Abstract

An apparatus for expanding tubulars, comprises a body having a longitudinal axis and at least one collet mounted to the body having a thickest portion designed to contact the tubular. The thickest portion is formed having a first tapered surface. A
first cone has a second tapered surface and is biased longitudinally to move the second tapered surface against the first tapered surface.

Claims (10)

1. An apparatus for expanding tubulars, comprising:
a body having a longitudinal axis;
at least one collet mounted to said body having a thickest portion designed to contact the tubular, said thickest portion formed having a first tapered surface; and a first cone having a second tapered surface and biased longitudinally to move said second tapered surface against said first tapered surface.
2. The apparatus of claim 1, further comprising:
a second cone mounted to said body opposite said thickest portion from said fist cone and contacting said thickest portion at a taper angle to promote said bias driving said thickest portion outwardly away from said longitudinal axis.
3. The apparatus of claim 2, wherein:
said second cone is releasably locked to said body by a lock.
4. The apparatus of claim 3, wherein:
said lock is hydraulically released.
5. The apparatus of claim 4 wherein:
said lock comprises a dog held by a sleeve;
said body comprises an internal passage with flow communication to said sleeve to selectively shift said sleeve away from said dog.
6. The apparatus of claim 5, wherein:
said passage comprises a check valve to allow pressure to be built up in said passage for selective shifting of said sleeve while also allowing well fluid pressure to enter said passage for pressure equalization downhole.
7. The apparatus of claim 3, wherein:
said second cone shifts sufficiently when said lock is unlocked so that said first cone is incapable of moving said thickest portion of said collet outwardly in a direction away from said longitudinal axis.
8. The apparatus of any one of claims 1 to 7, wherein:
said bias on said first cone further comprises a plurality of stacked pistons working in tandem for a pressure multiplication effect with each said piston exposed on one side to a high pressure and on the other side to a lower pressure.
9. The apparatus of claim 7 wherein:
said pistons are pressure balanced with respect to wellbore hydrostatic pressure.
