A duct joint assembly between a first section and a second section, each section consisting of an inner tube and an outer tube, the outer tube surrounding the inner tube, and between which a heat insulator is placed. Each section has a fastening body so that the sections can be assembled to, or disassembled from, each other.

Presently disclosed self-regulating thermal insulation may include one or more thermal actuators that may expand and contract in response to changes in temperature adjacent the thermal insulation, thereby automatically changing the thermal resistance of the thermal insulation. In this manner, a self-regulating thermal insulation may be configured to locally adjust in response to local changes in temperature of a part being insulated, for example, during curing or some other manufacturing process. Such self-regulating thermal insulation may be configured to respond to temperature changes without feedback control systems, power, or human intervention. One example of self-regulating thermal insulation may include a first plate, a second plate, a support structure coupling the first plate and the second plate and defining an insulation thickness therebetween, an internal partition positioned between the first plate and the second plate, and at least one thermal actuator positioned between the second plate and the internal partition.

A flexible joint assembly is disclosed for use in an extreme temperature fluid flow system. In an embodiment, the flexible joint assembly can be used in a fluid flow system configured to carry high temperature fluid, such air or other gas, and/or in a fluid flow system configured to carry low temperature fluid, such air or other gas.

An insulating shell designed to fit a variety of thermal expansion tanks which provides substantial insulation. The insulation shell includes a first half shell, a second half shell, and an interlocking mechanism. The first half shell and the second half shell join together to form an enclosed shell with a hollow interior. The first half shell and the second half shell each include a main body, a central cavity, and a hole. The main body provides the thermal insulation. The central cavity laterally traverses into the main body through a planar mating surface and receives the tank. The hole traverses into the main body from an external surface to an internal surface and received associated plumbing of the tank. The interlocking mechanism includes a first engaging element and a second engaging element, which are used to attach the first half shell and the second half shell together.

The disclosure relates to a saddle support for use in above-ground pipeline construction in severe geological conditions, such as permafrost. The support provides structural stability and redistribution of a load from a pipeline to a pile foundation. The saddle support includes the spool coupled to four adjustable stands through electric insulating units. The stands can be adjusted to change a height and slope angle of the support and are fastened to a single-level pilework that supported by the pile foundation via flanges. The spool is a pipe having an external case and a heat-insulating layer. Longitudinal ribs are fastened to the spool to fasten the spool to the stands. The load-bearing structure of the spool resists axial and side movements of the pipeline and transfer the load absorbed by the spool to the pilework foundation via the electric insulating units on the adjustable stands.

A device for transferring fluid between two separate structures includes a rigid pipe with a double shell extending along a longitudinal axis. The pipe includes an outer-shell housing (in the inner vacuum space thereof), at least one inner duct for fluid transfer, and at first and second ends thereof, includes respective first and second rigid connections of the outer shell to the first structure and second structures, respectively. The first and second ends of the outer shell are rigidly connected to the at least one inner duct. The pipe comprises a system to compensate for movements in the longitudinal direction.
