Drill pipe is a heavy, seamless tube can rotate the drill bit and circulates drilling fluid. It allows the drilling fluid to be pumped through the bit and back up the annulus. The pipe is subject to axial tension, extremely high torque and high internal pressure.
Drill Pipe is durable steel pipe used in drilling activities, standards in API 5DP and API SPEC 7-1.
Drill pipe is an important components for drilling rig to extract oil or other liquids from down ground. It is not used for extraction, instead, the hollow tubes pump drilling fluids downward to the bit and back out again as needed to reduce friction and heat buildup. Drill pipe transferred drilling torque to drill bit for drilling under the oil well. It bears complicated strength subject to pulling, loading, pressing, torsion and bending.

The drilling tool is connected drill rod for transferring power. The drill string is usually part are: drill, drill collars, drill pipe, stabilizers, special connectors and Kelly. The basic role of the drill string are: (1)control the drill bit; (2) imposed WOB; (3) transmission of power; (4) transporting drilling fluid; (5) special operations: extrusion of cement, handling underground accidents.
API 5DP drill pipe is trailing with screw thread for connecting the drilling rig located at the bottom of surface drilling equipment and mill equipment or bottom outlet device. The purpose is to drill the drilling mud delivered to the drill bit, and drill with the increase, decrease or rotating bottom outlet means. Drill pipe must be able to withstand great external pressure, twisting, bending and vibration. In the mining and oil and gas refining process, the drill pipe can be used multiple times.
