Abstract

An apparatus for radially expanding and plastically deforming a tubular member. In some embodiments, the apparatus includes a support member and an adjustable expansion device coupled thereto. The adjustable expansion device includes a tubular support member with a plurality of circumferentially spaced apart inclined surfaces, a plurality of circumferentially spaced apart expansion segments movably coupled to the tubular support member, and an actuator for displacing the expansion segments relative to the tubular support member to thereby displace each of the expansion segments onto corresponding inclined surfaces.
