Since the early 1960s, Drill Pipe Inc. personnel have innovated and progressed both the design and process quality to manufacture quality Down Hole Tools. Our history started in Wire Line Drill Rod Design in the 1960s, and progressed with the development of the first Inertia Welded Drill Pipe in the 1970s.
In the 1980s, we designed the "Inertia Welded Sucker Rod for the Oil and Gas Industry". In the 1990s, we innovated many of the HDD Drill Pipe Designs that are still used today.
Early in the year 2000, we began the design and patenting process of the Strongest Pound-for-Pound Helical Pier in the world. In 2010, we engineered, developed, and manufactured the Drill String that was used in the Chilean Mine Rescue.
