Supplier's note

  1. Three Technical Breakthroughs:

    • Material Upgrades: The Pro Model’s high-alloy steel offers triple the corrosion resistance of standard carbon steel, enabling safe use in offshore drilling.
    • Thread Precision: Advanced threading reduces friction by 15%, minimizing wear during repeated pipe connections.
    • Thermal Tolerance: The Pro Model’s heat treatment allows sustained operation at 350°C, surpassing industry benchmarks by 50°C.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard onshore drilling with moderate pressure and temperature.
    • Advanced Model: Suitable for corrosive environments (e.g., offshore platforms) needing enhanced durability.
    • Pro Model: Best for extreme deep-sea or high-temperature geothermal projects requiring peak performance.

*Pro Model pressure rating exceeds API 5CT standards by 20%.
