Product Description

Product Description

Heavy Weight Drill Pipe (HWDP) is an intermediate weight drill stem component which is used in conjunction with the drill pipes and drill collars. TIANHE HWDP is available in standard, spiral and non- magnetic designs. In some applications, heavy-weight drill pipes also can be used instead of the drill collars.

TIANHE HWDP is made from one-piece AISI 4145H modified quenched and tempered steel. I t is designed for tough drilling environment in vertical and directional wells. TIANHE HWDP is a transition member between drill collar and drill pipe. For directional holes HWDP provides weight- on-bit and additional stiffness to prevent buckling.
