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
Feature
Benefit
Professional friction welding
High welding strength, no weak points
High-precision CNC machining
Accurate thread connection for reliable linking
Vacuum conditioning & heat treatment
Enhanced 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
✓ Longer service life - thanks to advanced heat treatment
✓ Precision threads - fast, firm, and leak-proof connections
✓ Reliable for underground and surface operations
