Abstract
A rotating control device is disclosed for the use of oil, gas or geothermal wells. While providing for sealing with or without rotation of the drill pipe, the device consists of a housing with guide rails attached beneath the two part dual actuated clamp that can be locked in place by remote controlled retention pins. The design has a novel adapter design enabling a common RCD bearing assembly to be installed in a variety of different housing sizes.
