20110048741 | DOWNHOLE TELESCOPING TOOL WITH RADIALLY EXPANDABLE MEMBERS - A downhole axial expansion or telescoping tool includes radially expandable tubular members. The tubular members are relatively moveable before and after radial expansion, and include an intermediate layer therebetween of a non-metal or non-cladding material. The intermediate layer may provide any one or more of lubricity, load transfer, sealing, and shape retention during and after radial expansion. | 03-03-2011 |
20100282477 | SLEEVE FOR EXPANDABLE TUBULAR THREADED CONNECTION - A tubular sleeve overlaps the threaded connection between a pair of adjacent tubular members that are to receive an expansion device for radial expansion and plastic deformation of the threaded tubular connection. | 11-11-2010 |
20090038138 | Protective compression and tension sleeves for threaded connections for radially expandable tubular members - A radially expandable multiple tubular member apparatus includes a first tubular member and a second tubular member engaged with the first tubular member forming a joint. A sleeve overlaps and couples the first and second tubular members at the joint. | 02-12-2009 |
