Patent attributes
A mudline connector including a compression adaptor which can be elastically deformed onto an internal tubular member. The compression adaptor deflects inwardly to grip upper and lower sealing mandrels, providing axial and bending load support and creating a seal to isolate bore pressure from an outer annulus. The clamping arrangement provides a sealed connection between two well casing sections extending in opposite axial directions. The well casings are gripped and held in an end to end configuration by a radial load applied internally by a compression ring. The connector is activated by introducing pressure to activate pistons which in turn provide an axial thrust to stroke the internally tapered compression ring along the externally tapered compression collar, effectively creating an interference fit therebetween. This deflects the inner surface of the compression collar inwardly, deflecting the compression adaptor inwardly to grip the outer surfaces of the upper and lower sealing mandrels.
