Dimensions & Surface Properties
Performance Data
Surface Quality & Seal Life
-
All rods manufactured and tested to API Spec 11B — full dimensional, mechanical and non-destructive examination compliance on every batch.
-
Full-length magnetic particle inspection (MPI) on all rods — detects surface and near-surface discontinuities before field deployment.
-
Upset forging on pin ends — increases cross-sectional area at the highest stress concentration zone, extending fatigue life significantly.
-
Grade K rods feature nickel-molybdenum alloy steel for superior resistance to sulfide stress cracking (SSC) in H₂S-rich environments.
-
Grade HL engineered for deep, deviated and high-stroke applications — higher minimum yield delivers more load capacity with the same rod diameter
-
Heat and melt traceability — every rod shipped with full material certification, mechanical test results and NDE reports for well record documentation
-
Standard API pin and box connections — wrench-tight assembly compatible with all major rod guides, centralizers and downhole pump configurations
-
Pony rods available in 2 ft, 4 ft, 6 ft, 8 ft and 10 ft lengths — for precise string design and space-out optimization at any pump setting depth
Engineering highlights
Carbon steel. Ideal for shallow, low-load wells with standard fluid conditions.
62 – 90 ksi yield
Grade C
API 11B steel grades
90 – 115 ksi yield
Alloy steel. Most widely used — high fatigue resistance for medium to deep wells.
Grade D
Most popular
90 – 115 ksi yield
Nickel-molybdenum alloy. Superior corrosion resistance for H₂S and CO₂ environments.
Grade K
115 ksi+ yield
High-strength alloy. Engineered for deep, high-load and deviated well conditions.
