Heavy Weight Drill Pipe
Grant Prideco offers three types of Heavyweight Drill Pipe (HWDP). Designed to provide a gradual transition between drill pipe and drill collars, HWDP improves the fatigue resistance of the drill string.
- Standard HWDP is suited for most applications including vertical,extended reach and horizontal wells.
- Grant Prideco’s Tri-Spiral™ HWDP is suited for applications requiring additional hole-cleaning and buckling resistance.
- Spiral-Wate™ HWDP reduces differential sticking, minimizes wear and improves circulation in especially tough drilling environments.
