102mm API 3 1/2" Reg DTH Drill Pipes Tubes Rod For Water Well Drilling
Product specifications:
DTH 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 76mm, 89mm,102mm, 114mm, 127mm,140mm 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 API 4 1/2" reg thread or API IF thread, etc.
