Heavy weight drill pipe

Heavy Weight Drill Pipe (HWDP) is an intermediate weight drill stem component which is used in conjunction with the drill

pipes and drill collars. Our HWDP is available in standard, spiral and nonmagnetic designs. In some applications,

heavy-weight drill pipes also can be used instead of the drill collars. Our HWDP is made from one-piece AISI

4145H modified quenched and tempered steel. It is designed for tough drilling environment in vertical and directional wells.Our HWDP is a transition member between drill collar and drill pipe. For directional holes HWDP provides weighton-

bit and additional stiffness to prevent buckling.
