Product Description

Product Description

Heavy Weight Drill Pipe (HWDP)

Heavy Weight Drill Pipe (HWDP) is an intermediate weight drill stem component
which is used in conjunction with the drill pipes and drill l collars. JX Petro 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. 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.
