Drill pipe DTH

In Down-the-hole (DTH) Drilling the percussion mechanism – commonly called the hammer – is located directly above the drill bit. The drill pipes transmit the necessary feed force and rotation to the hammer and the bit. Rotary Drilling does not require a hammer. Instead, rotary drilling creates a very large compressive force along the drill string to the drill bit, in combination with rotational movement. We offer: Drill pipes from 35 to 300 mm OD – up to 219 mm OD in friction welded version Available for rigs from EPIROC, Sandvik, CAT, Bucyrus, Cubex, Driltech, Hausherr, Ingersoll Rand, Nordmeyer, Prakla, Soilmec/Drillmec and many other Standard thread types like API Regular, API NC, API FH, API IF, BECO, Cubex, Z-threads, RD (round threads) and many more Casings Drilling Tools: drill bits, drill collar, Stabilizer, subs, check valves, hoisting equipment, fishing equipment etc. Optional hard facing for wear protection in abrasive ground conditions
