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.

The ability to complete all phases of manufacturing under one roof is significant as it allots DPI 100 percent control of the tooling`s quality and, ultimately, this translates to a highly reliable product, with unparalleled product performance in the field.

We rely on our expert machinists, who are experienced professionals, and utilize the latest CNC Machining Center Technology - Employ Advanced Inertia Welding Technology - Insist on use of Premium Alloy Steel from US Steel Mills - Apply leading edge Heat Treatment science, and technology - and meticulously apply our strict process step Quality Control System.

We participate in the following industries and gain synergy from providing real solutions to a diverse array of challenges:

Water Well
Geothermal
Civil Construction
Mining
Geotechnical Environmental
Horizontal Directional Drilling

The focus on product quality and performance is our mantra and is an ongoing effort, which we pursue like no other organization.

DPI is a medium-sized business, and this enables us to be very sensitive to our customer`s needs, and offer flexibility others cannot. We plan our business to reduce manufacturing time.

Looking for one piece of drill rod or several hundred, you can count on DPI for both our product quality, and our short lead times.

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.

At DPI, we use the highest-quality Material, Cutting-Edge Heat Treatment Technology, Multiple Welding Processes, CNC Machine Centers, Thread Gauges, and Computer-Assisted Design Tools. Our Goal is to satisfy the toughest critics in the industry, and provide exceptional value to our customers. Each step of our manufacturing process is closely monitored by our Quality Control Personnel, who have a distinctive role in our business. A history of success proves it.

Our Down Hole Tooling provides performance our customers rely on. We offer the most durable products on the market. Drill with Confidence; Drill with DPI Products.

We manufacture Down Hole Drill Tools to OEM specifications and to custom requirements. Our people, planning, and facilities are all geared to allow for a combination of longer production runs, yet flexible enough to accommodate time-sensitive customer needs.

We invite you to experience the DPI difference.
