Hot Sale API 2 3/8'' REG Standard 76 89 102 Mm Water Well Rock Dth Drill Rod
Product Description
DTH drill pipes are widely used in mines, water wells, geothermal,
petroleum and other types of DTH rigs. High quality carbon steel
ensures the close combination of friction welding process and
joint.according to different application, different diameters of
drill tubes are needed, basically, smaller dth hammers need smaller
dth drill tubes, vice versa. usually we are offering 50mm, 60mm,
76mm, 89mm, 95mm, 102mm, 114mm, 127mm, 140mm, 159mm.If you have
special requirements, please contact us. We have professional and
experienced engineers who understand that some drilling conditions
may require special bit configuration. We can design and
manufacture according to your specific requirements.

Advanced product system
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.
