Feature DTH drill pipes (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. JCDRILL 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.
Standard API thread forming and orientating processed at one step, which is our technical high light.
Hardness and wear resistance combined alloy steel, supplier by national top level special steel manufacturer.(Pipe thickness and materials can be users’ choice.
Not all friction welding is strong, after a specialized friction welding process, welding outcome can be ensured.
Pipe curvature correction is a must process for each drill pipe.
Each processing step is stringently controller ,all R arcs-are CNC machined.
Premium alloy steel made joints, strictly controlled, heat treatment process and standard API thread processing technology. We pay attention to all these easily ignored details to ensure pipe stability and thread durability.
Applications
• Underground mining • Quarry benching operations • Water well drilling
