  • Pressure actuated cleaning tool
    Patent number: 4799554
    Abstract: Apparatus for pressurized cleaning of flow conductors. The apparatus has a first mandrel and a second mandrel telescoped therein. A cleaning tool can be attached to the second mandrel. Changes in fluid pressure flowing through the mandrels will cause the second mandrel to rotate relative to the first mandrel. Rotation is used to direct fluid jets in the cleaning tool towards different portions of the interior of the flow conductor. Rotation of the cleaning tool can also be used for hydraulic drilling of deposits within the flow conductor.
