A machine comprising: a lance, the lance configured to clean insides of tubes; a guide way positioned near the tubes; a transversal drive support slidable on the guide way and configured to move the lance along the guide way towards an insertion head; a rotational drive coupled to the lance for controlling rotation of the lance; and a feeding system coupled to the lance, wherein the guide way forms at least one supporting lance channel over a length of the guide way, the at least one channel forming an enclosure from all sides for guiding the lance, whereby a part on the circumference of the enclosure is made of a flexible lip, which lip can be locally bent by deflectors travelling with the lance.

A tool for cleaning out the lower end of a cased wellbore having an installed production string. The tool is lowered down the production string until it projects from an end of the production string and into the wellbore. High pressure fluid is then sprayed from the tool’s fluid openings into nearby portions of the wellbore. Once cleaning operations are complete, the tool is carried back to the ground surface using subterranean fluid pressure.

A system and an apparatus for positioning a plurality of flexible cleaning lances through tubes penetrating a tube sheet of a heat exchanger tube sheet, includes a smart lance tractor drive, a controller, and a tumble box connected to the controller operable to generate and/or distribute electrical power to the AC induction sensor from an air pressure source, supply electrical power to the controller and distribute pneumatic power to pneumatic motors for positioning the tractor drive on the positioner frame. The smart tractor drive includes sensors for detection of mismatch between expected and actual lance positions, sense lance insertion distance and lance removal and provide automated drive reversal operation to remove blockages within tubes being cleaned.

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.

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.

Effluent containment devices are made of flame-resistant material having a Flame Spread Index of greater than zero and less than 30. The material may also have anti-static properties, such as being formed of a dissipative material or one that resists flow electrification.

A method of cleaning the inside of a pipework includes selecting a section of the pipework to be cleaned and determining a hold point of the pipework. A cleaning apparatus is inserted into an entry point of the pipework section, the apparatus being coupled to a fluid supply and equipped to blow the fluid along the pipework section from the first or last hold point to the entry point. The apparatus further includes an image recorder to obtain a visual record of the inside of the pipework. Insertion of the apparatus into the pipework continues until the apparatus reaches the hold point. A collector is secured over the entry point to collect debris blown from the pipework, and fluid supply is activated. The apparatus is moved from the hold to the entry point, so blowing debris towards and into the collector. On completion, the fluid supply is deactivated and the collector containing the collected debris removed from the entry point.

A pipe coating removal apparatus (1) for removing all or some of the coating on a pipe, the pipe coating removal apparatus (1) having a pipe support means (2) for supporting a length of pipe. and further having a tool carriage (3). The tool carriage (3) being capable of supporting two or more different types of pipe coating removal tools (4), (5), (6), (7), (8), (80), (81), (82) and/or (70). The pipe coating removal apparatus (1) being capable of causing relative movement between the tool carriage (3) and the pipe support means (2) to remove all or some of the coating on the pipe that is supportable by the pipe support means (2).

A cavity cleaning and coating system for safely and efficiently cleaning and coating the interior of a cavity without requiring entry of any workers. The cavity cleaning and coating system generally includes a mount which is coupled with a movable arm of a vehicle. The mount includes an inner plate, which is coupled to the arm, and an outer plate. A shaft is coupled to the outer plate. The mount is adjustable independently of the arm of the vehicle, including outwardly, inwardly, and rotatably. A spray head is connected to the shaft. The spray head is rotatable and includes a dispenser for dispensing fluids. The vehicle is positioned near a cavity to be treated. The mount is adjusted for optimal positioning of the spray head. The spray head is lowered into the cavity to dispense a cleaning fluid and, after the cleaning fluid has dried, a coating fluid.

Cleanout tools and related methods of operation. At least some of the example embodiments are cleanout tools including a tool body that defines an internal annular channel, a joiner coupled to the tool body, a sleeve telescoped within the joiner and tool body, and a ball disposed within the annular channel. The ball held within the annular channel by the sleeve, and the ball configured to move along the annular channel under force of fluid pumped into the cleanout tool. The ball creates a pulsing of fluid streams exiting the tool body. Moreover, in some example systems the fluid streams created by the tool body intersect the inside diameter of a casing at non-perpendicular angles.
