Product Description

                     Wire Line  NQ Core Barrel 1.5M and 3.0M 

Product Description

 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 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.

---Double Tube Core Barrels Wireline Double Tube Core Barrels
In sampling by wireline core drilling, a double-tube or triple-tube core barrel with a bit fitted to the lower end is rotated and fed into the rock type to be drilled by the drill rig via the wireline drill rods. This action produces a core sample within the inner tube of the core barrel. When the coring run is completed, the inner tube containing the core sample is withdrawn through the drill rods by means of a wireline cable and winch. The bit, outer tube and drill rods remain in the borehole during this process. 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 A, B, N, H, P, S and Chinese Standard core barrels.                                                                                                                                                                                                                                      

---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 There are Double tube core barrels for 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 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.

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.

Quality Guarantee

Our Company pas atention to produce quality and abides to credit, and also does the best to provide the quality produdcts and excellent service to customer. To build good after-sale service system, we draw up the Quality Guarantee according to the industrial standards combining field experience. 

Diamond Drill Bits	1. Size, and / or technical parameters(matrix etc.) are different from the requirements of clients' purchase order.	Replace
	2. Thread can not fit clients' barrel.	Repair    or replace
	3. Break down a piece from matrix, and the volume of the piece exceed 2mm*2mm*2mm, and such break is not caused by drilling.	Replace
	4. Matrix falling not caused by drilling.	Replace or return
	5. Groove on matrix caused by manufacturer.	Replace or return
	6. Drilling speed is obvious slower than congener products caused by manufacturer.	Raplace,and each item quantity does not exceed 3pieces.
	7. Bit life is obvious short caused by manufacturer.
	8. Breaking down of matrix, falling matrix, groove and short bit life caused by operating reasons-drill rod sticking, premature failure of the bit crown and hole-bottom not to be cleaned.	Be excluded from Qulity Guarantee
	9. Short bit life or no penetration caused by drilling machine, drilling techniques or parameters.
	10. Properly worn and the matrix is finished.
