A thermal insulating sleeve liner for fluid flow devices such as valves and piping used in severe industrial applications is preferably additively manufactured (e.g., by 3D printing) to fit into the bore of a protected fluid flow device. Internal interstices and/or external ribs provide added thermal insulation. An integrally formed end-lip or a separate end-cap secures and/or locates the sleeve liner within the protected fluid flow device between different diameter distal and proximal portions of the bore. If internal interstices are sealed they can be vacuumed or pressurized to enhance thermal insulating properties. Fitted dimensions are sufficiently small to prevent ingress of thermally conductive particles circulating in use within the flow path of the protected flow device. A pressure equalizing aperture can be provided on or through the sleeve if needed in some applications.

The present disclosure provides a valve apparatus that prevents defects in the valve apparatus and prevents damage to the heat insulating material due to a cryogenic liquid fluid, and a semiconductor processing device including the same and a manufacturing method thereof.

An apparatus and method for sealing an end cap on an insulated pipe system is provided. A flexible body having a top, a bottom, a first side and a second side acts to prevent the ingress of moisture into an insulated pipe system at the connection between the end cap and the pipe. The top of the flexible body has an end cap receiver. The bottom of the flexible body circumferentially engages the pipe. The flexible body is sealable to the pipe by a sealant. The end cap receiver accepts an edge of an end cap. A flexible band circumferentially engages the flexible body to hold the flexible body on the pipe.

A line set seal comprising a pipe sealing end and an insulation sealing end, wherein the insulation sealing end is larger than the pipe sealing end, wherein the pipe sealing end is configured to seal to a pipe, and wherein the insulation sealing end is configured to seal to insulation.

Exemplary embodiments are directed to a pipe valve insulation cover. The cover includes a flexible sheet including a first side and a second side positioned over each other in a substantially overlapping manner. In the overlapping configuration, the flexible sheet defines a top edge, a bottom edge opposing the top edge, a right edge, and a left edge opposing the right edge. The flexible sheet defines a hollow interior in the overlapping configuration. The cover includes a first opening formed in the flexible sheet at or near the top edge, a second opening formed in the flexible sheet at or near the right edge, a third opening formed in the flexible sheet at or near the left edge, and a fourth opening formed in the flexible sheet at or near the bottom edge.

A transition section disposed between successively spoolable, electrically trace-heated PiP pipelines comprises an inner pipe, an outer pipe, and an annulus between the inner and outer pipes. The annulus contains heating cables that extend longitudinally between annuli of the pipelines and longitudinally spaced seals that, when deactivated, allow fluid communication between the annuli of the pipelines and, when activated, isolate the annuli of the pipelines from each other. Longitudinally spaced blocking plates close the lumen of the inner pipe and define an inner chamber between them. Longitudinally spaced openings penetrate a wall of the inner pipe at locations longitudinally inboard of the blocking plates and the seals. The openings effect fluid communication between the annulus and the inner chamber and also define a diversion path for the heating cables that extends from the annulus to the inner chamber and back to the annulus.
