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.

Features:

1. Made of 4145H alloy structural steel. 
2. Production complies with the provisions under the Standard SY/T 5146-1997. Connector screws comply with the provisions of the Standard API SPEC 7-1.
3. The tube section has a larger diameter at mid length to protect the heavy weight drill pipe from wear.
4. Hardbanding and Internal Coating can be provided on customer's request.
