Quality Standards

Manufactured to meet API Specification 11B (latest edition) and AISI Steel Products Manual standards, ensuring reliability and performance in critical applications.

Advanced Manufacturing Process

Each rod is precision-engineered from high-quality 30 CrMoA alloy steel and undergoes controlled heat treatment through quenching and tempering processes. The surface is metal sprayed with nickel-based alloy (Ni35) to enhance corrosion and wear resistance for extended service life in harsh environments.

Our polished rods feature cold-formed, fully rolled threads that provide superior strength and fatigue resistance. The cold-forming process reshapes steel fibers to follow the thread contour, creating thread surfaces with improved corrosion resistance and reduced abrasion within the thread profile.

The work-hardened flank delivers increased surface tensile, yield, and shear strength. Pressure deformation during manufacturing creates a residual compressive stress system at the thread root, effectively counteracting tensile loading. This results in significantly enhanced load capacity, corrosion resistance, and fatigue performance compared to cut or burnished threads.

Applications

Primary connection between pumping units and rod strings in oil wells
Standard grade D polished rods for non-corrosive environments
End upsetting polished rods for combination with sucker rods
Corrosion-resistant models for deep wells, large displacement wells, thickened oil wells, and high corrosion environments
