DTH drill tubes are used for connecting DTH hammer and DTH button
bits; they are made from seamless tubes. Tubes play a significant
role in all DTH drilling, regardless of application, rock type,
hole depth or drill rig. The key features of a high quality DTH
tube are durability, accuracy and manageability. 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,
102mm etc. ALL DTH drill tubes are friction welded, and 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 tubes are available.
