Abstract

See full text

An expander, preferably for use in expanding a host pipe to be refurbished. A floating pad is disposed to be displaced relative to a chassis by at least one retractable and extendable piston such that the expander has a first expansion range between fully-retracted and fully-extended states. A floating pad jacket and a chassis jacket are disposed to be removably attached to the floating pad and chassis, 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, and 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. At least one piston may be configured to be extended and retracted independently.
