In the demanding world of DTH drilling, the efficiency of your operations hinges on the quality of your drill rods. Whether you are engaged in water well drilling, mining, or quarrying, the drill pipe acts as the critical lifeline, transmitting massive torque and thrust from the rotary head to the hammer. At Yanggu Henglong, we engineered our 76mm DTH drill pipes to excel where standard pipes fail.
Not all steel is created equal. While many competitors use standard carbon steel, Henglong's DTH drill tubes are manufactured using superior 23CrNi3Mo alloy steel.

As a leading manufacturer, we offer a full range of diameters — from 50mm to 159mm — to match any drill rig configuration. We don't just sell hardware; we provide durability, accuracy, and manageability. Our rigorous QC process ensures that every pipe leaving our factory can withstand the harshest rock types and deepest holes.
