ABSTRACT:
An articulated full gauge opening pipe connector is disclosed. The connector apparatus is particularly adapted for use in under sea applications. The apparatus incorporates a ball which has an axial passage therethrough. The passage opens to the full gauge of a pipeline to avoid constricting flows therethrough. The ball is attached at the end of a short connector pipe preferably terminating in a flange. The ball has a spherical external surface. It stabs into a conforming housing which is formed of a first flange which bolts to an elongate sleeve surrounding a pair of seal members preferably formed of hard material such as bronze. The seal members are preferably pressure actuated to bear against the external surface of the ball. The seals circle the ball, locking it in the tubular housing by positioning the seal members on opposing sides of a plane through the center of the sphere. The seal members open to a space enabling the collection of pressure fluid therein for testing purposes. They are preferably spring loaded against the ball. The tubular housing is assembled to the first flange which in turn is adapted to be connected with a connective pipe terminating in a conventional flange.
