T2 series are thin wall double tube core barrels, used for surface exploration, especially mining applications. Due to their thin kerf, these core barrels provide rapid penetration.

The T2 series core barrels are suitable for coring in all formation types. The barrel is designed to be used with core bits with a relatively thin kerf to maximize the rate of penetration. These barrels should be used with water or mud as the flushing medium. The T2 series are also available in DCDMA hole sizes B and N: these barrels are denoted TBW and TNW, respectively.The corelifter case is a push fit directly onto the extension tube and it slides down to rest on the bit when the core is broken. Thus the entire load of the core is transferred to the outer tube. This design is especially advantageous when working with large or heavy cores to prevent overloading the bearings and therefore prolonging the life of the barrel.The inner and outer tubes are manufactured to our own specification from cold drawn tube of a very high tensile strength and straightness. The head is manufactured from heat treated alloy steel to ensure a long life.T2 barrels can also be used with plastic 鈥淐oreliner鈥 tubes with an undersize bit and corelifter, to obtain an instantly 鈥減ackaged鈥 core.

Size: T2-36, T2-46, T2-56, T2-66, T2-76, T2-86, T2-101.

—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.

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.
