Rotating control device with replaceable bowl sleeve

摘要

A rotating control device has a bowl including a central passage configured for having a bearing assembly positioned therein. A bowl sleeve ledge is integral the bowl within the central passage. The bowl sleeve is removably disposed within the central passage. Movement of the bowl sleeve along a length of the central passage is constrained by the bowl sleeve ledge and movement of the bowl sleeve radially with respect to the length of the central passage is constrained by a central passage surface. A sealing device of a first configuration is engaged between an exterior surface of the bowl sleeve and the central passage surface. The bearing assembly has an exterior surface of its outer barrel engaged with the interior surface of the bowl sleeve. A sealing device of a second configuration is engaged between the interior surface of the bowl sleeve and the exterior surface of the outer barrel.
