| API thread drill pipe rod matched-up with a high-air pressure drill rig, we are doing pretty well |
| 1. Standard API thread forming and orientating processed at one step, which is our technical highlight |
| 2. Hardness and wear-resistance combined alloy steel, supplied by national top-level special steel manufacturer (pipe thickness and material can be user's choice) |
| 3. Not all friction welding is strong, after a specialized friction welding process, welding outcome can be ensured |
| 4. Pipe curvature correction is a must process for each drill pipe |
| 5. Each processing step is stringently controlled, all RARCs are CNC machined |
| 6. Premium alloy steel made joints strictly controlled heat treatment process and standard API thread processing technology, we pay high-attention to all these easily ignored details to ensure pipe stability and thread durability |
DTH Down The Hole Mining Drill Pipe
Down the hole drill pipes play a significant role in all DTH drilling, regardless of application, rock type, hole depth or drill rig
Key features of a high-quality DTH tube are durability, accuracy and manageability
Wooke DTH drill pipes are made of superior alloy and both thread ends are friction welded to the seamless steel pipe
High-pressure air is delivered to DTH hammer by DTH drill pipe, simultaneously it transfers the rotation and press force to the DTH hammer
