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.
Claims7
A pipe sheath repair apparatus comprising:
- a sleeve adapted to surround a pipe;
- a first collar disposed at a first end of the sleeve;
- a second collar disposed at a second end of the sleeve;
- a first reservoir disposed in the first collar and a second reservoir disposed in the second collar;
- a first sealing arrangement disposed between a surface of the pipe and the first collar and a second sealing arrangement disposed between the surface of the pipe and the second collar;
- a first sealing solution disposed in the first reservoir and the second reservoir, the sealing solution being forced, via pressure in the first reservoir and the second reservoir, against the surface of the pipe between the first and second sealing arrangements, respectively, when the apparatus is installed;
- and
- wherein the sleeve comprises a plurality of modules that flex relative to one another the plurality of modules being arranged such that the sleeve is spaced from an outer sheath of the pipe to form a sealed annulus and a second sealing solution is introduced into the sealed annulus.
