ABSTRACT:
A tube cleaning lance tip construction for rotation within a tube comprising a body portion, a bore arrangement in the body portion for causing liquid to be ejected with a lateral component creating a reactive force for biasing the body portion toward the inside of the tube, a blade on the opposite side of the body portion from the bore arrangement for removing incrustations from the inside of the tube, the bore arrangement being positioned relative to the longitudinal axis of the body portion to cause the reactive force to be in the direction of rotation of the body portion, and stabilizing blades on the body portion for limiting layover of the blade and for tending to maintain the axis of the lance tip parallel to the axis of the tube and for aiding in the removal of incrustations.
