PROTECTIVE SLEEVE FOR THREADED CONNECTIONS FOR EXPANDABLE LINER HANGER

摘要

A method of radially expanding and plastically deforming a first tubular member and a second tubular member, comprising: inserting an end of a tubular sleeve having an external flange into a threaded end of the first tubular member until an end face of the external flange abuts the threaded end of the first tubular member; inserting the other end of the tubular sleeve into a threaded end of a second tubular member; threadably coupling the threaded ends of the first and second tubular member within the tubular sleeve until both the first and second tubular members abut end faces of the external flange of the tubular sleeve; and displacing an expansion device through the interiors of the first and second tubular members to radially expand and plastically deform the threaded ends of the first and second tubular members.
