API 11B Alloy Steel Welding Hollow Oilfield Sucker Rods Anti-corrosion Sucker Rod For Oilfield


Products Description:


The steel sucker rod is one of the important equipment of oil field. Sucker Rod bars are manufactured from hot rolled alloy steel. Rod bars are machine straightened and cold drawn to the required size. The rod bar ends are hot forged according to API designed sizes. The rods are then heat treated over the full length. As per requirement of mechanical properties, the rods are normalized and tempered to the specified level or quenched and tempered to the required hardness and strength. Care is taken to achieve metallographic structure with no residual stresses in the rod. A sample specimen is cut from the heat treated material and is tested for ultimate tensile strength, yield strength and elongation. The rod is then again checked for straightness. The forged ends are properly aligned with its body. Rods are cleaned by shot-blasting to remove any scale and oxidation. The forged ends are machined on C.N.C. Lathe machines as per API dimensions and checked with API approved gauges.




1. 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.

2. 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.

3. 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.
