High Strength Oil Well Drilling Tools API 11B Polished Pony Oilfield Sucker Rods
Oil Production API 11B Sucker Rod, Polished Rod, Pony Rod, Oil Well Drilling Tools
A steel sucker rod is one of the important equipment of oil field. We can provide seven kinds of the level of sucker rod, including C, K, D, designed and manufactured as per API Spec 11B.
C grade sucker rod series - is mainly used for light, medium load, no corrosion or corrosion shallow Wells or in deep well pumping, material is carbon steel or manganese steel.
Grade D sucker rod is made of high quality alloy steel, after heat treatment with high strength, plasticity is good, long life and other characteristics, it is suitable for light when there is no corrosion or corrosive medium in the deep Wells under the environment of use.
K level of sucker rod with different content of Ni Cr - Ni - Mo high quality alloy steel manufacturing, have anticorrosive, resistance to corrosion function, respectively applicable to strong corrosion of shallow, middle and deep Wells.
