An expansion joint for a solids return system includes a female joint portion, a male joint portion received by the female joint portion, the male joint portion and the female joint portion forming a lateral breach therebetween, a double rope seal positioned within the lateral breach, the double rope seal being configured to accommodate relative lateral movement between the female joint portion and the male joint portion, and an insulating pillow received about the male joint portion and abutting a distal end surface of the female joint portion, the insulating pillow being configured to accommodate relative axial movement between the female joint portion and the male joint portion.

An arrangement for use in adjoining a support structure to a pipe that passes through the support structure. The arrangement comprises a mount attachable to the support structure. Radial bellows are connected to the mount. The bellows are arranged in use to extend circumferentially around a pipe and be connectable thereto such that a volume is defined by the bellows, mount and pipe.

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.

A heat insulation pipe includes an inner pipe and an outer pipe. The inner pipe includes a pair of inner pipe members spaced apart from each other in an axial direction of the inner pipe, a first bellows disposed between the pair of inner pipe members, and a restriction mechanism for restricting expansion and contraction of the inner pipe in the axial direction to a predetermined range. The restriction mechanism is slidable with respect to at least one of a pair of bulging portions. The outer pipe includes a pair of outer pipe members each including a second bellows, and a second cylindrical portion housing the first bellows and the restriction mechanism.

The disclosure relates to the construction of a support for above-ground pipelines and can be used for laying pipelines in in permafrost and on slopes. The result of the support is uniform distribution of the load from the pipeline to a bedding cradle, displacement of a movable part in response to predetermined conditions, and prevention of deformation due to soil heaving. The result is achieved due to inclusion of moving and fixed parts. The movable part includes a semi-cylindrical cradle with two semi-annular frames on the outside of the cradle, detachable half-yokes fix the pipe in the cradle, side cheeks welded to the frame and movably fixed to the tower base by a hinged joint, and a base slidably positioned on a stationary surface of the support. The objective is also solved using a support assembly being structurally different than prior art supports, as described herein.

A flexible conduit insulated to prevent unwanted heat transfer. The conduit is insulated by a jacket-like component that creates a space between the conduit and the jacket, where the gap can be filled with air or some other insulating material. The jacket is sealed to the flexible conduit by sealing components that are configured to slide along end cap portions of the flexible conduit. Because the conduit is flexible, it can couple two other conduits that move relative to one another such that fluid can flow from one area to another via the flexible conduit.
