| 20110233926 | THIN-WALLED PIPE JOINT AND METHOD TO COUPLE A FIRST PIPE TO A SECOND PIPE - Pipe joints and methods for connecting a first pipe to a second pipe are provided. The joint includes a first pipe and a second pipe. The first pipe includes a hollow pin member positioned at about an end of the first pipe. The second pipe includes a hollow box member positioned at about an end of the second pipe. The hollow box member is further configured to at least partially surround the pin member of the first pipe. The joint also includes a first ring placed adjacent an end of the hollow pin member and a second ring engaged with the box member. The second ring substantially axially abuts against the first ring and the first ring substantially axially abuts the box member. The second ring further generally extends from the first ring in a direction opposite to the end of the pin member adjacent to the box member. | 09-29-2011 |

| 20080265569 | Threaded Joint for Pipes Provided with Seal - A threaded joint for pipes comprising at least one seal of the metal-metal interference type arranged externally to the female thread. The joint has an extension of the box beyond the seal which produces an elastic tightening band effect on the seal so that excessive interference on the seal is not necessary, thus favouring correct making up. | 10-30-2008 |
| 20090033087 | THREADED CONNECTIONS WITH HIGH AND LOW FRICTION COATINGS - A threaded metallic joint has the thread surface of pin ( | 02-05-2009 |
| 20100181762 | SUPER HIGH TORQUE DOPE-FREE THREADED JOINT - A high torque threaded joint comprising a box member having threads and a pin member having threads ( | 07-22-2010 |
| 20110133449 | THREADED JOINT SEALED TO INTERNAL AND EXTERNAL PRESSURES - A threaded joint for joining tubes used especially in the field of OCTG (Oil Country Tubular Goods), such as pipes in gas or oil production and/or casings when drilling wells can include a pin and a coupling, or box, having an end surface not facing against any surface of the pin when the joint is made-up. The pin can have a pin threaded portion between a first sealing surface distal of the pin threaded portion and a second sealing surface proximate to the pin threaded portion. The coupling or box can have a box threaded surface between a first sealing surface and an abutment shoulder located proximate to the box threaded surface and a second sealing surface distal of the box threaded surface. Following make-up of the joint, the first sealing surfaces of the pin and box mate to form an internal metal-to-metal seal, and the second sealing surfaces of the pin and box mate to form an external metal-to-metal seal, where the internal and external seals are defined by contact between one toroidal surface and one frusto-conical surface. | 06-09-2011 |

| 20120018081 | JOINTS HAVING IMPROVED SEALABILITY, LUBRICATION AND CORROSION RESISTANCE - Embodiments of the present disclosure provide systems and methods for assembly of tubular joints which overcome the drawbacks and limitations of conventional joints. In certain embodiments, the tubular joints may comprise threaded joints used in oil exploration. Joints may be assembled using a combination of a) position control, b) specific production tolerances for thread parameters, and c) coatings applied on threaded areas of the joint. In further embodiments, the tubular joints may have no torque shoulder and/or metal to metal seals. In additional embodiments, the joints may be further assembled and disassembled several times without application of dope or grease and exhibit enhanced sealability. Beneficially, embodiments of the present disclosure may provide high tolerance, precisely assembled joints that provide improved performance (e.g., mechanical performance, sealability, corrosion resistance, lubrication) and reliability over non-premium connections without the expense associated with premium connections. | 01-26-2012 |
