Double Tube Core Barrels
 

 

 

 

--- TT Series Core Barrel
Ultra-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 forunderground 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 single tube core barrels for WG series. Available in DCDMA sizes E, A, B, N, and H.
---TBW 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 eliminatethe 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. This can be pumped out of the inner tube after retrieval, allowing the core to be examined in its in-situ state.



Single Tube Core Barrels

--- B Series Single Tube Core Barrels
B series are single tube core barrels, often used in situations where core preservation is not essential and for concrete coring. Available diameters 46-146mm.
--- WG Series Single Tube Core Barrels
There are double tube core barrels for WG series. Available in DCDMA sizes E, A, B, N, and H.
--- Chinese Standard Single Tube Core Barrels
