DTH Drill Pipe

DTH drill pipe is a innovative type of drill pipe composed of a rod barrel, a male joint, and a female joint. It is widely used in rock drilling and crushing, anchor drilling, geothermal projects, water well drilling, and other applications. Its primary functions include delivering the down-the-hole hammer to the bottom of the hole, transmitting torque and axial pressure, and supplying compressed air to the DTH hammer through its central bore.

During operation, DTH drill pipes endure complex loads such as impact vibration, torque, and axial pressure, along with abrasive wear caused by rock debris ejected between the hole wall and the pipe surface. Consequently, they must possess high strength, stiffness, and impact toughness.

Typically, DTH drill pipes are used in conjunction with DTH hammers and drill bits in open-pit mining, quarrying, and construction projects. As a critical component of the DTH hammer drilling system, these pipes facilitate powerful impacts to the drill bit. Engineered for extreme conditions, our high-quality DTH drill pipes deliver outstanding performance across diverse rock formations. With unmatched durability and versatility, they represent a revolutionary advancement in the drilling industry.
