ABSTRACT:
The present invention relates to an improved method of cleaning and removing the products of corrosion, oxidation and sedimentation which occur within and become attached to the walls of the interior of heat exchanger tubes which are located within a pressure vessel such as a tube bundle heat exchanger, boiler, condenser or the like, through utilization of a repetitive shock wave induced into a liquid which is placed within the tubes and then subsequently flushing the tubes. The shock wave serves to effectively and safely loosen the products of corrosion, oxidation and sedimentation which are located within or settle on the walls of the interior of the heat exchanger tubes, and thereby facilitates their easy removal through flushing and vacuuming the vessel. The shock waves are induced by air-gun type pressure pulse shock wave sources or pressurized gas-type pressure pulse shock wave sources.
