The continuous necessity of deeper waterwells has requested more powerful drilling machines with torque capacity up to 3000 Kg.m. For this reason, it is extremely necessary to employ drill pipes that can withstand very strong torsional stress. Our “Premium” drill pipes present the following features:
- Tool joint in 38NC D4 steel, precision-machined with automatic lathe;
- Pipe in N-80;
- Connection between the tools joint and the pipe made with a special thread followed by circumferential welding;
- Tool joints are induction heat-treated and phosphatized.
