Abstract
A multi-lance cleaning apparatus for cleaning the interior of heat exchanger tubes, the apparatus having a lance housing, a slidable manifold within the lance housing, a single conduit connecting the manifold with a high pressure, high volume, fluid source, a hose enclosure for enclosing the high pressure water hose permitting the hose to advance and retract, means for moving the manifold within the housing, a plurality of lances removably attached to the manifold and adapted to fit within a heat exchanger tube, tube guides to guide and support the lances, and a slide plate on which the manifold is located for preventing the lances from bending and entering the hose enclosure. The apparatus may further include means for positioning and guiding the housing with respect to a heat exchanger tube bundle to be cleaned.
