The present invention is directed to a method of cleaning and inspection of drilling mud carrying flow lines, each flow line having an inner surface. The method includes affixing a fitting to the flow line, the fitting having a main flow channel and a branch flow channel extending at an angle from said main flow channel. A first end portion of the fitting can have an attachment that enables connection of the fitting to the flow line at one flow line end portion. A second end portion of the fitting can have one or more doors that can be moved between opened and closed positions, the door or doors providing an opening that is not closed when the doors are in the closed position. A suction line can be connected to the branch flow channel. A cleaning tool can be guided first into the fitting and then into the flow line using a fluid carrying cable. The cleaning tool and jetting fluid can be used to clean drilling mud and debris from the inner surface of the flow line. The jetting fluid can be removed via the branch flow channel using the suction line. The cable can extend through the door opening or openings when the door or doors are in the closed position. A camera can be guided into the flow line using a camera cable wherein the camera cable extends through the door opening or openings. The cleaning tool is preferably too small to fit through the door opening.

A pipe cleaning tool for cleaning pipe surfaces is configured for operative engagement with a drill motor. The cleaning tool includes a body having a sidewall extending between a first end and a second end of the body. Cleaning blades located in each of a plurality of slots which extend to respective openings in the sidewall of the body. The cleaning blades are biased to project past the sidewall and thereby contact a pipe surface positioned adjacent the sidewall to clean the pipe surface of oxidation and dirt when the body of the cleaning tool is rotated by the engaged drill motor.

A pig is provided for passing through a pipeline having a pipeline wall. The pig comprises at least one functional unit for cleaning the pipeline and/or for receiving pipeline information. The pig also comprises at least one magnet unit which is provided for magnetizing the pipeline wall, and which has a plurality of magnets. The magnet unit has a plurality of segments each with at least one magnet. The magnetizing devices of mutually adjacent segments are angled at least by approximately 90° to one another.

A motorized apparatus for use in maintaining a pipe having a sidewall is provided. The motorized apparatus includes a body assembly sized to fit within and to travel along an interior cavity of the pipe. The body assembly includes a first end and a second end and extending along a longitudinal axis. The body assembly also includes a plurality of leg assemblies coupled circumferentially around the body assembly. Each leg assembly includes a telescoping portion, a bias member coupled to the telescoping portion, and a drive mechanism configured to interact with the sidewall as the body assembly travels along the pipe. The body assembly also includes at least one sensor configured to collect data associated with a force between the sidewall and the drive mechanism, and an actuator assembly coupled to each leg assembly and configured to independently actuate each the leg assembly.

A high pressure jetting system for use with a water supply system includes a recirculating unit to connect to an isolated section of the water supply system. The isolated section remains under water supply system pressure. The recirculating unit includes a filter unit and a pump unit capable of generating a circulating flow of water. A first pig launch and recovery apparatus couples a first hydrant to the recirculating unit and a second pig launch and recovery apparatus couples a second hydrant to the recirculating unit. A jetting unit including a jetting head is coupled to a jetting hose. The jetting unit enters the closed circuit through the second pig launch and recovery apparatus and travels within the isolated section. The jetting head emits a plurality of water jets to assist removal of material from an inner surface of the water mains and pipes.

The group of inventions can be used for removal of deposits in sewers and the simultaneous removal thereof in various pipelines, providing mechanization of the cleaning process in a sewage pipeline and eliminating the need for disassembling the drain system and manually cleaning it. A movable element and a cleaning tool mounted thereon, both arranged within the sewage pipeline, are moved along the sewage pipeline by means of a drive mounted outside the sewage pipeline and connected to the movable element. In the initial position, the cleaning tool is located at the end of the sewage pipeline, outside the sewage pipeline portion connecting the drain pipe with a riser. When the cleaning tool reaches the end position at the junction of the sewage pipeline and the riser, the drive and the movable element move the cleaning tool to its initial position.

An apparatus and related method are provided for loading a pig into a pipeline. The apparatus includes a tubular reducer, a rigid member including a pig-engaging surface, and a guide member slidingly engaged by the rigid member to permit axial movement, while limiting radial movement, of the rigid member in relation to the reducer. In use, when the reducer is aligned concentrically with the pipeline end with the front end of the reducer bearing axially, either directly or indirectly, against the pipeline end, and the pig-engaging surface is disposed axially rearward of the reducer, increased tension in the cable pulls the rigid member axially forward relative to the pipeline, whereupon the attached pig-engaging surface pushes the pig through the reducer and into the pipeline interior.

Systems and methods of the present disclosure relate to non-intrusive tracking of objects in a conduit from a single location. A system comprises a component positioned to control flow into or out of the conduit to induce pressure waves in the conduit; a pressure transducer in fluid communication with the conduit, the pressure transducer positioned to measure pressure responses in the conduit due to contact of the pressure waves with the object; and a system controller operable to: receive pressure data from the pressure transducer, wherein the pressure data includes the pressure responses to the pressure waves; and determine a distance of the object in the conduit, relative to the component or the pressure transducer, based on the pressure responses.

A high pressure jetting system includes a recirculating unit connected to an isolated section of a water supply system which remains under system pressure. The recirculating unit includes a filter unit and a pump unit generating a circulating flow of water. A first pig launch and recovery apparatus couples a first hydrant to the recirculating unit and a second pig launch and recovery apparatus couples a second hydrant to the recirculating unit. A camera unit including a camera and drogue chute enters through the first apparatus and travels in a flushing flow direction to the second apparatus. The drogue chute is then removed from the camera. The camera then couples to a jetting unit having a jetting head and hose and re-enters through the second apparatus. The jetting unit emits a plurality of water jets to move in a counter-current flow direction and remove material from the water mains.
