AISI 4145H Heavy Weight Drill Pipe/HWDP products - China

The heavy Weight Drill Pipe (HWDP) was developed to provide a gradual transition from the drill collars to the drill pipe. This HWDP helps to prevent stress concentration at the top of the drill collar. It also allow drilling at higher rpms, reducing torque and differential pressure sticking. The HWDP is intended primarily for directional drilling. API Threading (Drill Pipe) Sharpe EngineeringDrill Pipe; Heavy weight drill pipe (HWDP) Drill Collars; Non-Mags; Subs and Stabilizers; Sharpe has the capability to machine BHA drill string threads from ½ OD to 7 5/8 OD. Sharpe support operators, drilling contractors and oilfield rental companies for batch repairs, third party inspections and re-cuts on used drill pipe threads.


Standard heavy weight drill pipe is friction welded. DP-Master also manufacture heavy weight drill pipe from an integral bar of AISI 4137H / 4145H modified alloy steel, in accordance with API / NS-1 specifications. In addition, DP-Master offers DPM-65MS, DPM-HW90SS and IRP HWDP Grade for use in H2S environment. STANDARD HEAVY WEIGHT DRILL PIPE. Heavy Weight Drill Pipe (HWDP) - OCTGHeavy weight drill pipe (HWDP) is usually run in between the drill collars and the drill pipe in order to prevent fatigue of the drill pipe in the vertical drilling industry. Heavy weight drill pipe is also utilized in the horizontal directional drilling (HDD) industry for added strength in high stress situations.
