Abstract
The invention relates to a method for the continuous cleaning of the inside of a tube in which a fluid circulates, in which method there is continuously driven in rotation within the tube by the fluid a movable element, one end of which is fastened to one end of the tube through a mechanical linkage permitting it to rotate freely on itself about the axis of the tube. In accordance with the invention, the movable element comprises at least one sharp edge designed to scrape the inner surface of the tube, this edge being disposed so that during the rotation of the movable element it is, along every cross section of the tube, the portion of the movable element farthest removed from the axis of the tube.
