Drill pipe is an industrial tubular used to drill into the ground. There are three major industries that use drill pipe. The most common application of drill pipe is in the oil and gas industry. Another industry that uses drill pipe is the underground construction industry, or more specifically, the Horizontal Directional Drilling (HDD) industry. And finally, the water well drilling industry also uses drill pipe.
