Key Specifications/Special Features:
API 3 1/2''Reg down the hole DTH mining drill pipeDown 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. Wooke 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 DTH drill pipe:Diameter: 76mm, 89mm, 102mm, 114mm, 127mm, 140mm,Length: 1000mm, 1500mm, 2000mm, 3000mm, 5000mm, 6000mm;Thread: 2 3/8" API REG, 2 7/8" API REG, 3 1/2" API REG, 4 1/2" API REG, 2 3/8 API IF, 3 1/2 API IFSpecial DTH drill pipe:The drill pipe for Atlas Copco – Ingersol Rand T4, Schramm T64, Atlas Copco F6, L6 and L8, and the drill pipe for Sandvik Driltech D25/D40K.Packaging & shippingMining drill pipes will be packed in bundles, shipped by sea, by air or by land.For further information please kindly us.Â
| 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. |
