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 for underground mining applications. |
---T2 Series Double Tube Core BarrelsThe 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 BarrelsThese 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 BarrelsThe 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 BarrelsThey 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 BarrelsThere are Double tube core barrels for WG series. Available in DCDMA sizes E, A, B, N, and H. |
---TBW and TNW Core Barrels The thin kerf area allows rapid penetration. |
| ---Wireline Double Tube Core BarrelsWireline 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. |
