3,Avaliable in stocks if not byg quantities

Our 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. As it bends easily, it simplifies directional control and minimizes connection fatigue problems common to high-angle or horizontal drilling. The reduced number of pipe failures and increased drill-stem service also make HWDP appropriate for some straight-hole applications. Various combinations of HWDP, drill collars, and standard drill string can be created to meet the challenge of severe drilling conditions.

We can supply integral HWDP from 2-7/8” to 6-5/8”. Also we can supply friction welded HWDP, which is assembled with AISI 1340 steel pipe and AISI 4145H or 4137H tool joints.
