Patent number: 9234612Abstract: A threaded joint has a sealing ring radially positioned between a pin and a box and axially positioned on a portion of the pin on an opposite side of the threads of the pin from the nose of the pin. The sealing ring has two protruding annular lips positioned at a skewed angle to the longitudinal axis, two or more radial annular ribs on an external surface, an internal surface, and an at least partly embedded reinforcement ring. When the joint is made up, the sealing ring is in sealing contact with an annular groove of the box by the annular ribs and in sealing contact with the pin by the internal surface. The internal surface of the sealing ring can have a uniform diameter or have radially protruding annular ribs.Type: GrantFiled: June 20, 2008Date of Patent: January 12, 2016Assignee: Tenaris Connections LimitedInventors: Nestor J.

Patent number: 8840152Abstract: 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.
