Product Description
Down th hole drill pipes 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. Sollroc DTH drill pipes are made of
superior alloy and the both thread ends are friction welded to the
seamless steel pipe.The high pressure air is delivered to DTH
hammer by DTH drill pipe, simultaneously it transfers the rotation
and press force to the DTH hammer.
DTH drilling tool is a kind of drilling system which uses
compressed air as motivation, makes drilling impact motivation
parts down the hole, to control the piston reciprocating motion by
the distribution device in the hammer, and then impacts the DTH bit
in the front of the hammer to transit the impacting power to the
bit. The DTH bit in the front of the hammer breaks the rock to
drill hole.
