76mm DTH Drill Pipe With High Strength Alloy Steel For High Wear Resistance In Tough Rock Formations

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.

• Friction Welding Technology : We utilize advanced friction welding to join the thread ends to the seamless pipe. This creates a bond stronger than the metal itself, drastically reducing the risk of mid-hole breakage.
• Precision Threads : Equipped with 2 3/8" API REG threads (Pin Box), our pipes ensure a leak-proof seal and easy breakout, even after hundreds of hours of high pressure use.

For professionals who demand precision, here are the detailed specs for our best selling model : 

• Outer Diameter : 76mm
• Wall Thickness : 6mm (Heavy duty reinforced)
• Standard Length : 1000mm (Customizable from 1m to 6m)
• Connection : 2 3/8" API REG
• Wrench Flats : 57mm (For easy handling and quick tool changes)

Our DTH drill strings are designed for versatility across multiple industries. They are perfectly compatible with medium and high air pressure hammers used in:

• Geotechnical Construction : Stable performance in unstable soil.
• Open pit Mining : Durable enough for continuous blasting hole operations.
• Water Well Drilling : High flow design for efficient sludge removal.

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.
