DTH Drilling
| General introduction: |
Drill pipes that are used in applications such as DTH/ DTHR/ DR basically comprise of a steel
tube with a pin at one end and a box on the other. The job of the drill pipe is to transmit rotational torque and thrust from the drill rig rotary head to down hole drilling tools.
DTH drill tubes are used for connecting DTH hammer and DTH button 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. According to different application, different diameters of drill tubes are needed, basically, smaller DTH hammers need smaller DTH drill tubes, vice avers. Usually we are offering 50mm, 60mm, 76mm, 89mm, etc. ALL DTH drill tubes are friction welded, and usually the threads are standard API connections,like23/8" 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 are available.
