Our spray metal polished rods are manufactured to meet API Specification 11B (latest edition) and AISI Steel Products Manual standards. These ultra-high tensile strength rods feature long stroke capability and exceptional corrosion resistance, making them ideal for demanding oilfield applications.

Advanced Manufacturing Process

Manufactured from high-quality alloy steel, each rod undergoes precise heat treatment through quenching and tempering processes. The rod surface is metal sprayed with nickel-based alloy (Ni35) to enhance corrosion and wear resistance, ensuring extended service life in harsh environments.

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 a thread surface 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
