generally semi-cylindrical cross-section. The cover includes a groove along its longitudinal edges for receiving a silicone chord sealing gasket. The sleeve body has a short cylindrical externally threaded section at one end for threaded connection within the recess of a connector ring. One end of the cover is disposed in the recess and the opposite end engages a stop carried by the sleeve body. The cover and sleeve body are latched with over-center latches to one another whereby an effective seal is formed between the cover and sleeve body. By opening or closing the latches and manipulating the cover relative to the sleeve body, the cover can be replaced rapidly should the sealing gasket become damaged.

  • Patent number: 5538045
    Abstract: A braided product and process include a first sleeve formed of interbraided first and second yarns which may be continuous E glass yarns. Warp beads formed by knitting or braiding are equidistantly spaced around the circumference of the braid and introduced to the braider to form an integral part of the structure. One or more heavy denier yarns are loaded on carriers so as to cross the warp beads under relatively high tension, forcing the beads selectively to the inside or outside of the sleeve surface so as to create longitudinally extending spacers which create air gaps between the sleeve and the surface of the substrate being covered.
