SHOT PEENING

The sucker rods are run through a shot peener that is designed to clean the rods down to bare metal. It is a gravity feed, dual wheel, reflective peener that uses 330 cold chilled shot to clean the rods and peen the surface. Peening the rod puts the surface into compression which corrosion and stress has to penetrate before becoming harmful to the rod. This compression and the cold working process of the surface of the rods increases the life of the rod by reducing the effect of the stress cycles the rod has received.
