Water Well Drilling Pipe

  DTH drill pipes play a significant role in all DTH drilling, regardless type of rock, hole depth or drill rig.   The key features of a high quality DTH tube are durability, accuracy and manageability.     Drill Pipe :  

1.Pipe body : cold draw seamless pipe . so the pipe have the accurate size , good centralizer.  2.Pipe body's material is the same grade as Sandvik. 3.Thread connector :Heat and Nitrogen treatment , so the pipe is more durable and easier to load and unload . 4.Friction welding .

      Standard DTH drill pipe:   Diameter: 76mm, 89mm, 102mm, 114mm, 127mm, 140mm;   Length: 1000mm, 1500mm, 2000mm, 3000mm, 5000mm, 6000mm;   Thread: 2 3/8” API REG, 2 7/8” API REG, 3 1/2” API REG, 4 1/2” API REG,                  2 3/8 API IF, 3 1/2 API IF
