ROSCHEN Drill Pipe and Heavy Weight Drill Pipe
Drill pipe is one of the necessary components to any drilling rig designed to extract oil or other liquid materials from the ground. The drill pipe 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.
How to Work with Drilling Pipe
The drilling tool is connected drill rod for transferring power. The drill string is usually part are: drill, drill collars, drilling 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.
ROSCHEN Heavy weight drill pipe Advantages
a. Heavy weight drill pipe could replace part of drill collar can reduce torque, improve load, and increase drilling capacity during deep well drilling.
b. To pick-up sub and safety clamp that not used during drilling operation, which is easy to operate and can save tripping time.
c. Drilling in high speed under low torque in directional wells and reduces the abrasion and fracture of string without differential pressure and sticking because of the lower steel grade than drill collar, small touching area with the well wall.
