Abstract
Tubing string rotators, safety rod clamps, combination tubing string rotators and safety rod claims, and rotating split tubing hangers are provided. The tubing string rotator can rotate a tubing string suspended in a hydrocarbon well from a rotatable support mandrel. The support mandrel can be positioned at the well head and can be supported against downward axial movement. The tubing string rotator can comprise a motor for producing a rotational force, a drive assembly for applying the rotational force to drive the rotation of the support mandrel, and a controller operatively connected to the motor for intermittently activating the motor, causing rotation of the support mandrel, for selected intervals of time, followed by selected intervals of time of motor inactivation, in which no rotation of the support mandrel occurs. Intermittently or non-continuously rotation of the tubing string can result in more even wear and/or erosion of the tubing string.
