Early in the 1990s, DPI engineers began designing and manufacturing some of the first HDD drill pipe.
We innovated, and manufactured the first Dual Tube Outer Casing. Many of the drill pipe configurations that we developed work as mainstays in the industry today.
DPI utilizes a combination of upsetting, Inertia welding, Heat Treatment, Careful Selection of High Performance Alloy Steel, along with our knowledge, and expertise, to manufacture the finest HDD rod in the industry. The Mantra of DPI is quality and performance - and everything we do is aimed at maximizing these values for our customers.
