ABSTRACT:
An apparatus for cleaning the inside faces of pipes or tubes from foreign particles sticking thereto, by means of flexible cleaning elements which are oversized relative to the pipe/tube inside diameter to be cleaned, and which are forced through the pipes or tubes under hydraulic pressure is provided, wherein a bar screen disposed on the downstream side of the pipe/tube outlet separates the cleaning elements from the liquid. The apparatus includes a drum-shaped rotatable body having its axis of rotation disposed in a plane normal to the liquid stream direction of flow, on the inside of which there is a screen body or element arranged under such an angle relative to the direction of flow that a lower screen face extremity opens out into an outlet opening.
