Complete Single Tube Core Barrels
Specifications
The LTK series core barrels system is a thinner wall core barrel than T2 series. They offer a cost effective, high productioncore Double
Double Tube Core Barrels
TT Series Core Barrel
thin walled double tube core barrels, available diameters 46 and 56 mm.
Very thin cutting face allows very rapid rate of penetration through hard formations.
They are suitable for underground mining applications
T2 Series Double 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 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
LTK 48 & LTK 60 Double Tube Core Barrels The LTK series core barrels system is a thinner wall core barrel than T2 series. They offer a cost effective
high production, which is designed for optimum production and core recovery in medium to extra hard rock formations.
Available sizes 48 and 60mm
WF Series Double Tube Core Barrels They are geotechnical core barrels primarily designed for coring relatively soft formations in using face-discharge bits. Simple construction and more resilient to damage than thin-wall barrels,but with slower enetration rate.
WG Series Double Tube Core Barrels There are Double tube core barrels for WG series. Available in DCDMA sizes E, A, B, N, and H.
BW and TNW Core Barrels
These are thin-walled double tube core barrels, as T2 series but with DCDMA hole sizes B and N. Used for surface exploration, specially mining applications.
The thin kerf area allows rapid penetration.
Wireline Double Tube Core Barrels Wireline double core barrels are primarily used in deep coring. With an overshot device,
they eliminate the need to couple and uncouple the rod string each time the core is retrieved.
Available in DCDMA sizes A, B, N, H ,and P.
Chinese Standard Double Tube Core Barrels
Chinese Standard Wireline Double Tube Core Barrels
Jet-type Reverse Circulation Double Tube Core Barrels
Triple Tube Core Barrels
MLC (Triefus) Series Core Barrels
These triple tube core barrels are generally used for geotechnical purpose, designed to maximize core recovery in soft formations.
Available diameter sizes from 35-146mm.
Wireline Triple Tube Core Barrels
Wireline triple tube core barrels are generally required in broken, fractured formations.
They incorporate a third, split inner tube on base of wireline double tube core barrel.
core barrel complete include 1head assembly 2 inner tube and outer tube 3 locking coupling & adapt coupling4 core lifter & core lifter case
1head assembly

2 inner tube and outer tube
