DTH drill pipe is made of high-quality alloy steel, and the seamless steel pipes at both ends are connected by friction welding. During operation, high-pressure air is delivered to the DTH hammer through the DTH drill rod, while the rotation and pressure are transmitted to the DTH hammer. The key features of high-quality DTH drill pipe are durability, accuracy and manageability.

Down the hole DTH drilling pipe is mainly used for rock drilling and crushing, anchor drilling, geothermal air conditioning drilling holes, water well drilling etc. The pipe body is made of materials produced by well-known large-scale steel enterprises in China. The inner thickening process is adopted at both ends of the pipe body. After friction welding, it is tempered. The DTH drill pipe joint is quenched and tempered after rough machining, and the surface is nitrided after fine machining, which effectively eliminates the failure probability of sticking, breaking, and outer diameter expansion. It is more wear-resistant and easy to disassemble. All precision imported CNC lathes and customized forming knives are used for thread processing. All threads are equipped with thread gauges that meet international standards. Therefore, the quality of our DTH drill pipe is stable and reliable, and the service life is greatly extended. DTH drill pipe plays an important role in the entire DTH drilling operations (regardless of application, rock types, drilling depth or drilling rigs).
