Shot Peening of Sucker Rods
Sucker rods are one of the most crucial components in a working oil well, connecting the pump jack at the surface of the well to a down-hole pump. Steel rods are joined by threaded couplings to make a string approximately 5,000 feet long.
The shot peening process relieves the residual stresses built up in the sucker rods from down-hole usage, providing the benefits of increased strength and durability.
Shot peening also helps prevent corrosion of sucker rods when they are in oil wells by placing the outer layer of the rods into compression.
The anchor pattern supplied by shot peening also allows a corrosion inhibitor to attach easily. The role of the inhibitor is to prevent corrosion during storage and everyday use.
