We offer a complete line of single & double and triple tube core
barrels, which will provide superior performance and obtain the
full recovery of the sample in any application of diamond core
drilling.
Using a wireline system , core is recovered quickly by retrieving
the inner tube directly through the drill string. The rods remain
in the hole until the bit needs to be replaced. this has big cost
advantages when drilling deep holes for mineral exploration.
The core barrel assembly is composed of the inner-tube group and
outer-tube group.
The inner-tube group collects the core samples during the drilling
process and is independent of the outer-tube gourp.
The outer-tube gourp always remains at the buttom of the hole and
houses the inner-tube group during the drilling process.
The standard wireline Double tube inner-tube gourp is composed of
Head Assembly, Inner tube, Core lifter case , Core lifter, Stop
ring.
The outer-tube group is composed of the remain of the core barrel
components: Locking coupling, Adapter coupling, Outer-tube, Landing
ring, Inner tube stabilizer.
Standard Wireline Double tube Core Barrels are ideal for use in
most of the drilling conditions and are available for application
in standard hole sizes( B,N,H,P).
