Abstract
A method is disclosed for securing a repair sleeve within a tubular fluid conveying conduit. The sleeve is positioned within the tube so that it extends coextensive with a region of degraded tube wall and partially beyond the axial extremes of the degraded area. A radially outwardly directed force is then applied to the tubular sleeve from within along a portion of the sleeve at each end, extending beyond the degraded area. The force is sufficient to cause outward plastic deformation of both the sleeve and the tube resulting in an interference mechanical joint therebetween.
