Claim 17:
18. An expander, comprising:
a chassis;
a floating pad, the floating pad disposed to be displaced relative to the chassis by at least one retractable and extendable piston, such that retraction and extension of the at least one piston is configured to transition the expander between a fully-retracted state and a fully-extended state, wherein the expander has a first expansion range between the fully-retracted state and the fully-extended state;
a first cone positioned at a first end of the chassis and a second cone positioned at a second end of the chassis;
a floating pad jacket disposed to be removably attached to the floating pad, such that the floating pad jacket increases the first expansion range of the expander to a second expansion range when the floating pad jacket is attached to the floating pad;
a chassis jacket disposed to be removably attached to the chassis, such that the chassis jacket increases the first expansion range of the expander to a third expansion range when the chassis jacket is attached to the chassis; and
first and second cone jackets each disposed to be removably attached to the first and second cones respectively;
wherein an exterior surface of the expander is substantially continuous when: (1) the floating pad jacket, the chassis jacket and the first and second cone jackets are all attached to the floating pad, chassis and first and second cones respectively, and (2) the expander is in the fully-retracted state.
