Description
API 5DP Heavy Weight Drill Pipe (HWDP) For oil gas drilling
Integral Spiral HWDP is to extend the central upsets of heavy weight drill pipe and to cut spiral.
groove on HWDP.
This 5-1/2″ integral heavy weight drill pipe (HWDP) is forged from a solid piece of 4145H alloy structural steel. With no welded zones, it provides excellent fatigue resistance for high-torque and directional drilling applications.
