DTH drill pipes play a significant role in all DTH drilling, regardless type of rock, hole depth or drill rig.DTH drill pipe is
mainly used in the drilling blasting hole, guardrail hole, mountain reinfrcement, anchoring and other engineering holes in
mines,quarris, high ways, railways and so on.
Feature:
1.Pipe body : cold draw seamless pipe . so the pipe have the accurate size , good centralizer.
2.Thread connector :Heat and Nitrogen treatment , so the pipe is more durable and easier to load and unload .
3.Friction welding .

Advantages of friction welding drill pipe:
1) The optimal combination of drill pipe is realized, the rod body and joint can be made of different materials, and the heat treatment optimization performance is improved.Other forms of drill pipe cannot be achieved.
2) The joint has high mechanical properties and abrasion resistance.Longer service life than other types of drill pipe.
3) Light weight and good flexibility.
4) The drilling fluid channel inside the drill pipe can be designed.The design of the inner hole channel of the threaded probe can fully consider to reduce the hydraulic loss when passing, especially to reduce the loss caused by the threaded joint part, can improve the working efficiency of the drilling fluid system.
5) With the improvement of welding equipment, welding process and technology and the improvement of heat treatment technology, the connection strength of friction welding is higher than that of the base material itself.The welding strength of the weld is higher than that of the base material.
6) Conduct integral tempering and heat treatment on the pier of friction welding drill pipe after it is thick, and its bending resistance and flexibility are greatly improved.
