Our company is specialising in drilling rigs and drilling parts for decades. We have exported to more than 30 countries all over the world. We have kinds of drilling rigs, such as DTH (Down The Hole) drilling rig, Water well drilling rig, Oil well drilling rig, Piling drilling rig with different types of Truck Mounted, Trailer Mounted and Crawler Type. For drilling parts, we have the follwings: DTH hammers/bits, Tricone bits, PDC Bits, Button Bits, Chisel Bits, Drill Pipe, Pick Cutters etc.
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, from 1000mm to 6000mm length of pipe are available.
