ABSTRACT:
The present invention is directed to a split locking ring for wellhead components. In one illustrative embodiment, the device comprises a first internally threaded wellhead component, a second wellhead component, at least a portion of which is positioned within an opening in the first wellhead component, and a rotatable split lock ring comprised of at least two externally threaded sections, wherein at least a portion of the sections of the split lock ring are positioned between the first and second wellhead components and rotated to threadingly couple the sections of the split lock ring to the first wellhead component and thereby secure the second wellhead component to the first wellhead component. In one illustrative embodiment, the method comprises positioning at least a portion of a first wellhead component within an opening in a second internally threaded wellhead component, positioning a split lock ring comprised of at least two externally threaded sections proximate the first and second wellhead components, and rotating the sections of the split lock ring to threadingly couple the externally threaded sections to the internally threaded second wellhead component and position at least a portion of the split lock ring sections between the first and second wellhead components, thereby securing the first wellhead component to the second wellhead component.
