WebThis paper reports that sucker rod strings are devices used to actuate pumps located at the bottom of oil wells. The individual rods are connected together by threaded couplings. Since the couplings have a larger diameter than the rods, they sometimes contact the inside diameter of the tubing during the up and down pumping cycle. Usually, this is not … WebThen the sucker rod or coupling simply fracturesin two. The fracture surfaces of a typical fatigue failure have a fatigue portion, tensile tear portion and final shear tear portion. Fatigue failures are initiated by a multitude number of stress raising conditions.
