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.
