Specification of Drill Pipe 

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.

 Product Advantages of Drill Pipe 

1. To reduce tripping time. By using wireline replacement than traditional drill with drill rod from about 5-10 times faster;
2. Save the drill pipe and drill collars related procurement, transportation, inspection, maintenance and replacement costs;
3. Because there is always the wellbore casing, no longer have the time to drill down from the pumping action within the wellbore, the well control situation has improved;
4. Due to the elimination of the drill pipe from the pumping action and bring pressure pulsation;
5. Maintained when the wire rope from under the continuous circulation drill mud, cuttings prevents aggregation also reduces the occurrence of a kick;
6. To improve the return on annular velocity and cleaning the wellbore conditions. When the sleeve is pumped into the mud because of an inner diameter larger than the drill pipe, reducing the          hydraulic losses, which can reduce the drilling rig mud pump with power. Mud returns from the annular space between the casing and the borehole wall, since the annulus area is reduced, 

    improving the return on the speed and improve the drill cuttings taken out of the situation;

7. The size can be reduced rig, the rig structure to simplify and reduce the cost of drilling rig;
8. Rig more lightweight, easy to move and operate. Manual labor and costs are reduced.
