Our Heavy Weight Drill Pipe (HWDP) offers a gradual transition from heavy, rigid drill collars to the more flexible drill pipe which helps to reduce
We offer heavy weight in 3.1/2″, 4", 5″ and 5.1/2″ consisting of hard banded tool joints and raised wear pads on central upsets to optimize wear
We offer two types of HWDP configurations; Standard HWDP and Spiral HWDP.
Prevents stress concentration and allows directional drilling with controlled torque and reduces differential pressure sticking.
Shares many of the same features from the Standard HWDP.
Better reduction in differential sticking
Increased weight and stiffness
Improves cutting circulation for better hole cleaning
Our preferred applications of hard banding for drill pipe tool joints and BHA components (HWDP, Drill Collars) are ARNCO 350XT or Duraband NC, both NS-1 certified; which are not only designed to protect the drill pipe from wearing but also to protect the casing. We use a robotic welding system for
