Product Description

Core Barrels include single tube type, double tube type and triple tube type.

Wireline core barrels eliminate the major time consuming operation of using standard double tube core barrels - pulling, stacking and lowering drill rods each time the core barrel is full.
 
Using a wireline system, core is recovered quickly by retrieving the core-laden inner tube directly through the drill string. The rods remain in the hole until the bit needs to be replaced. This has major cost advantages when drilling deep holes for mineral exploration.
 
These core barrels are available in industry standard hole sizes A, B, N, H and P. All parts are fully interchangeable with most other manufacturers' wireline core barrels. Special requirements can also be met on request.

---Wireline Double Tube Core Barrels 
Wireline double tube 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.

---TT Series Double Tube Core Barrels  
Ultra-thin wall double tube core barrels, available diameters 46 and 56 mm. Very thin cutting face allows very rapid penetration rate 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  penetration rate.

---WG Series Double Tube and Single Core Barrels 
There are single and double tube core barrels for WG series. Available in DCDMA sizes E, A, B, N,  and H.

---WM Series Double Tube Core Barrel
WM series double tube core barrels was developed as a solution to the ever present problem of recovering a high percentage of core when drilling badly fractured or broken strata or soft and friable material that is easily eroded by the circulating fluid. Mud or water can be used with this core barrel while drilling. It has more sturdy design compared to the metric series core barrels.

---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.

---MLC Triple 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.

---B Series Single Core Barrels
B Series are single tube core barrels, often used in situations when the core preservation is not essential and for concrete coring. Available diameters 36-146mm.
