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 

More Drill Pipe Specification:

Available in a variety of lengths, diameters, wall thicknesses, and thread configurations.

Applications

• Underground mining
• Quarry benching operations
• Water well drilling
