A pipe cleaner M4 tool comprising an elongated body having 30 degrees arch, a first end and a second end. Further, the first end and the second end have respective sharp edges to facilitate scrapping action. In addition, the elongated body is biased towards a curved shape, and facilitates spring like action, when moved in a clogged component, to aid in cleaning. The pipe cleaner tool is made of Polylactic Acid (PLA) material.

A method of prepping a cylindrical inner surface of a bore using a high-frequency forced pulsed waterjet apparatus entails generating a pressurized waterjet using a high-pressure water pump, generating a high-frequency signal using a high-frequency signal generator, applying the high-frequency signal to a transducer having a microtip to cause the microtip to vibrate to thereby generate the high-frequency forced pulsed waterjet, and rotating the rotatable ultrasonic nozzle inside the bore to prep the inner cylindrical surface of the bore using the high-frequency forced pulsed waterjets exiting from the angled exit orifices of the rotatable ultrasonic nozzle.

A system includes an inspection robot having mounted sleds, and a number of sensors each mounted to a sled. A couplant chamber is disposed within at least two of the sleds, each couplant chamber between a transducer of the sensor and an inspection surface. Each couplant chamber includes a cone, the cone having a cone tip portion at an inspection surface end, and a sensor mounting end opposite the cone tip portion. A couplant entry for each couplant chamber is at a vertically upper side of the cone in the intended orientation of the inspection robot on the inspection surface.

A pressure medium-operated pipe cleaning device for streak-free cleaning of the pipe and duct wall and simultaneously a video recording of the entire cleaning process. The device includes a nozzle module and a camera module. The nozzle module includes a plurality of thrusters and a plurality of cleaning nozzles, and the camera module has at least one camera, an illuminating device, control electronics, a memory, a transmitter and an accumulator, so that the camera module can be controlled from outside by the control electronics. The nozzle module and camera module separately designed in terms of location and construction, and mounted on a carriage spaced linearly apart from each other in the direction of a longitudinal axis by a distance, wherein a stator part has the thrusters of the nozzle module and the camera module is rotationally and linearly immovably fastened to the carriage, while the rotor part on which the plurality of cleaning nozzles are arranged can be rotated around the longitudinal axis.

A method for cleaning the interior of a pipe using a cleaning device which has a tube. The tube is set into an axial movement along a main axis H within the pipe, and the insertion depth E of the tube into the pipe is detected. It is determined whether the tube has reached an end position, and the axial movement is terminated when the tube reaches the end position.

A method for operating a conduit inspection tool in a conduit includes positioning a conduit inspection tool in the conduit, the conduit inspection tool including a body that includes one or more wheels, at least two power generating sub-systems coupled to the body, and at least one energy storage device electrically coupled to the at least two power generating sub-systems; moving the body through and in contact with the conduit through the one or more wheels; generating electrical power by at least one of the at least two power generating sub-systems by the movement; and providing at least a portion of the generated electrical power to the at least one energy storage device to store the portion of the generated electrical power.
