Abstract: An anti-rotation system for use in retaining a threaded connection between a pin and a box. The anti-rotation system includes a key that sets in a recess formed in one of the box or pin. The key is selectively in contact with one of the other of the box or pin, and is activated when the threaded connection begins to decouple. The key is profiled and operates in a cam like fashion to wedge itself between the box and pin when these members begin to decouple and prevents further relative rotation.

Abstract: A broach style anti-rotation device for connected tubular members is described. In embodiments, the broach tool is inserted into a slot in an outer diameter surface of the pin, and teeth of the broach, which have a successively greater height when moving from the front to the tail of the broach, cut a slot in a surface of the box. Sidewalls of the broach and its teeth engage shoulders of each slot to prevent the rotation of the tubular members relative to each other.

Abstract: A computer-implemented method is disclosed for characterizing a threaded coupling such as between two tubular members, e.g., casing segments employed in the field of oil and gas recovery. In one embodiment, a virtual model of the coupling is generated, and the virtual model is re-arranged to simulate plastic deformation of at least part of the coupling. The re-arranged model is analyzed to derive a stress/strain distribution of the coupling subject to subsequent loading, and an SAF (stress amplification factor) is determined from the analysis that reflects the effect of cyclic loading of the coupling. The method facilitates a thorough assessment of the performance of the coupling in fatigue.
