Aq Bq Nq Hq Pq Wireline Drilling Double Tube Core Barrels

Product DescriptionCore 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.  Size Q Series Wireline Double Tube Core BarrelsSizeHole(mm)Core(mm)Head ThreadBQ59.336.2BQ rod boxNQ75.247.6NQ rod boxHQ95.663.5HQ rod boxPQ12285PQ rod boxQ Series Wireline Triple Tube Core BarrelsSizeHole(mm)Core(mm)Head ThreadNQ375.245NQ rod boxHQ395.661HQ rod boxPQ312283PQ rod boxWireline series: AQ, BQ, NQ, HQ, PQ, PQ3, HQ3, NQ3, BQ3, NQ2, BTW, NTW, HTW, SK6L 146, Geobor S146T2 series: T2 46, T2 56, T2 66, T2 76, T2 86, T2 101TT series: TT 46, TT 56T6 series: T6 76, T6 86, T6 101, T6 116, T6 131, T6 146T6S series: T6S 76, T6S 86, T6S 116, T6S 131, T6S 146B series: B46, B56, B66, B76, B86, B101, B116, B131, B146C series: BMLC , NMLC, HMLC, 3C, 4C, 6CLTK series: LTK48, LTK60WF series: HWF, PWF, SWF, UWF, ZWFWT series: RWT, EWT, AWT, BWT, NWT, HWT(Single Tube, Double Tube)WG series: EWG, AWG, BWG, NWG, HWG(Single Tube, Double Tube)WM series: EWM, AWM, BWM, NWM, HWMOther sizes: AX, BX, NX, HX, TBW, NQTT, HQTT, TNW, 412F, BTW, TBW, Denison, MazierChinese standard: 56mm, 59mm, 75mm, 91mm, 110mm, 131mm, 150mm, 170mm, 219mm, 275mm  Related Photos   Packaging & Shipping   Product Features ---Wireline Double Tube Core Barrels Wireline double tube core barrels are primarily used in deep coring. With an overshot device, they eliminate the need tocouple 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 totheir 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 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  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 BarrelWM 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 BarrelsThese are thin-walled double tube core barrels, as T2 series but with DCDMA hole sizes B and N. Used for surfaceexploration,  specially mining applications. The thin kerf area allows rapid penetration.---MLC Triple Core BarrelsThese 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 BarrelsWireline 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 BarrelsB 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.---Chin
