Product details

Rock drilling tools manufacturer Prodrill™, DTH Drill Pipes

The downhole drill pipe products are made of high-quality materials,the heat treatment of the materials is carried out by an integrated multi-functional furnace,all threads are processed by professional numerical control,the internal part of the end of the rod body is thickened,the strength of the weld joint is greatly improved,and the tempering treatment is carried out after friction welding,so that the quality of the drill pipe is stable and reliable,and the service life is greatly prolonged.

DTH drill tubes are used for connecting DTH hammer and DTH button bits rock drill bits, they are made from seamless tubes. Tubes 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.

ALL DTH drill tubes are friction welded, and usually the threads are standard API connections, like 2 3/8" API REG thread, 3 1/2" API REG thread or API IF thread, etc. According to customers request, from 1000mm to 5000mm length of tubes, O.D we can offer 50mm, 60mm, 76mm, 89mm,102mm，127mm，140mm.
