Key Features

Upset Drill Pipe

- One-piece forging: No welds at the pipe ends, integrally upset thickened.
- Higher strength: Enhanced torsional & tensile resistance, less breakage.
- Better fatigue resistance: Stable sealing, suitable for deep & high-pressure wells.
- Reliable performance: Ideal for heavy-duty, high-torque drilling.

Friction Welded Drill Pipe

- Friction welding process: Joints welded at high temperature, high weld strength.
- Cost-effective: Efficient production, lower cost, wide specifications.
- Stable strength: Weld zone close to base metal performance.
- General application: Suitable for conventional, directional & horizontal wells.
