Reverse Circulation Drill Pipe 4 1/2'' Remet Thread For RC Hammer
Bit
Selecting the right drill pipe
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 .
