Abstract
A metallic sleeve for bridging a leakage point on a pipe is expanded onto the inner wall surface of the pipe with the aid of an expansion technique. During the expansion process, a gap of approximately 5 to 10 .mu.m occurs between the pipe and the sleeve due to the elastic resilience of the deformed materials. In order to prevent leakage through this gap, the peripheral surface of the end regions of the sleeve carry a component made of a shape-memory alloy which forms a seal between the sleeve and the pipe when a given temperature is reached. The sleeve is used primarily during the repair of heat exchanger tubes.
