T2 Series Double Tube/Triple Tube Core Barrels
The T2 Series are thin wall double tube core barrel, used for
surface exploration, especially mining applications. Due to their
thin kerf, these core barrels provide rapid penetration. Available
in diameters 46, 56, 66, 76, 86, 101mm.
T6 Series Double Tube/Triple Tube Core Barrels
These are a continuation of the T2 series, but of a sturdier design
and available in larger diameters, 76, 86, 101, 116. 131 and 146mm.
They are applied in surface mining and geotechnical drilling.
Coreliners are rigid, transparent PVC tubes with a wall thickness
of approximately 1 mm, that fit snugly inside the core barrel inner
tube.
Coreliners can be supplied to fit most types and sizes of core
barrel - metric, DCDMA and wireline. It is normally supplied in
standard 5-10ft lengths, with or without plastic end caps.
To use the coreliner system a modified Core Bit and Core lifter is
required with reduced internal diamete. This is to ensure that
there is adequate clearance for the core to fit into the plastic
coreliner tube. Such "coreliner set" bits and core lifters are
available on request.
