Abstract

See full text

Embodiments of the present disclosure relate to apparatus and methods for making up and evaluating tubular threaded connections. A tong assembly may be used for making up threaded connections. A threaded connection may be made up automatically by controlling the rotation speed of the tong assembly according to measurements of torque, turns, and/or time. After a threaded connection is made up, measurements of time, torque, and/or turns may be corrected based on operating parameters. The corrected measurements may be evaluated for indications of failure, such as discontinuity, torque spikes, and torque drops. The threaded connection is then accepted or rejected based on the evaluation.
