Supplier's note

  1. Technical Breakthroughs:

    • Forged Alloy Steel: Triple-hardened material ensures 20% higher fatigue resistance than standard steel.
    • Precision Thread Design: NC38 threading reduces slippage by 40% in high-torque scenarios.
    • Slick Coating: Reduces friction by 25% compared to uncoated collars, extending tool life.

  2. Version Selection Guide:

    • Base Model: Ideal for standard oilfield drilling with moderate depth requirements.
    • Advanced Model: Choose for abrasive formations where enhanced corrosion resistance and tighter tolerances are critical.
    • Pro Model: Best suited for ultra-deep drilling or high-pressure environments, offering unmatched tensile strength and precision.

With the Pro Model’s 156,000 psi tensile strength, operators can safely drill through ultra-hard rock formations. Paired with its ±0.0005" thread precision, this ensures seamless integration with advanced drilling systems, minimizing downtime and maximizing operational efficiency.
