Well-known sucker rod centralizer is a common equipment in the oil field, it is set in the external benchmarking can protect the tube wall, free activities and plays a role of guide is up and down, and stability of a device that is mainly composed of the anchorage rod and centralizer. Sucker rod centralizer by abrasion resistance, heat resistance, impact resistance of polymer engineering plastics injection molding with high strength, impact resistance, wear resistance, long service life etc.

One prominent feature of the sucker rod centralizer is with the centralizer pipe friction coefficient is small, can prevent the anchorage rod eccentric wear, and avoiding the wear between sucker rod and tubing in the dual function, can be called versatile oil field, played an important role in the oilfield. Sucker rod centralizer with double gap between tubing at about 6 mm, thus greatly extend the operation time of pumping well.

Sucker rod centralizer connection on the sucker rod have very good centering effect, to solve the serious problems in the oil field oil well eccentric wear, at the same time can also play a role paraffin, can greatly prolong the service life of the tube, rod, pump, effectively prolong pump inspection cycle played both increase oil production and reduce the production cost is a kind of ideal eccentric wear proof products.
