4" 102mm Reverse Circulation Drill Rods RC Drill Pipe For RC Drilling
Product specifications:
RC Hammers
Dual-Wall Drill Rods (RC Drill Pipes)
RC Drill Bits
RC drill rod (also as dual-wall drill pipes) comprises an outer and
inner pipe
with a sealing system (usually O Rings) to keep the drill string
pressurized.
Air is blown between the walls of the inner and outer pipes down to
the hammer
while the air forces the cuttings back up through the centre of the
inner pipe.
As RC drill rods are subjected to high wear in the drilling process
we
use only the high quality hardened alloy steel for the both rods
and tool
joints.
