Graphic Details
Heavy Duty Drill Pipe (HWDP) is an intermediate material used in weighing drill string assemblies
Connection with drill pipe and drill collar. HWDP is available in standard, spiral and non-magnetic designs. In some applications, it is heavyweight
Drill pipes can also be used instead of drill collars. HWDP is a one-piece conversion of AISI 4145H into quenched and tempered steel. It is a drilling environment for straight and directional wells designed for toughness.
The HWDP is the transition between the drill collars, as well as the drill pipe. For the directional wells provided by HWDP
Drilling pressure and additional stiffness to prevent buckling.
Specification. Heavy-duty drill pipe
