Profile: E&M Specialty Company is a provider of used drill pipe, used & remanufactured drill collars, heavy-weight drill pipe, and other related drill string components. We also carry a complete line of new drill pipe, drill collars, heavy-weight drill pipe, and kellies. We serve the oil & gas drilling, horizontal directional drilling, and the water well drilling industry. We sell new drill pipe that is manufactured only by A.P.I. certified drill pipe manufacturers. Drill pipe is an industrial tubular used to drill into the ground. The most common application of drill pipe is in the oil and gas industry. Drill pipes are normally made in 31 ft lengths. These lengths are screwed together one by one and collectively are known as the drill string. Also parts of the drill string are drill collars and heavy-weight drill pipe. At the bottom of the drill string is the drill bit, which does the actual boring into the earth. Initially, all oilfield drill pipes are drilled into the ground vertically by the drilling rig. We sell new, used, and remanufactured stock drill collars. Our new drill collars are made to outperform all industry requirements. In their initial phase of manufacturing, the drill collars are solid round bars of 4145 carbon steel. We also sell stock drill collars. The stock collars are drill collars that have undergone so much usage that the overall diameter and weight of the drill collar is reduced. Once this has occurred, certain size drill collars can be cut up & used as stock material to build subs, stabilizers, and various other specialty drilling tools. Drill collars are extremely heavy duty industrial tubulars used to drill into the ground, and are usually used in conjunction with drill pipe.
