Sucker Rod Introduction:
This product is mainly used in oil well with serious corrosion and eccentric wear problem. It is the ideal matching products of liner tubing. To the oil well that use the ordinary tubing, we add the centralizer on the rod body to improve the service life of sucker rod and tubing. The cladding layer is on the surface of the rod. New and used rod all avaibable. Overall coated polymer materials is the most effective anticorrosion and wear-resistant technology. Smooth surface, low friction coefficient with steel, it helps to reduce load of pumping unit and it has energy saving effect. Shengji coated sucker rod already applied for a patent.
