Core barrel is the complete drilling tool assembly, it’s the part of machinery used for drilling extremely hard formations like mineral site or water well with rock bottom. Three types of core barrels we offered: single tube core barrels, double tube core barrels, triple tube core barrels. And length is available in 1.5 meters and 3.0 meters. The whole complete core barrel is made up of many spare parts, they are head assembly, pump-out adaptor, piston plug, O ring, core ejection piston, split tube, inner tube, extension tube, stop ring, core lifter, core lifter case, locking coupling, adaptor coupling, landing ring, outer tube, inner tube stabilizer, thread protector. core bit and reaming shell are not supplied in the core barrel and need to be ordered separately. Many geological survey and companies involved in mining exploration works use this type of equipment. |

core barrels use inner as well as outer core for taking samples of the minerals and rocks even while drilling process is in progress. In case the material of the rocks is too hard penetrate by the standard rotating barrel, diamond core bits are used to increase its potential. Now it is ready to cut away the sample by inserting the diamond core bit into the well in existence and rotating the outer barrel around the inner barrel. This technique can also be used to prevent the entry of external water into the core sample when extraction process is progressing. |
core barrel is a sophisticated tool for drilling. Technically, it is an assembly for drilling tool, which is a section of the machinery used for drilling the surfaces that are extra hard, like in mineral sites. The company offers three types, including the triple tube core barrels, double tube and singe tube core barrels. They will measure between 1.5 to 3 meters and they are made of different parts altogether. They will be used to take the mineral and rock samples when drilling is taking place. |

| 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 |
WG series available in DCDMA sizes E,A,B,N and H. |
| Chinese Standard Single Tube Core Barrels |
|
|
| |
| 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 |
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 |

| |
| 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. |
