Abstract
A box end casing connector is disclosed for use in connecting a string of casing sections for use in oil and gas drilling operations. The box connector is provided with an inside surface conventionally threaded with API standard threads and adapted to receive a pin member with mating threads. The pin member utilized is the threaded end of a subsequent casing section. The box connector is adapted to be integrally welded to the casing section and is further provided with a tapered shoulder and an externally beveled face to facilitate movement of the casing connector into and out of the bore of a restricted diameter blowout preventer.
