Sucker Rod Centralizer – Extend Sucker Rod Life and Reduce Friction
Sucker rod centralizer is mainly used in pumping well to centralize sucker rod and reduce the friction between tubing and sucker rod.
Due to the elastic deformation of sucker rod, rod and oil tube wall is easy to produce friction and sucker rod break easily. when rod go up and down inside of the tubing.
Sucker rod centralizer has strong flexibility and larger outer diameter to centralize sucker rod. The centralizer casing has high strength and wear resistant structure, so when contact with oil tube, it can reduce the friction.
