Abstract
An apparatus for radially expanding and plastically deforming a tubular member. In some embodiments, the apparatus includes a tubular support, sliding sleeve, rupture disc, and expansion cone. The tubular support has a first internal passage, wherein the sliding sleeve is disposed, and a flow passage, wherein the rupture disc is seated. The sliding sleeve has a second internal passage and is moveable by fluid pressure between first and second positions. In the first position, the second internal passage is fluidicly coupled with a first annulus surrounding the tubular support. In the second position, the second internal passage is fluidicly isolated from the first annulus. The rupture disc fluidicly isolates the first internal passage from a second annulus surrounding the tubular support and is adapted to rupture, whereby the first internal passage and the second annulus are fluidicly coupled. The expansion cone is disposed in the second annulus and moveable under pressure from fluid in the second annulus.
