Drill Pipe Description
In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.
Drill Pipe Features:
Friction welded
• Friction welding gives much stronger joints compared with electrode welding due to less risk of impure joints.
Competitive Advantage
High strength chromium-molybdenum steel with high fatigue strength and excellent wear resistance
