Drill Pipe: Drill pipe includes pipe body and tool joints(box and pin) welded together, used to connect drilling rig surface equipment and bottom equipment or bottom hole equipment. Drill pipe can bear heavy internal and external pressure, and twist, bend and vibration which can be used more than one time during oil or gas production.

Drill pipes are steel tubulars fitted with threaded ends called tool joints, which are commonly used in tension in the top part of the drill string to pump fluid and transmit torque to the bit.
