A concrete pump hose cleaning device. A receiver mounts to the concrete pump hose at an exit point of the concrete pump hose. The receiver receives and retains a clean out element as the clean out element exits the hose at high velocity. The receiver is constructed and arranged so at to not materially impede concrete and water that is forced from the hose during the cleaning process.

A cleaning installation of a heat exchanger includes a heat exchanger linked upstream to an intake duct for a fluid and downstream to an outlet duct for the fluid. A system is provided for recovering cleaning bodies from the outlet duct after cleaning of the exchanger by the bodies and for reinjecting bodies into the intake duct. The system includes a member capable of being displaced between a first position in which the system is configured to recover and contain cleaning bodies in the mobile member, and a second position in which the system is configured to take fluid from the intake duct and reinject, into this duct, via the mobile member and under the action of the fluid taken, cleaning bodies contained in the member.

The present invention relates to: a tubular medical device cleaning ball; and a manufacturing method therefor and, more specifically, to: a tubular medical device cleaning ball capable of cleaning a tubular medical device by being injected together with a cleaning solution without using a separate brush and the like in order to clean the tubular medical device inserted into the human body during minimally invasive surgery; and a manufacturing method therefor. To this end, the cleaning ball is manufactured as a sphere having surface roughness and a cavity therein.

A pipeline sphere is shown which houses an electronics package. The sphere is formed as a hollow elastomeric body having a predetermined wall thickness and an initially void interior. A carrier tube is positioned within the initially void interior of the sphere and is supported by oppositely arranged carrier plates which are themselves embedded within oppositely arranged end openings of the sphere. A removable inflation valve is contained in one of the valve plates at a first end of the carrier tube. The carrier tube has a plurality of apertures formed through its wall to enable inflating or deflating the sphere. One electronics package that can be used is an electrical tracking device.

A ball circulation pump skid includes a piping manifold mounted to a base frame, having a first inlet and a first outlet each connected to a pump, and provided with a second inlet and a second outlet connectable to an external device. The manifold houses a ball collection capsule configured to permit flow of fluid and entrained cleaning balls into the ball collection capsule in a first flow direction and to permit flow of fluid and entrained cleaning balls out of the ball collection capsule in a second flow direction. Valves mounted to the piping manifold are operative to create alternately a first fluid flow path and a second fluid flow path through the piping manifold, to capture the cleaning balls in the collection capsule prior to fluid flow to the pump and to re-entrain the cleaning balls prior to fluid delivery to the external device.

A cleaning ball with a naturally derived material bonded to a surface of the cleaning ball for a condenser in a power plant is capable of performing efficient cleaning, and even if the material bonded to the surface of the ball is discharged to the ocean, the material does not cause damages to a marine environment. The cleaning ball includes a sponge rubber ball configured to deform and clean a heat transfer tube of the condenser; and a skin layer including crushed sand bonded to a surface of the sponge rubber ball. The crushed sand comprises sandstone containing granite particles, and the crushed sand has a particle size between 0.05 mm and 2.00 mm, and the skin layer is formed in concave and convex shapes on a non-deformed shape of the sponge rubber ball, and is configured to deform corresponding to deformation of the sponge rubber ball.

A system is provided for recovering cleaning bodies from the outlet duct after cleaning of the exchanger by the bodies and for reinjecting bodies into the intake duct.

A deformable pig and method of pigging are disclosed. The deformable pig is an outer shell having a hollow, spherical shape and a deformable core material contained within the outer shell. The deformable core material may be a shape memory polymer foam which will contour to bends in a pipeline being treated. This enables effective cleaning of the pipeline while inhibiting the pig from getting stuck in the pipeline. Alternatively, the deformable pig may be made from the shape memory polymer foam and be rectangular shaped without an outer shell material.

A pipeline pig system is adapted to clean a pipe before applying a chemical to an interior wall of the pipe. The pipeline pig system includes a cleaning pig and an applicator pig. The applicator pig is configured to follow behind the cleaning pig as the cleaning pig and applicator pig move in a lateral direction through the pipe. Examples of chemicals include one or more of a corrosion inhibitor, a biocide, a paraffin inhibitor, an asphaltene inhibitor, a surface wetting agent, a cleaning compound, an iron chelator, a solvent, a dispersant, a surfactant, an internal film forming material, and a drag reducer.

In a pipeline inspection system, a hollow spherical ball has an internal ultrasonic vibration module, an internal battery for powering the vibration module, and an internal, wirelessly operated, control for controlling the vibration module while the ball is moving, with liquid, along the pipeline. Liquid, having a reduced oxygen content, is pumped through the pipeline, and filtered before returning to the pipeline. Each of a plurality of holes, connecting the interior to the exterior of the ball, is tapered proceeding in the direction from the interior to the exterior, resulting in the formation of a blade structure where the interior of each hole meets the outer surface of the ball at an inclined angle. When the blade structure is in contact with the wall of the pipe, and caused to vibrate by the vibration module, it is able to cut off scale from the interior of the pipe.
