Paper: Effect of Organic Corrosion Inhibitors on Corrosion Fatigue

Subsurface equipment such as sucker rods and pump parts are subjected to the combined action of cyclic service loads and corrosive fluids simultaneously, often causing failure due to corrosion fatigue. Organic inhibitors are widely used to prevent failure resulting from corrosion fatigue. There is, however, little or no data to show the nature and the extent of the effects they produce on the course of corrosion fatigue per se. This investigation deals with some of the variables that affect the corrosion fatigue performance of carbon steels in the presence of organic inhibitors.
