Heavy Weight Drill Pipe

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