Product Description

Drill pipes used in applications such as DTH/DTHR/DR comprise a steel pipe with a pin at one end and a box on the other. These pipes transmit rotational torque and thrust from the drill rig rotary head to down hole drilling tools. Geological conditions significantly affect drill rod selection, with varying requirements for strength, wear resistance, and corrosion resistance in different formations.

Application Areas

Water conservancy engineering: Drilling various water wells including agricultural irrigation, urban water supply, and industrial water wells
Geological exploration: Drilling geological samples to understand underground structures and rock distribution
Mining: Drilling and excavation work in mines including water exploration, gas exploration, and tunnel exploration
Construction engineering: Pile foundation drilling and underground continuous wall construction for building foundations

Selection Guide

Soft strata (clay, sandy soil): Medium strength drill pipes (DZ50 material) with focus on flexibility and smooth medium conveyance
Hard strata (rocks, gravel layers): High-strength materials (R780) with thickened joints for bending and fatigue resistance
Complex strata (underground water, salt layers, caves): Corrosion-resistant treated drill pipes with higher toughness for sudden force conditions
