89mm DTH Drill Rod with API Reg Thread 2-3/8" for Blast Rock Drilling
Product Introduce
Down the hole drill pipes 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. Sollroc DTH drill pipes are made of superior alloy and the both thread ends are friction welded to the seamless steel pipe. The high pressure air is delivered to DTH hammer by DTH drill pipe, simultaneously it transfers the rotation and press force to the DTH hammer.

Feature
1. it has features of big rigidity, good sealing capacity, flat outer
structure, and low torque and resistance when rotating;
2. Special heat treatment process to ensure that the connecting
thread has sufficient strength and wear resistance;
3. The body of the drill rod and the joint are welded by a friction
welding process, and then the intermediate frequency return is used
to remove the welding stress to ensure the welding strength and the
straightness of the finished drill rod.
4. The drill rod body and joint are made of European and American
high-quality raw materials to ensure the superiority of normal
construction under harsh conditions.
We can also supply DTH drill pipe from diameter 76mm to 140mm.
