With the increase of working time, conventional sucker rods are prone to corrosion and eccentric wear during operation, and are not suitable for harsh working conditions. In 2012, Sunrise Petro developed a fully coated sucker rod. By using HDPE resin to fully coat the sucker rod body, the anti-corrosion and anti-abrasion of the sucker rod is realized. And this tech of Sunrise Petro has gained patent in China, Canada and the United States.
ShengjiPetro 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, ShengjiPetro Company developed the HDPE coated sucker rod production line. It is the ideal matching products of liner tubing. For the oil well that uses the ordinary tubing, we add the centralizer on the sucker rod body to improve the service life of sucker rod and tubing. The coated layer is on the surface of the rod. Overall coated polymer material is the most effective anti-corrosion and wear-resistant technology. Smooth surface and low friction coefficient with steel helps to reduce load of pumping unit and it has energy saving effect. ShengjiPetro coated sucker rod already applied for a patent. New and used rods are all available for ShengjiPetro coated tech. Now our annual processing capability is 600,000 joints.
