Polished Rod

The polished rod is made of high-quality alloy steel, with high tensile strength, smooth surface and long service life. All polished rods are produced in accordance with API Spec 11B. The polished rod is designed to connect the sucker rod string to the beam pumping unit through polished rod packing. The rod is a circular cross-section rod. We provide three types of polished rods: ordinary polished rods, polished rods-metal spraying and single-ended upset polished rods.

Features

• High tensile strength.

• Polished rods are mainly used for the connection of pumping units and rod strings in oil wells.

• Ordinary D grade polished rods are not suitable for highly corrosive environments.

• Corrosion-resistant polished rods are used to pump crude oil in deep wells, large displacement wells, heavy oil wells and highly corrosive wells.

• Can be used with sucker rods and hollow sucker rods.

• Solid and hollow structure to meet different requirements.
