Product Description:

WG and WF series double tube core barrels are sturdily designed for coring soft to medium 聽rocks using water, polymer or mud flush. The WF series utilize core bits with face discharge flushing ports to prevent core erosion in soft soils and soft rocks. The WG series utilize core bits with internal discharge flushing and are designed for slightly harder formations.

These core barrels are intended for use in conjunction with DCDMA drill rods and casing.

Mark & model: The available DCDMA models: EWG, AWG, BWG, NWG, HWG.

—WM Series Double Tube Core Barrel
WM 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.

These聽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聽Core聽Barrels
Wireline triple tube core barrels are generally required in broken, fractured聽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聽Core聽Barrels
B聽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.
