Abstract:
1. A slip ring assembly for supporting an expanded inner tubular against an outer tubular, comprising: said inner tubular having an outer surface and defining an inner passage from which expansion increases the dimension of said outer surface; a swage acting in said passage to increase the dimension of said outer surface; said outer tubular having an inner surface surrounding said inner tubular; a generally cylindrical body having upper and lower ends and a longitudinal axis and mounted to said outer surface of said inner tubular to increase in dimension therewith, said body comprising a plurality of elongated members generally aligned with said longitudinal axis and circumferentially spaced apart; connectors to connect adjacent said elongated members to each other at a plurality of spaced apart axial locations; at least one of said connectors break when said body is increased in radial dimension before said body engages said inner surface of said outer tubular to support said inner tubular against said outer tubular.
