A heat exchanger cleaning device is provided. The cleaning device includes a drive motor configured to rotate a gearbox, a slip clutch, and a support beam about a first axis. The support beam carries a thread rod, a second motor, and one or more carriage assemblies. The carriage assemblies move linearly as the second motor rotates the threaded rod. The carriage assemblies include a support tube for receiving an ultra-high pressure tube therethrough. The carriage assemblies adjust relative to the heat exchanger such that the UHP tube may be inserted through the support tube into a hole of the heat exchanger. Therein the UHP tube may be advanced to clean sediment from the heat exchanger tube.

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.

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.

A first expandable tubular is longitudinally extendable from a housing. The first expandable tubular is expandable to a diameter equal to an internal surface of a wellbore. A first expander is configured to expand the expandable tubular. A second expandable tubular is longitudinally extendable from the housing. The second expandable tubular is configured to expand to a diameter equal to an internal surface of the wellbore. The second expandable tubular is downhole of the first expandable tubular. A second expander is configured to expand the second expandable tubular. The second expander is downhole of the first expander. A sensor is downhole of the second expander. The sensor is configured to detect a presence of a wellbore obstruction proximal to the tool.

A flow management system includes an adjustable compactor configured for attachment to a wall surface of a conduit and being adjustable between an extended configuration and a reference configuration, an electric actuator in fluid communication with the adjustable compactor, and a control module. The control module is configured to control the electric actuator to flow a current to the adjustable compactor to generate an electric field that causes extension of the adjustable compactor for compacting a flow blockage within the conduit to create a channel adjacent the flow blockage and to terminate a flow of the current to remove the electric field at the adjustable compactor to cause the adjustable compactor to return to the reference configuration for opening the channel to a fluid flow within the conduit.

A drive shaft coupling for connecting a rotating tube cleaning shaft to a tube cleaning machine wherein high pressure fluid is pumped through the coupling, wherein the coupling is sealed to contain the high pressure fluid, and wherein a machine driven rotary flexible shaft passes through the coupling.

A linear member transfer apparatus includes: a linear member housing portion having a bottomed cylindrical shape and including: a bottom portion; an opening; a side wall; a restriction portion that is a diaphragm disposed on a position at a predetermined distance from the bottom portion and that has an inner diameter smaller than an inner diameter of the bottom portion; a first chamber configured to house a linear member in a wound state; and a second chamber configured to house the linear member in an extended state; a transfer portion configured to transfer the linear member; and a guide.

An apparatus for accessing longitudinal bores which includes: a length of resilient tube configured to be extendible along at least a portion of its length; wherein one end of the resilient tube includes a utility head thereon; and wherein the other end of the tube is configured to directly or indirectly connect to, and receive a force from, a physical energy source.

Systems, methods, and tools for economically performing downhole well maintenance, utilizing a flexible reinforced hose and maintenance tools designed to work with the hose. Tools include well perforation cleaning tools using water jets and/or brushes, pad removal tools, sand bailing tools, and fluid level meters.

Methods are disclosed for handling cylindrical tubulars in a process that, in preferred embodiments, also performs cleaning, inspection and other operations on the tubular. The tubular is held stationary while it is rotated. During rotation of the tubular, internal and external cleaning systems, and data acquisition systems, pass up and down the length of the rotating tubular. In preferred embodiments, a first tubular is loaded onto the handling machine, whereupon it is indexed and then rotated. Cleaning, inspection and other operations may be performed during rotation. Once operations are complete, the handling system ejects the first tubular while queuing up a second tubular to be loaded.
