Abstract

See full text

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.
