Abstract
An apparatus for repairing a sheath of a pipe includes a sleeve adapted to surround the pipe, at least two circumferential seals between the surface of the pipe and a pressure source for forcing a sealing solution against the surface of the pipe between the two circumferential seals. The apparatus is arranged such that the sleeve is spaced from the outer sheath of the pipe to form a sealed annulus and a sealing solution is introduced into the sealed annulus.
