Product Details

Downhole Integral Heavy Weight Drill Pipe, API Drill Rod, HWDP in Oil and Gas

Product Description

We supply integral heavy weight drill pipe from 3-1/2” to 6-5/8”. Also can supply friction welded HWDP, which is assembled with AISI 1340 steel pipe and AISI 4145H or 4137H tool joints. The HWDP is intended primarily for directional drilling. As it bends easily, it simplifies directional control and minimizes connection fatigue problems common to high-angle or horizontal drilling.

* HWDP include:

Integral HWDP (3 1/2” – 6 5/8”),

Integral Spiral HWDP (3 1/2” - 5”)

Friction Welding HWDP (3 1/2” to 6 5/8”).
