Abstract: The present disclosure relates to a method for repairing a partially collapsed pipe. The method comprises fitting a mesh stent around the outside of an actuation assembly of a pipe repair apparatus, and positioning the pipe repair apparatus within a portion of the pipe, at least a part of the portion of the pipe being partially collapsed. The method also comprises causing actuation between a retracted configuration and an extended configuration such that the partially collapsed part of the pipe changes from a partially collapsed form towards a non-collapsed form. The method also comprises removing the pipe repair apparatus from the pipe and leaving the mesh stent in the portion of the pipe.

Abstract: A cutter is provided for cutting through obstructions disposed in the interior of pipes ranging in size from approximately 8″ to approximately 15″ in diameter or from approximately 12″ to approximately 24″ in diameter. The cutter has been reduced in size relative to known root cutters to be capable of being used with smaller-diameter pipes, but is sufficiently powerful to cut through obstructions, such as mineral deposits, for example, that known flexible cutters capable of being used with these smaller-diameter pipes are incapable of cutting through.

Abstract: A cleaning pig assembly is provided for use on a tubular drag conveyor. The assembly is quickly and easily mounted anywhere along the cable, chain, or rope via slots in the assembly components. The components include a puck, a plate, a drag disc, and a cleaning member or tool sandwiched between the puck and the plate. The drag disc provides interference fit on the cable, chain, or rope holding the assembly on the cable, chain, or rope and prevents sliding of the assembly along the cable, chain, or rope during use. The cleaning assembly is installed without the use of tools or clamps. Multiple interchangeable cleaning members are provided depending on cleaning needs.

Abstract: A spray coating system includes a spraying robot sized to fit within a conduit. The spraying robot includes arms that extend outward and retract inward to maintain contact with an interior surface of the conduit. The spraying robot is configured to be coupled with hoses that separately supply different fluids to the spraying robot. The spraying robot includes a spray head from which a compound formed from the fluids is sprayed onto the interior surface of the conduit. The spraying robot is configured to be pulled through the conduit and/or self-propel in the conduit to spray the compound onto the interior surface of the conduit and form a coating thereon.

Abstract: A carrier assembly (10) engages a pipe ring for installing the pipe ring in an existing pipeline to repair the existing pipeline. The carrier assembly (10) has a chassis assembly (12), a support arm assembly (14) and a drive system (16). The chassis assembly (12) has the support arm assembly (14) operably connected thereto. The drive system (14) is operably connected to the chassis assembly (12) wherein the chassis assembly (12) is configured to move along the pipeline. The support arm assembly (14) is configured to engage the pipe ring wherein the support arm assembly (14) is moveable relative to the chassis assembly (12) to displace the pipe ring relative to the chassis assembly (12) for installation in the existing pipeline.

Abstract: A system and method for measuring an inside diameter of a pipe to determine if it exceeds a predetermined value using a plurality of fingers operatively connected to a spring. When in a fully extended position, the distance between opposite fingers is the predetermined value. The fingers are pivotable between a starting position, through the fully extended position, and to a failing position. In the starting position, an outer end of each finger engages an inside surface of the pipe to compress the spring. If the diameter exceeds the predetermined value as the system moves through the pipe, the pipe inside surface will no longer engage the fingers, which releases the spring causing the fingers to pivot to the failing position, where they remain until the system is removed from the pipe and manually reset.

Abstract: A caliper pig for detecting geometrical deformation of a pipeline is disclosed. The caliper pig includes a body and a first sensor arm assembly. The first sensor arm assembly includes a primary caliper sensor ring adapted to be mounted on the body. Further, the first sensor arm assembly includes a plurality of sensor arms adapted circumferentially distributed on the primary caliper sensor ring. Each of the plurality of sensor arms includes a sensing arm adapted to be in contact with an internal surface of the pipeline and a pair of magnets adapted to rotate along the sensing arm. Each of the plurality of sensor arms includes a sensing unit configured to detect a change in magnetic field based on the movement of the sensing arm. The sensing unit is configured to generate an output indicative of an angle of deflection of the sensing arm while traversing on the internal surface of the pipeline.

Abstract: A pipeline pigging element (10) that changes its size in an axial and a radial direction as a function of applied pipeline pressure. The pigging element includes at least two circumferential zones (13, 15) having different section modulus than one another, each of the zones changing at different rates from one another between an uninflated and an inflated state at the applied pipeline pressure. The pigging element reacts to changes in pipe geometry, having a first length and a first diameter at a first applied pipeline pressure and a second length and a second diameter different than the first at a second applied pipeline pressure. As the pigging element wears, it becomes easier to inflate at the applied pressure and sealing contact with the pipe wall remains substantially unaffected. No onboard pumps or fluid circuits are required to inflate the pigging element.
