A method of cleaning a jet pump assembly of a nuclear reactor may comprise inserting a cleaning tool into the jet pump assembly such that a front face of the cleaning tool is adjacent to an inner surface of the jet pump assembly and below a level of a first liquid in the jet pump assembly. The method may additionally comprise directing a plurality of front jets of a second liquid from a plurality of front orifices on the front face of the cleaning tool such that the plurality of front jets of the second liquid strikes the inner surface of the jet pump assembly. The method may further comprise maintaining a standoff distance between the front face of the cleaning tool and the inner surface of the jet pump assembly during the cleaning of the jet pump assembly.

A drain cleaner includes a base unit having a housing, a drive arrangement positioned within the housing, and a motor coupled to the drive arrangement and supported by the housing. The motor is operable to selectively drive the drive arrangement. The drain cleaner also includes a drum unit removably coupled to the base unit. The drum unit has a drum that engages the drive arrangement when the drum unit is coupled to the base unit to rotate the drum, and a cable stored within the drum and selectively extendable out of the drum and into a drain.

A pipe cleaning robotic device for sludge removal and suction and discharge includes a rail having a plurality of receiving grooves spaced at a predetermined distance on one side thereof; a fixed unit formed at an end of the rail, inserted into a pipe, and fixed in contact with an inner peripheral surface of the pipe; a driving unit mounted on the rail and movable in forward and backward directions along the rail by a wheel drive rotated by an external power; a cylindrical frame for moving and rotating in the forward and backward directions according to driving of the wheel drive; and a sound wave generator formed on one side of an outer circumference of the frame to generate a sound wave to remove the sludge in the pipe cleaning robotic device.

A seam ripping assembly for use in preparing a coiled tubing operation in a production well, such as, for example, in the oil and gas industry. More particularly, the present invention pertains to a method and apparatus for seam dressing that can be used to efficiently remove a weld seam along an inner diameter on a section of coiled tubing, thereby allowing a coil connector to then be able to attach to an end of said section of coiled tubing.
