Abstract

Casing head device connects casino pipe within conductor pipe, transferring load from former to later. The device includes a casing head resting on the casing pipe, with slip connectors to grip the casing pipe. A base plate below the casing head rests on the conductor pipe, and connects to the casing head with threaded stud members. A retainer ring between the casing head and base plate connects/contacts the slip connectors such that upward movement of the retainer ring engages the slip connectors into a gripping mode. The retainer ring is adapted to slide up and down on threaded stud members. Upper and a lower nuts on the threaded stud members function such that tightening the upper nuts against the retainer ring pushes the retainer ring upwardly to engage the slip connectors into gripping mode, while downward tightening the lower nuts against the base plate transfers load.
