  • Patent number: 11065630
    Abstract: Disclosed herein is a tool for holding a spray painting instrument, such as a painting gun for painting an internal surface of a pipe. In particular, the inventive tool is ideal for painting the interior of curves and angles in a pipe and is capable of moving through and uniformly painting up to 90 degree angles of pipes or hollow tubes. The tool has a hollow central tube for carrying a spray-painting gun and at least two projections extending outwardly from an outer surface of the hollow tube. A retracting arm assembly is provided on each projection. Each retracting arm assembly includes first and second retracting arms and a corresponding force exertion mechanism. In operation, when the tool is inserted inside the pipe, each retracting arm touches the internal surface of the pipe due to an outward force exerted thereon. The tool is movable inside the pipe and adjusts automatically to different pipe diameters.

  • Patent number: 10960425
    Abstract: A material delivery assembly includes a delivery fitting attached to a drive shaft and including an outer wall that extends perpendicularly from a receiving surface. Apportioning slots are defined within the outer wall. A dispersion chamber is defined within the outer wall and the receiving surface. A material delivery conduit extends to a delivery port located within the dispersion chamber and is proximate the receiving surface of the delivery fitting. The material delivery port selectively delivers a viscous material to the receiving surface. The drive shaft and the delivery fitting are rotationally operated to define an apportioning state of the delivery fitting that is configured to manipulate the viscous material toward an inner surface of the outer wall. The apportioning slots in the apportioning state are configured to regulate passage of the viscous material from the dispersion chamber, through the outer wall and into a disk-shaped spread pattern.

  • Patent number: 9939389
    Abstract: A data acquisition system for determining the state of a tubular while the tubular rotates about its cylindrical axis. The tubular remains otherwise substantially stationary. Sensors travel up and down the length of the rotating tubular, interrogating the inside and outside of the tubular for data regarding the tubular's state. Sensors may take samples which may be associated with rotational reference information tying the sample to its absolute position on the internal or external surface of the tubular. A data processor processes the samples and other sensor data to produce a wide array of output, including data signatures of the tubular, maps of contour data regarding the internal or external surface of the tubular, and dimensional data regarding the tubular. Data acquisition is advantageously done in real time, and may further be done concurrently with internal or external cleaning operations.

    Abstract: An in situ apparatus, system, and method for cladding or repairing cladding in installed pipelines are presented. The apparatus can include a coating collar, a material reservoir, a cladding head, an adjustable cladding chamber, and a chamber controller. The coating collar can include an external surface, a first circumferential wall, and a second circumferential wall and forms the adjustable cladding chamber along with interior wall of the pipe. The coating collar can have an aperture to include and allow deployment of the cladding head through it. The cladding head can be operatively coupled with the cladding material reservoir to allow efficient deployment of the cladding material on the pipe surface. The chamber controller can be coupled with the adjustable cladding chamber to control dimensions of the chamber thus restricting and controlling the environment and enabling efficient functioning of the cladding head and limiting grain growth in applied nanoclad materials.

  • Patent number: 8757086
    Abstract: The interior of a straight pipe is clad using a plurality of welding heads. The pipe is carried on support rollers including drive components for rotating the pipe about its axis while holding it fixed against axial movement. There are four welding heads with two carried on a cantilevered support arm of a respective one of a first and a second carriage mounted outside the pipe at opposite ends of the pipe and each movable in a direction longitudinally of the axis of the pipe. The heads are located on the arm at a common angular position at bottom dead center to weld vertically downwardly. The pipe support includes a pair of drive rollers arranged with their axes parallel to the axis of the pipe and adjustable in spacing to change the height of the pipe on the rollers relative to the welding heads.

  • Patent number: 8584615
    Abstract: A spray assembly includes a power source, a motion control mechanism such as a cam box, and at least one spray head structured to apply a coating to a plurality of can ends. Each spray head includes a mounting member, a pivot member, a gun assembly including a plurality of spray guns, and a transfer mechanism for transferring a predetermined motion induced by the cam box from the cam box to the pivot member. Each of the spray guns applies the coating to the can ends in accordance with the predetermined motion. Preferably the predetermined motion as an oscillating motion transferred to the pivot member by belts, thereby oscillating the spray guns. The spray assembly may include a plurality of spray heads, wherein can ends of the same or different sizes are transferred in lanes to a corresponding one of the spray heads.

  • Publication number: 20130280424
    Abstract: A planetary gear retrieval system for pulling a sled at a constant velocity along an interior of a pipe, and a sled for applying a coating material to the interior of the large-diameter pipe. The planetary gear retrieval system is connected to the sled via a chain, and has a network of gears controlled by a first variable speed microcontroller. A spinner on a linear oscillating plate provided on the sled is controlled by a second variable speed microcontroller. The first and second microcontrollers are programmable to be synchronized with one another so as to pull the sled at a desired constant rate and achieve a desired number of passes of the spinner along a given length of pipe while the sled is pulled at the desired rate.
