API 11B Oilfield Hollow Sucker Rod With Sucker Rod Centralizer Polished Steel Pony Rod With Centralizer

Products Descriptions:

Polished rods are manufactured from hot rolled alloy steel bars like AISI 4142, AISI4XX, Chrome-Moly Alloy (20CrMo or 30CrMo) . Bar and sucker rod dimensions and tolerances conform to API Spec 11B, latest edition. All bars are straightened and Eddy Current inspected for surface defects. Both ends are upset by automated high speed hot forging. Bars are full length normalized to relive residual stresses, air-quenched, and tempered to refine and homogenize grain structure, and surface shot-cleaned to remove any remaining heat treat scale.

We also provide the rod accessories like polish rods, sinker bars, rod couplings, pony rods.
