SPECIFICALLY FORMULATED FOR MEDIUM DEPTH WELLS AND/OR MODERATE ROD LOADS

The grade KD sucker rod is manufactured from modified UNS G47200 nickel-chromium-molybdenum alloy steel. After normalizing and tempering with specially selected temperatures to maximize impact properties, all rods are shot peened per our own unique standards, developed to significantly improve corrosion and fatigue resistance. Recommended for reciprocating rod lift applications, the grade KD sucker rod is designed to maximize performance and improve runtime in fluids that are effectively inhibited to prevent corrosion. The grade KD sucker rod is suitable for some Progressing Cavity Pumping (PCP) applications with slim hole, high strength couplings.
