    • 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.
    • 一种用于径向膨胀并使管状构件塑性变形的装置。 在一些实施例中,该装置包括管状支撑件,滑动套筒,破裂盘和膨胀锥体。 管状支撑件具有第一内部通道,其中设置滑动套筒,以及流动通道,其中破裂盘就位。 滑动套筒具有第二内部通道,并且可以通过第一和第二位置之间的流体压力来移动。 在第一位置,第二内部通道与围绕管状支撑件的第一环形件流体联接。 在第二位置,第二内部通道与第一环形件流体隔离。 破裂盘将第一内部通道与围绕管状支撑件的第二环带流体隔离,并且适于破裂,由此第一内部通道和第二环空间被流体连接。 膨胀锥体设置在第二环形空间中,并且在第二环形空间中的流体的压力下可移动。
