CROWN CR50 CR60 Wireline Core Dth Drill Rod Extension Connecting Rod Drill

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • DTH Drilling Efficiency: Designed for down-the-hole (DTH) drilling operations, enabling high-performance rock fragmentation and core extraction in hard formations.
  • Secure Connection System: Hexagonal ends ensure stable stacking, leak-proof connections, and resistance to shifting during high-pressure drilling tasks.

Key features

  • 1. Material Technology

    • With forged carbon steel construction, ensure exceptional durability and resistance to wear in heavy-duty drilling operations. The material’s strength is ~30% higher than cast steel alternatives*, enabling prolonged use in abrasive mining environments.

  • 2. Interactive Design

    • The hexagonal end design allows secure, non-slip connections, preventing rotation during drilling. This improves stability compared to round-ended rods, reducing misalignment risks in high-pressure applications.

  • 3. Performance Parameters

    • Engineered for extended reach and compatibility with DTH (down-the-hole) drilling systems, these rods deliver consistent performance across varying rock densities. Their forged structure supports higher torque transmission than standard drill rods*, enhancing drilling efficiency.

  • 4. Scenario Solutions

    • Optimized for mining and construction applications, these rods enable continuous operation in harsh environments. The hexagonal ends and corrosion-resistant steel ensure reliability for deep-core drilling and demanding underground projects.

  • 5. Certification Standards

    • Constructed to meet industrial safety and quality standards for mining equipment, ensuring compliance with global regulations for durability and safety.

Supplier's note

  1. Technical Breakthroughs:

    • Forged Carbon Steel: 20% stronger than cast steel, enabling safer high-pressure drilling.
    • Hexagonal Ends: Reduce misalignment by 40% compared to cylindrical designs, ensuring stable connections.
    • Passivated Surface: Triple the corrosion resistance of uncoated steel, extending lifespan in marine or chemical environments.

  2. Version Selection Guide:

    • Base Model: Ideal for standard mining and construction projects requiring cost-effective durability.
    • Advanced Model: Suitable for moderate-pressure drilling in corrosive environments (e.g., offshore oil rigs).
    • Pro Model: Designed for extreme applications like deep-earth mining or high-temperature geothermal projects. With its 975 MPa tensile strength, it outperforms industry benchmarks by 25%, ensuring zero failure under peak loads. Pair it with epoxy coatings for added corrosion protection in acidic drilling fluids.
