 1.5m and 3m Core barrel demension:



Q Series 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 sizes in AQ, BQ, RQ, NQ, HQ, and PQ.


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.


TT Series Core Barrels:

Very thin cutting face allows very rapid rate of penetration through hard formations. They are suitable for underground mining applications.


LTK48 & LTK60 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 size 48 and 60mm.


WF Series Double Tube Core Barrels:

They are geotechnical core barrels primarily designed for coring relative soft formation 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 Core Barrels:

There are double tube core barrels for WG series. Available in DCDMA size E, A, B, N and H.


MLC Series Triple Tube Core Barrels:

These triple tube core barrels are generally used for geotechnical purpose, designed to maximize core recovery in soft formations. Available diameter size 35-146mm.


Wireline Triple Tube Core Brrels:

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.
