Abstract
At least one embodiment generally relates to using an installation tool to pass an expansion mandrel through an elongated member to at least locally, radially expand at least a portion of the elongated member and achieve an interference fit with a radially expandable member located about an outer surface of the elongated member. In one embodiment, the elongated member is radially expanded over its entire length and may include a stepped feature so that only a portion of the elongated member achieves the interference fit with the radially expandable member. During the radial-expansion process, both the radially expandable member and the elongated member may be at the same or approximately the same temperature. Before the radial-expansion process, the radially expandable member may be assembled using press-fit techniques, shrink fit techniques, clearance fitting techniques, or combinations thereof.
