Abstract: A system and method for bypassing a rupture in a pipeline with a magnet and a bypass assembly. The magnet is placed outside the pipeline proximal the rupture. The bypass assembly is positioned inside the pipeline. The bypass assembly has a hollow cylinder, an expansion tube disposed about and slidable relative to the hollow cylinder, expansion ring sub-assemblies which expand from the expansion tube from a stored position to an extended position responsive to the expansion tube sliding, and a ferromagnetic tail extending from the hollow cylinder. The ferromagnetic tail articulates to contact an inner surface of the pipeline responsive to the magnetic field of the magnet. The ferromagnetic tail contacting the inner surface of the pipeline directs a fluid flow to the expansion tube, moving the expansion tube from the first position to the second position and shifting the expansion ring sub-assemblies to the extended position.

Abstract: A coating device for coating an internal wall of a hollow vessel is disclosed. The coating device comprises a body defining an internal chamber, a flowable coating material stored in the internal chamber, a cavity defined in the body, a coating delivery member supported in the cavity, the coating delivery member movable between a first position and a second position, and a channel defined in the body. The channel extends between the cavity and the internal chamber, wherein the coating material flows out of the internal chamber through the channel, wherein the coating delivery member prevents the coating material from flowing out of the channel when the coating delivery member is in the first position, and wherein the coating delivery member facilitates the coating material to flow out of the channel when the coating delivery member is in the second position.

Abstract: A system for determining conditions within a pipeline comprises a testing platform comprising a magnetically attractable component and at least one testing component, a magnetic positioning system comprising a platform engaging magnet and a three-dimensional positioner configured to position the platform engaging magnet longitudinally and circumferentially along an exterior surface of the pipeline, wherein the magnetic positioning system is configured to selectively maintain the testing platform at a plurality of positions within the pipeline via through-wall magnetic coupling between the platform engaging magnet and the magnetically attractable component of the testing platform.

Abstract: A flow redirecting device is disclosed having a telescoping mechanism including an inlet telescoping member and an end telescoping member. The inlet telescoping member is an annular wall having a first proximal diameter and a first distal diameter less than the first proximal diameter, and the end telescoping member has an open end and a closed end, the open end having a second proximal diameter less than the first proximal diameter. The telescoping mechanism has a retracted configuration in which the end telescoping member is nested inside of the inlet telescoping member, and the telescoping mechanism has an extended configuration in which the inlet telescoping member and the end telescoping member are arranged end to end to define a flow path that narrows from the first proximal diameter of the inlet telescoping member to the second proximal diameter of the end telescoping member.

Abstract: A system for determining material degradation conditions within a pipeline comprises a degradation monitoring device comprising a magnetically attractable component and a magnetic positioning system comprising a device engaging magnet and a three-dimensional positioner configured to position the device engaging magnet longitudinally and circumferentially along an exterior surface of the pipeline, wherein the magnetic positioning system is configured to selectively maintain the degradation monitoring device at a plurality of positions within the pipeline via through-wall magnetic coupling between the device engaging magnet and the magnetically attractable component of the degradation monitoring device.

Abstract: A pipeline valve includes a body section including a bore configured to circulate a pipeline fluid therethrough. The body further includes one or more expandable seals configured to seal against an inner surface of a pipeline. The pipeline valve includes a tail section coupled to the body and including at least one ferromagnetic finger that extends from the tail section. The at least one ferromagnetic finger is configured to magnetically couple to the inner surface of the pipeline in response to a magnetic field generated by at least one magnet positioned on or adjacent an external surface of the pipeline to anchor the tail section to the pipeline. The pipeline valve includes a valve section coupled to the body section and the tail section. The valve section is configured to adjust a flow of the pipeline fluid through the bore.

Abstract: A system for chemical processing includes a hollow structure including a side wall having an exterior surface and an interior surface defining an internal volume. The hollow structure has a center axis, a length, and an outer perimeter. The outer perimeter is a shape of the exterior surface of the side wall of the hollow structure in a plane perpendicular to the center axis. The system includes a metallic object positioned within the internal volume of the hollow structure. The system also includes at least two magnets slidably coupled to the exterior surface of the side wall, where the magnets guide movement of the at least one metallic object within the hollow structure. The magnets operate to impact the metallic object against the solid deposits to loosen the solid deposits from the interior surface of the side wall.
