An apparatus and method of using an apparatus for refacing a tubular connection is provided. In one example, the apparatus has a mandrel connectable to a threaded portion of a tubular connection and two face plates bearing cutters for refacing the torque-stop surface and primary surface of the tubular connection. The cutting is controlled by an engaging nut moving along a threaded portion of a drive shaft, and the two face plates may be spaced apart at a fixed distance in order to maintain the distance between the torque-stop surface and the primary surface after refacing. The apparatus uses a locking pin to assist in tightening or loosening the mandrel into place using the remainder of the apparatus. An air-oil system is provided to supply air and oil to the cutting surfaces as the apparatus refaces the connection. An exemplary pin refacer and an exemplary box refacer are both disclosed. |
