Wired Drill Pipe Description:


Drill pipes that are used in applications such as DTH/ DTHR/ DR basically comprise of a steel pipe with a pin at one end and a box on the other. The job of the drill pipe is to transmit rotational torque and thrust from the drill rig rotary head to down hole drilling tools.

According to different application, different diameters of drill tubes are needed, basically, smaller DTH hammers need smaller DTH drill tubes, vice versa. Usually we are offering 50mm, 60mm, 76mm, 89mm, 95mm, 102mm, 114mm 127mm, 140mm, 159mm etc.

Usually the threads are standard API connections, like 2 3/8" API REG thread, 3 1/2" API REG thread or API IF thread, etc.
According to customers request, from1000mmto6000mmlength of pipe are available.

Wired Drill Pipe Features:


1. Thread oil should be used when screwing the drill rod and hammer knocking should be prohibited.
2. The drill rod stand should have buffer materials, like wood, rubber, and more. The contact between the threaded ends and iron tools should be forbidden.
3. During the relocation of drill rod, the thread protector should be screwed on the threaded parts so as to protect it from damages.
