Abstract
An expansion system including a mandrel slidably coupled to plurality of primary cone segments that are interleaved with a plurality of secondary cone segments. The expansion system has a the first position wherein the primary cone segments and secondary cone segments are in a retracted position, a second position wherein the primary cone segments are in an expanded position and the secondary cone segments are in a retracted position, and a third position wherein the primary cone segments and the secondary cone segments are in an expanded position. When the expansion assembly is disposed within a tubular member and in the second position, the primary cone segments expand the tubular member into a tri-lobe cross-sectional shape.
