A three-dimensional multi-shell insulation configured to conform to the shape of a spacecraft component to be insulated. The insulation may have a plurality of nested shell layers that are displaceable relative to each other for providing natural separation between the shell layers when the insulation is used in low-pressure and/or low-gravity space-related applications. To establish the spacing between shell layers, an edge clamp may be operatively coupled to an edge portion on at least one side of each shell layer. The shell layers may have sufficient flexibility and/or may be sufficiently displaceable relative to each other to allow the insulation to be installed or removed from the spacecraft component. One or more restraints may be provided in the space between the shell layers for restricting the relative lateral and/or transverse movement between shell layers for preventing contact. Additive manufacturing may be employed to fabricate the insulation and integrate features.

A heat insulating structure for an exhaust junction pipe to be disposed in an area in which exhaust gas passages having different respective lengths are merged together comprises a first heat insulation portion that covers and provides heat insulation for at least a portion of one branch part of branch parts that are branched in the exhaust junction pipe; the one branch part forms one exhaust gas passage in a not-yet-merged state of the exhaust gas passages, and forms the one exhaust gas passage having a short length.

An insulating cover for assemblies including pipe elements, pipe couplings, elbows, Tees and valves also acts as a vapor barrier. Cover portions are joined along a seam which provides for a continuous seal between both the cover portions and the pipe elements which extend through channels defined in the cover. The seam includes a furrow into which sealant is forced when the cover portions are joined around the assembly. The furrow is defined by an asymmetric tongue and groove joint. Canals in the channels, in communication with the grooves, also receive the sealant to provide the continuous seal.

The gas regulation device is mounted within the casing which comprises a ground plate and a cover element secured onto the ground plate. The ground plate is configured for mounting to a wall or an external mounting post and comprises at least one spacer, so that the ground plate is attached to the wall or the external mounting post in such a way that a predefined gap is maintained between the ground plate and the wall or between the ground plate and the mounting post. The ground plate includes a flap which supports the gas regulation device and the cover element and a hook configured to hook the cover element in the ground plate via a locking element.

A pressure regulator for fluids is described. The pressure regulator (100) has a main body (108) including a control valve (112,113) actuated by a control element (119) responding to a pressure signal generated by sensor means (118) to maintain a set pressure in the transfer line. The main body (108), the control valve (112,113), the control element (119) and the sensor means (118) are contained in an interior space (124) enclosed by a housing (123). A pressure below atmospheric pressure prevails in the interior space (124).

An insulation sleeve for insulating a component includes an inner layer, an outer layer, an insulating material, and a flap covering a seam passing from an outside surface to an internal surface of the insulation sleeve. The inner layer is a material having low thermal conductivity, resistance to high temperatures, is elastic/semi-rigid, and has an inner surface formed to a shape to fit the component. The outer layer has a material having low thermal conductivity, resistance to high temperatures, and is elastic/semi-rigid. The insulating material is positioned between the inner layer and the outer layer and has low thermal conductivity, low heat storage, and resistance to high temperatures. The flap is a material having low thermal conductivity and resistance to high temperatures, and is secured to the outer layer at a first location and releasably secured outer layer at a second location.

The present invention relates to a process to reduce internal stresses in insulation molded onto complex pipes, preferably complex subsea pipe, to reduce cracking in the molded insulation. Insulation materials applies to complex pipes comprising branches, i.e., valves, and the like, may be susceptible to cracking at, or near where the branch connects to the pipe as the coating of insulation material cures or hardens. The process of the present invention aims to reduce post molded cracking by reducing molded in stress at the branch/pipe junction. This is accomplished by providing a preform at or near a branch/pipe junction prior to applying the coating of insulation material.

The thermal insulation system of the present invention is for non-vacuum applications and is specifically tailored to the ambient pressure environment with any level of humidity or moisture. The thermal insulation system includes a multilayered composite including i) at least one thermal insulation layer and at least one compressible barrier layer provided as alternating, successive layers, and ii) at least one reflective film provided on at least one surface of the thermal insulation layer and/or said compressible barrier layer. The different layers and materials and their combinations are designed to provide low effective thermal conductivity for the system by managing all modes of heat transfer. The thermal insulation system includes an optional outer casing surrounding the multilayered composite. The thermal insulation system is particularly suited for use in any sub-ambient temperature environment where moisture or its adverse effects are a concern. The thermal insulation system provides physical resilience against damaging mechanical effects including compression, flexure, impact, vibration, and thermal expansion/contraction.
