Description

Our sucker rods are manufactured from hot rolled alloy steel bars like AISI ***2, AISI4XX, Chrome-Moly Alloy (*0CrMo or *0CrMo) . Bar and sucker rod dimensions and tolerances conform to API Spec *1B, 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. Sucker Rods & Polished Rod Couplings Box by box API type T or spray metal couplings are available in pin sizes 5/8 through 1 1/8 in full size or slim hole diameters. Sub couplings are available for connecting polished rods or tapered rod strings.
