Abstract

The invention provides an apparatus and methods for duct leakage control wherein a sealing element is introduced into the duct and is automatically drawn or otherwise guided to the locality of a leak, the element being caused, by reason of a pressure differential attributable to the leak, to move into and stem or seal the leak. The sealing element may comprise a plurality of individual members of differing buoyancy, each capable of being carried along at a predetermined level in the duct by the flow of fluid therein. The sealing element may carry a tagging device which can be used to assist in locating the leakage site.
