An apparatus and related process for the internal cleaning of a pipeline that includes an interchangeable rotary cleaning head, a motor device coupled to the rotary head, a movement device configured to move the apparatus inside the pipeline, and a remote control system. The combined movement of the rotary head rotation and of the advancing motion of the apparatus inside the pipeline allows the disintegration of the deposits present internally of the pipeline by mechanical action.

A sensor apparatus is provided in which both an optical interrogator and an optical waveguide are embedded in the same component made of fiber-reinforced plastic. The optical interrogator and the optical waveguide thus form a unit with the component made of fiber-reinforced plastic, in which they are embedded. The optical interrogator and the optical waveguide are arranged in this case protected in the same component made of fiber-reinforced plastic. The optical waveguide does not have to be led out of this component and into the interrogator. The risk of damage to the optical waveguide is thus significantly reduced.

A pig is provided for use in pipelines filled with a flowing fluid. The pig includes a pig body, a drive element which may be a propeller disposed on said pig body which can be rotated by the flowing fluid. The pig also includes a generator unit connected to the drive element through which a movement of the drive element may be converted into electrical energy, and a locking means through which the position and/or the speed of the pig inside the pipeline may be fixed. The generator unit is designed to operate as a motor through which the drive element may be made to rotate and which is designed to set a speed for the pig that is different from the flow velocity of the flowing fluid inside the pipeline and that the pig is provided with an energy storage unit for electrical energy, which is connected to the generator unit.

Systems and methods of the present disclosure relate to non-intrusively monitoring a fluid level or an object in a conduit. 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 fluid level or the object; and a system controller operable to: receive pressure data from the pressure transducer, the pressure data comprising the pressure responses; and determine a distance of the fluid level or the object in the conduit, relative to the component or the pressure transducer, based on the pressure responses.

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.

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 pig for use in a pipeline is provided for determining the material of the pipeline in the context of an inline inspection. The pig includes a position determination unit and at least one braking arrangement for immobilizing the pig at a certain position in the pipeline. The pig also includes an X-ray fluorescence sensor.

The present invention relates to a device for centring and pulling a tool in a pipeline, the device comprising expanding arms, with each expanding arm comprises a wheel suitable for making contact with an inside wall of a pipeline, wherein each wheel comprises at least one magnetic element.

Systems include a device and a pipeline. The device includes a body. The body includes jetting elements and a sealing disc. The jetting elements include a hose, an opening, channels, and nozzles. The jetting elements are configured to direct pressurized fluid through the body for purposes of cleaning and propelling the device along the pipeline. The sealing discs are configured to maintain a seal between the body of the device and the inside wall of the pipeline.
