            High Strength Long Stroke Corrosion Resistant Polished \u00a0Rod<\/span><\/strong><\/p>\n

            The polished \u00a0rod is made of 20CrMo alloy steel and heat treated by quenching and tempering. Its surface is hardened with induction heating. The rod surface is coated with nickel-based alloy (Ni35) to make the rod body not to scale off and crack, and obtain high resistance to corrosion and wear. The product is used for pumping crude oil in deep wells, large displacement wells, heavy oil wells and high corrosion wells.<\/span><\/p>\n

                  The special purpose hollow sucker rod for progressive cavity (PC) pump has the features of large torque bearing capacity of hollow sucker rod to drive PC pump. Compared with the solid sucker rod with the same weight, the torque bearing capacity of the hollow sucker rod is three times larger than that of the solid sucker rod. The large capacity PC pump is usually fitted with the special purpose hollow sucker rod.<\/span><\/p>\n
