Drill Pipe Schramm Style DTH drill pipes play a significant role in all DTH drilling, regardless of application, rock type, hole depth or drill rig. The key features of a high quality DTH tube are durability, accuracy and manageability.
Description:
Drill Pipe Schramm Style and Schramm T46 Sytle DTH Drill Pipes
DTH drill pipes transmit compressed air, so as to power the hammers to perform drilling works. Roschen Drill DTH drill pipes are made of superior alloy and the both thread ends are friction welded to the seamless steel pipe. The high pressure air is delivered to DTH hammer by DTH drill pipe, simultaneously it transfers the rotation and press force to the DTH hammer.

Advanced Features:
• Complete sizes for the option, suitable for different types of DTH drilling systems;
• The rods are made of cold-drawn steel with high manufacturing precision;
• Thread joint sturdily linked to the rod via friction welding;
• Nitriding process grants the thread joint good hardness, good wear quality and thus long lifespan.
Applications:
Mining, quarrying, water well drilling, geothermal well drilling, foundation piling, etc.
ROSCHEN DTH Pipe Schramm Style is specialized drill pipe designed for down-the-hole (DTH) drilling applications, particularly in geotechnical and geothermal projects.
This type of drill pipe is known for its robust threaded connections, which ensure secure and efficient power transmission from the drill rig to the DTH hammer.
The design minimizes energy loss, allowing for more effective drilling in various ground conditions, including hard rock.
It's used primarily for creating boreholes for:
• Geothermal drilling: Installing ground loops for geothermal heating and cooling systems.
• Geotechnical exploration: Taking soil and rock samples to assess ground stability for construction.
• Water well drilling: Creating wells for residential, agricultural, and industrial use.
• Micro-piling and foundation work: Installing small-diameter piles to support structures.
