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.

A pressure vessel apparatus according to exemplary aspects includes: a branched tube comprising a tube main body and three branches, wherein a side branch of the branches comprises a flared out portion connected to the tube main body; a liquid inlet opening disposed at a first branch of the branched tube; a liquid outlet opening disposed at a second branch of the branched tube; a gas inlet opening disposed at a third branch of the branched tube, wherein the third branch is the side branch; and a cover plate configured to mount a valve actuating mechanism in the branched tube, the cover plate configured to be joined to the branched tube at the third branch.

A heat-insulated box for insulating parallel-slide valves includes multiple sections each including an outer protective steel envelope with a heat insulation coating on an inner surface. A number and configuration of sections is determined based on geometric parameters of the insulated valve. Some sections include two semi-cylindrical segments rigidly coupled together and oriented in mutually perpendicular directions such that one segment can be installed on the valve and one segment can be installed on the pipeline. The box also includes stiffeners at the junction of the two semi-cylindrical segments. The sections include shock-absorbing sealing gaskets made of cellular rubber substance to ensure a tight seal of the box. The box includes a locking mechanism for coupling the sections together.

A gas station for delivery of gas to appliances, in particular in a building, comprising a casing (12) and a gas regulation device (13) with several components comprising a gas regulator 14 and one filter (32), wherein the gas regulation device (13) is mounted or mountable within the casing (12), wherein the casing (12) comprises a ground plate (10) and a cover element (11) being securable or secured onto the ground plate (10), wherein the ground plate (10) is configured for mounting to a wall or to an external mounting post (50).

A gas station for delivery of gas to appliances comprising a casing and a gas regulation device comprising at least a gas regulator and a filter. 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 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.
