Massive Selection for Mining Drill Pipe - Rock Drill Pipe – TDS Detail:

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.

According to customers request, from 1000mm to 6000mm length of pipe are available.
