A system and method for coating marine pipeline weld joints and wet inspection of the applied coating is provided. The coating system includes an anti-corrosion coating including a fluorescent pigment to enhance inspection of the applied coating. The system also includes a robotic crawler for traversing inside the pipe and carrying a coating apparatus and inspection apparatus respectively configured to apply the coating on the weld joints and facilitate inspection of the wet coating. The coating apparatus comprises a spraying nozzle provided on a forward end of the robotic crawler and configured to spray coating onto on the surrounding circumferential pipe surface. The inspection apparatus includes an ultraviolet radiation emitter for activating the fluorescent pigment in the coating and a camera for providing a live image feed of the coated weld joint area to an operator computing station for inspection of the applied coating.

Pipe inspection systems including a push-cable, jetter, and camera assembly are disclosed. A jetter nozzle may be configured to spin and/or propel the camera head within a pipe or other cavity. A cutter line may be attached to the camera head to clean obstructions. A sonde may be coupled to a camera head to generate magnetic field signals for use with a buried utility locator to locate a pipe or other cavity into which the camera head is deployed.

Disclosed is a barrel cleaner (10), including a cantilevered lift to raise a barrel, bearings (31, 32) to permit rotation of the barrel once raised, and a spray head support (20) including a spray head. In use the barrel may be rotated so that a bung hole of the barrel is in an insertion position, and the support can be operated to insert the spray head into the bung hole.

Electrical interference signals are to be eliminated during operation and video quality improved in a metal extension sleeve incorporated in an internal space of a nozzle element of a pipe cleaning nozzle and/or inspection nozzle for contacting an electrical conductor via a camera adapter through the internal space of the nozzle element with a camera module fastened outside the nozzle element. The extension sleeve spans the length of the nozzle element and is releasably fastened form-fit and/or force-fit on the camera adapter and the at least one extension sleeve has coupling threads along the outer surface of the coupling section, with which the extension sleeve is tightened in the internal space of the nozzle element. The metal extension sleeve has an electrical insulation layer made of plastic on its outer surface spaced from the central longitudinal axis, which is applied fully to the entire outer surface without defects.

An air purging coater apparatus is disclosed for purging mixed components from the apparatus disposed in a pipeline at a pipeline site. The apparatus includes a remote-controlled apparatus for insertion within the pipeline at the pipeline site. The remote-controlled apparatus includes a drive for controllably moving the remote-controlled apparatus internally within the pipeline. A high-pressure mixing device defines a first and second inlet controllably connected to a pressurized and further pressurized source respectively of a first and second component. The high-pressure mixing device defines a high-pressure mixing chamber connected to the first and the second inlets for mixing together the first and second components. The high-pressure mixing device defines an outlet connected to the high-pressure mixing chamber for receiving a flow therethrough of the mixed components. A spin head defines an internal conical surface and a baffle so that the mixed components are applied to an inside surface of the pipeline. The high-pressure mixing device is controllably movable from an application disposition thereof to a purging disposition. In the purging disposition, the flow of the mixed components is terminated and a source of pressurized air flows into and through the first and second inlets and the high-pressure mixing chamber and the outlet for purging any residual mixed components from the high-pressure mixing device thereby avoiding any need for the use of a potentially hazardous solvent.

A system for applying a chemical agent within a pipe includes a skid assembly, moveable longitudinally within the pipe. The skid assembly has a bottom positionable on a bottom, internal portion of the pipe. A delivery nozzle is carried by the skid assembly and is coupleable to a chemical agent supply. A dispensing tip delivers a controlled stream of chemical agent within the pipe toward an internal surface of the pipe. The tip is held at or above a surface of fluid carried by the pipe while at least a portion of the skid assembly is positioned below the fluid surface. The dispensing tip is limited from delivering the chemical agent downwardly toward the bottom of the skid assembly such that the dispensing tip delivers the controlled stream of chemical agent upwardly away from the bottom surface of the pipe and upwardly away from the fluid surface.

A high-volume low-pressure end effector is presented. The high-volume low-pressure end effector comprises a connection arm and a spray head. The connection arm comprises a housing with flexible conduits running through the housing. The spray head has integral channels configured to receive air and a fluid from the flexible conduits and deliver the air and the fluid to a number of outlets.

A mechanism for applying a predetermined pattern of material onto an elongate tubular substrate includes a first motor, an engagement member rotatable by the first motor and configured to reversibly grasp an elongate member, such that rotation of the first motor rotates the elongate member around its longitudinal axis, a fluid dispenser configured to dispense a fluid having a first, flowable state, the fluid dispenser including an elongate dispensing conduit having a distal end having an orifice, the orifice configured to be placed adjacent a surface of the elongate member, a second motor configured to move at least one of the elongate member or the elongate dispensing conduit such that the orifice changes its relative orientation along the longitudinal axis of the elongate member, and wherein the distal end of the elongate dispensing conduit is configured to apply a bias on the surface of the elongate member.

A device is provided to clean, disinfect, and unclog a plumbing outlet. The device includes a cylindrical body (2) defining a fluid conduit between a first end configured to fit to a tap of pressurized fluid outlet (3). The cylindrical body has a diameter reducer (21) that narrows in diameter from the first end to a second end and forms an internal housing (22). The diameter reducer (22) induces a Venturi effect in water passing therethrough from the tap of pressurized fluid outlet (3). The device further includes a tube in fluid communication with the second end, a dome receiving an end of the tube and configured to surround the plumbing outlet and through which the water passes to clean, disinfect and unclog the plumbing outlet. A bar (5) of detergent or another chemical operative to clean, disinfect or unclog is configured to reside in the internal housing (22).
