high strength polished sucker rod for oil well
high strength polished sucker rod for oil well
Product DescriptionShengji is the leading manufacturer of coated sucker rod in China,In order to improve the anti-corrosion and wear resistant performance of sucker rod, on the basis of Canada advanced liner tubing technology, Shengji Company developed the anti-corrosion and wear-resistant sucker rod production line. 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.
1. Base on the technology of weatherford.
2. New and used rod all avaibable.
3. Anti-scaling.
4. Anti-corrosion.
