Down-the-hole drill pipe is a high-strength steel pipe used for drilling. They are also called drill rods or drill tubes. DTH drill pipes are usually used with DTH hammers and are used in mining, water well drilling, geothermal, petroleum and various DTH drilling rocks.

Key Points of DTH drill pipe

Purpose

The DTH drill pipe serves as a conduit for the drilling fluid (usually air or mud) to reach the hammer at the bottom of the hole. It also provides a path for the rock cuttings to be brought to the surface.

Material

DTH drill pipes are typically made of high-strength alloy steel to withstand the rigors of drilling in challenging geological conditions.

Design

The drill pipe is designed to be durable and withstand the high impact and vibration associated with DTH drilling. It is threaded on both ends to connect with other components of the drill string.

Length and Diameter

The length and diameter of DTH drill pipes can vary based on the specific requirements of the drilling operation. Longer pipes are used for deeper drilling, while larger diameters are employed for larger boreholes.

DTH drilling is known for its efficiency in penetrating hard rock formations, and the design and quality of the drill pipe play a crucial role in the success of such drilling operations. Tongshun provides different sizes of DTH drill stems, no matter you have any questions, please feel free to contact us.
