Drill Pipe

Drill pipes are long tubular sections of pipe that make up the majority of the drill string. They are manufactured according to the requirement of API 5DP.

Drill pipe is hollow, thick-walled piping that transmits drilling fluid and torque through the wellbore to the drill bit on a drilling rig. It is manufactured to withstand severe internal and external pressure, distortion, bending, and vibration as it both rotates and lifts the bottom hole assembly. Drill pipe is threaded on each end in a section of pipe referred to as the tool joint.
