摘要： 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. Following make-up of the joint, first sealing surfaces of the pin and box mate to form an internal metal-to-metal seal, and 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.

摘要： 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.
摘要翻译：用于特别在OCTG（油国家管状物品）领域中使用的用于连接管的螺纹接头，例如在钻井时在气体或油生产中和/或壳体中的管道可以包括具有端面的销和联接器或盒当接头组成时，不要面对销的任何表面。销可以在销螺纹部分的远侧的第一密封表面和靠近销螺纹部分的第二密封表面之间具有销螺纹部分。联接器或箱体可以在第一密封表面和靠近盒螺纹表面定位的邻接肩部之间具有盒形螺纹表面，以及位于盒螺纹表面的远侧的第二密封表面。在接头构成之后，销和箱的第一密封表面配合以形成内部金属对金属密封，并且销和箱的第二密封表面配合以形成外部金属对金属密封其中内部和外部密封件由一个环形表面和一个截头圆锥形表面之间的接触限定。

摘要： A threaded joint includes a first seal ring having a tapered shape in a cross section on an axial plane, this ring having an L-shaped metal reinforcement ring embedded in it. The threaded joint can also include a second seal ring positioned more internal to the first seal ring and located in a housing between the end of a threaded section and the nose of the box. The second seal ring has a first base, a second base axially opposite to the first base, and protruding annular ribs either on the external surface or on an internal surface.

摘要： Thin-walled pipe joints can include 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.
