20110000682 | Method and Apparatus for Making Up and Breaking Out Threaded Tubular Connections - An internally gripping tong to rotate tubular segments comprising a central cam body rotatably disposed within a housing having a plurality of windows. The cam body is surrounded by a plurality of angularly distributed gripping jaws slidably received within the windows. The tong is disposed within a bore of a tubular segment, and rotation of the housing relative to the cam body deploys the gripping jaws radially outwardly within the windows to engage the interior wall of the tubular segment. The tong may be self-energizing in both the make-up and the break-out modes of operation. The tong may be deployed to grip the tubular segment using a device to frictionally couple the housing to the tubular segment that cooperates with the top drive assembly, or by an internal actuator that imparts rotation to the housing relative to the cam body. | 01-06-2011 |
20100116558 | Method of Running a Pipe String Having an Outer Diameter Transition - One embodiment provides an adjustable guide | 05-13-2010 |
20090126536 | Slippage Sensor and Method of Operating an Integrated Power Tong and Back-Up Tong - Method and apparatus to make-up or break-out a threaded tubular connection using an integrated power tong and back-up tong ( | 05-21-2009 |
20090065223 | Sprag Tool for Torquing Pipe Connections - A pipe torquing sprag tool comprises one or more elastomeric sprags supported on a sprag support in an arrangement lying generally in a plane that is generally perpendicular to the axis of the rotatable sprag support. Each sprag has a solid, uninterrupted side and an interrupted side, and each sprag reacts to a lateral force in the general direction tangential to the surface of the sprag support and applied near the top of the sprag to bend the elastomeric sprag either toward the interrupted side to at least partially lean, fold or collapse, or towards the substantially uninterrupted side for being deformed to a generally compressed and non-compliant configuration for gripping. The sprag tool of the present invention may comprise a sprag support for positioning an external arrangement of sprags for being inserted into the bore of an add-on pipe segment. Alternately, the sprag tool of the present invention may comprise a sprag support for positioning an internal arrangement of sprags for being received over the end of an add-on pipe segment. | 03-12-2009 |
20090057032 | Segmented Bottom Guide for String Elevator Assembly - The present invention is directed to a segmented bottom guide for directing the top of a tubular member into and through a bore in the bottom of a tapered bowl so that the tubular member can be engaged by pipe slips. One embodiment of the segmented bottom guide of the present invention comprises a bottom guide retainer having a plurality of chambers for being disposed intermediate the top of a bell guide and the bottom of the tapered bowl. The bottom guide segments are radially received into, and securable in, the retainer to therein and together form a generally conical frustum generally aligned with and intermediate the top of the bell guide and the opening of the tapered bowl. | 03-05-2009 |

20090014169 | SINGLE JOINT ELEVATOR WITH JAWS SECURED BY A POWERED DOOR - A single joint elevator for releasably securing a tubular segment for hoisting the tubular segment into position to be threadably coupled to a pipe string suspended in a borehole. The elevator comprises two pivotally coupled jaw retainers securing jaws for engaging and gripping the tubular segment. A powered door is pivotally coupled to a first jaw retainer for selectively securing the second jaw retainer. The powered door includes a pivotable collar, a linear actuator assembly, and a linkage mechanism for selectively closing the door and clamping the distal end of the second jaw retainer to the distal end of the first jaw retainer. The actuator assembly clamps the jaw retainers with sufficient force for the jaws to grip and support the tubular segment for lifting. | 01-15-2009 |
20080277108 | SINGLE JOINT ELEVATOR WITH GRIPPING JAWS - Single joint elevator and method for releasably securing a tabular segment. A generally horseshoe-shaped body has a slot for receiving a tubular segment, and an actuator assembly that selectively moves opposing jaws from a removed position to a deployed position to grip and retain the tubular segment within the slot of the body while hoisting the body. The deployable jaws are either rotatably or translatably moved from the removed position to the deployed position and may be pneumatically, hydraulically, and/or electrically actuated. The actuator assembly may include wedges operatively coupled to actuators for selectively biasing the wedges against the jaws, or a cam ring rotationally coupled to the body and rotated by an actuator coupled between the body and the cam ring, wherein the cam ring has an inner cam surface for inwardly biasing the opposing jaws. | 11-13-2008 |
