About NOV Grant Heavy Weight Drill Pipe

NOV 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.

NOV Grant Prideco’s Tri-Spiral™ HWDP is suited for applications requiringadditional hole-cleaning and buckling resistance.

Spiral-Wate® HWDP reduces differential sticking, minimizes wear and improves circulation in especially tough drilling environments.
