ABSTRACT:
A connector device to provide a primary pressure boundary between a flanged nozzle (18) and a column (20) concentrically disposed therein, including a closure member (26) for compressing a seal ring (22) against the nozzle flange (18). The closure member (26) includes a hub portion (34) defining an annular space (36) between the closure member and the column. Graphite gasket rings (40) are inserted into the annular space (36), and drive unit including a sleeve (42) actuator nut (50), and collar (54) is attached to the column at the collar location. Actuation of the nut (50) against the collar (54) draws the column (20) into rigid engagement with the closure member (26), and then advances the drive sleeve (42) along the annular space (36) to compress the gasket ring (40), thereby completing the fluid-tight connection.
