A pipe for conducting a cryogenic fluid. The pipe includes a rigid outer tube at least partially made of a fiber-reinforced polymer, a gas-proof inner tube running within the outer tube, an insulation layer arranged between the inner tube and the outer tube, and at least one flange formed at a respective end of the inner tube. The at least one flange connects the inner tube with the outer tube. Also a pipe assembly with at least two such pipes which are connected or configured to be connected at their respective flanges, and an aerospace system with at least one such pipe.

The invention relates to a method of fabricating an insulation element (2) as an insulation box, cap or cover for a valve, a flange or a fitting insulation within a piping system of a technical building equipment. Said method comprising the steps of forming a block of insulating material to be provided with a cavity having a contour of the valve, the flange or the fitting insulation and an outer contour, whereby the block is divided into at least two parts, preferably two halves (3) of the insulation box, cap or cover, and forming a complementary insulating covering (6) having an inner contour according to the outer contour of the block. To provide a method of fabricating the insulation element (2) having increased properties in view of combustibility and being cost saving because of an easy and less complex method for manufacturing insulation elements (2) which can be used at least for a range of valves, flanges or fitting insulations within a piping system of a technical building equipment having different sizes and/or outer contours the insulation element (2) and the complementary insulating covering (6) are produced separately from each other and joined together, whereby the block is produced from mineral wool, i.e. mineral fibers bound with a binding agent, and the complementary insulating covering (6) is produced from a plastically deformable material being mechanically pressed or molded to be provided with the inner contour corresponding to the outer contour of the block provided with the cavity.

Heat resistant systems provide a self-activating insulative solution. A seal system includes a case defining a joining line where two sections of the case join together. The case envelops an internal space and separates the internal space from an external space. A seal is disposed at the joining line and a case extension defines a cavity on an outside of the seal. The case extension has an opening that extends between the cavity and the external space. A lining of a heat responsive material is provided in the case extension. The material expands to an activated state when exposed to heat above a threshold temperature and passes through the opening encapsulating the case extension and insulating the seal from the external space.

A vacuum-insulated pipe assembly including an outer pipe and an inner pipe within the outer pipe, the inner and outer pipes concentric along a common central axis, the outer pipe spaced from the inner pipe to define a space, the space evacuated to define a vacuum. The outer pipe includes first and second outer pipe sections, the first outer pipe section includes a first outer connector, and the second outer pipe section includes a second outer connector, the first outer connector removably connected to the second outer connector at an outer connection interface. The inner pipe includes first and second inner pipe sections, the first inner pipe section includes a first inner connector, and the second inner pipe section includes a second inner connector, the first inner connector removably connected to the second inner connector at an inner connection interface.

A vacuum insulated pipe assembly including a first pipe section and a second pipe section. The first pipe section has a first outer wall and a first inner wall within the first outer wall. The first outer and inner walls are concentric along a common central axis, and the first outer wall is spaced from the first inner wall to define a first space. The second pipe section has a second outer wall and a second inner wall within the second outer wall. The second outer and inner walls are concentric along the common central axis, and the second outer wall is spaced from the second inner wall to define a second space. The first inner wall includes a first inner connector and the second inner wall includes a second inner connector connected to the first inner connector.
