| 20080236230 | Hydroforming Method and Apparatus - A hydroforming method and apparatus. | 10-02-2008 |
| 20080257542 | Low Carbon Steel Expandable Tubular - A low carbon steel expandable tubular ( | 10-23-2008 |
| 20090001721 | Protective sleeve for threaded connections for expandable liner hanger - A tubular sleeve is coupled to and overlaps the threaded connection between a pair of adjacent tubular members. | 01-01-2009 |
| 20090013516 | Methods for Expanding a Pipeline - A method of repairing a damaged portion of an underground pipeline positioned within a subterranean formation below the surface of the earth and having a flowbore. In some embodiments, the method includes inserting one or more pipe sections into the flowbore, the one or more pipe sections coupled and forming a throughpassage, positioning the one or more pipe sections within a damaged portion of the pipeline, disposing an expansion device within the throughpassage, and displacing the expansion device along the throughpassage, wherein the one or more pipe sections are radially expanded into engagement with at least the damaged portion of the pipeline. | 01-15-2009 |
| 20090193871 | RADIAL EXPANSION SYSTEM - A radial expansion system. | 08-06-2009 |
| 20090205839 | EXPANDABLE CONNECTION - An expandable tubular liner includes a first tube, a second tube, a mechanical coupling for coupling the first and second tubes, and an insert coupled to the mechanical coupling. The insert is capable of forming a metallurgical bond with at least one of the tubes when energy is injected into the insert. | 08-20-2009 |
| 20100024348 | METHOD OF EXPANSION - A method of expansion. | 02-04-2010 |
| 20100101072 | Apparatus for Radially Expanding and Plastically Deforming a Tubular Member - An apparatus for radially expanding and plastically deforming a tubular member includes a support member with a fluid passage. A mandrel is movably coupled to the support member and includes an expansion cone operable to radially expand and plastically deform the tubular member when moved relative to the tubular member. A pressure chamber is positioned between the support member and the mandrel, and the pressure chamber is fluidicly coupled to the fluid passage. A releasable support is coupled to the support member and operable to selectively couple the support member to the tubular member. | 04-29-2010 |
| 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 |
