DTH Drill Pipe, API Rock Drills, Drill Rods, Drilling Machine, Drilling Tools & Drilling Rigs

DTH Drill Pipe Overview
Professional-grade drilling component designed for demanding applications including rock drilling, anchor drilling, geothermal well drilling, water well drilling, and underground coal mine operations. Each pipe consists of a rod barrel, male joint, and female joint, offering a complete solution for down-the-hole hammer systems.
Key Functions
  • Delivers the DTH hammer accurately to the bottom of the hole
  • Transmits torque, axial pressure, and impact vibration
  • Supplies compressed air through the center hole to power the DTH hammer
  • Works seamlessly with rotary air supply mechanisms and propulsion systems
Built for Extreme Conditions
DTH drill pipes endure complex loads: impact vibration, torque, axial pressure, and abrasive sandblasting from rock slag discharged between the hole wall and the pipe.
Engineering Features:
  • High strength to resist mechanical stress
  • Excellent stiffness for accurate drilling
  • Superior impact toughness to withstand repeated shocks
Advanced Manufacturing Process
FeatureBenefit
Professional friction weldingHigh welding strength, no weak points
High-precision CNC machiningAccurate thread connection for reliable linking
Vacuum conditioning & heat treatmentEnhanced torque performance & extended service life
Connection & Working Principle
  • Both ends have connecting threads
    • One end connects to rotary air supply mechanism
    • Other end connects to DTH hammer
  • DTH hammer bit is installed at the front end of the hammer
  • During operation:
    • Rotary mechanism rotates the drill string
    • Compressed air flows through the hollow pipe
    • DTH hammer impacts the bit to break rock
    • Air lifts rock cuttings out of the hole
    • Propulsion mechanism advances the whole drilling assembly
Applications
  • Gas drainage (exploitation) drilling in underground coal mines
  • Water exploration holes
  • Grouting holes in stable geological conditions
  • Mining, geological exploration, hydropower projects
  • Both conventional drilling and impact rotary drilling
