Title: Method for the cleaning of heat exchange tubes and collecting device for the collection of deposits from heat exchange tubes

Abstract: A method for the cleaning of heat exchange tubes and a collecting device for the collection of deposits from heat exchange tubes, include releasing deposits and collecting the deposits with a collecting vessel. The collecting vessel has an inlet orifice that completely encloses the underside of a tube plate in which exit-side tube ends are disposed. The collecting vessel has an inflatable hose for sealing off the collecting vessel. The collecting vessel is capable of being folded together, so that it can be introduced through a service orifice into the heat exchanger. The collecting vessel provides simple handling and positioning and serves, in particular, for use in a nuclear plant.
