It is a device to take the cores drilled by the core bit, and made of pipe.
Core barrels are mostly used to take the core, but sometimes they are used to increase the drilling efficiency even in case core is not needed. There are several kinds of Core Barrels in accordance with the usage;

  1. Single Tube Core Barrels : AX, BX, NX
    - These are generally used to increase the collection rate of cores at an even ground. They cannot be used at the ground that can be easily collapsed or eroded by the circulation water.
  2. Double Tube Core Barrels : AX, BX, NX, NXD3, T76, T56
    - These are made of duble tubes (Outer Tube, Inner Tube), and circulation water passes through the gap between the tubes and is not touched by the collected cores. They are not suitable to be used for the geological strata where core collection is difficult due to uneven strata with many cracks, coal beds, and soft layers. Also, they play a role to increase the core collection rate.
  3. Triple Tube Core Barrels : NS3, HS3, PS3
    - Triple tube core barrels have almost same structure with Double tube core barrels, but a tube for the core case are built at inside the Inner tube. The Inner tube can be easily removed from a Core case tube along with the cores taken into the Inner tube. It is a product that is made to collect the fresh cores without disruptions from the weak grounds or broken layers where core collection is difficult with normal Double core barrels.
  4. Wire Line Core Barrels : BS, NS, HS, PS Wire line Core Barrels
    - These equipment are used to hoist the rods during the drilling and core collection works by the bits of Core barrels or at time of bit changing. The bigger is the depth of the hoisting works, the more becomes the number of the rods and the weight of the rods as well as the cost, time, and labor of works. In order to solve the problems, Wire line core barrels have the Inner tube that is built in the Outer tube, and hoist the Inner tube onto the ground within the hole by use of wire rope. If you use this Core barrel, the number of hoisting of the Rods is reduced, and this is the most reasonable Core barrel especially for the drilling of the cores from the deep layers.
  • You may not hoist the drilling equipment except when you replace the Bits, and the drilling time is increased as the hoisting time and labor of the drilling equipment are saved.
  • The generations of irregular vibration of rods are less, and the fear of collapsing of the hole as well as the accident of detained rods is also less.
  • Structure : Outer Tube, Inner Tube, Over Shot, Wire Line Drill Rods, Hoisting Plugs


Taesung's Core Barrels are made of raw materials of best quality appropriate for the drilling, so they are excellent in life span and quality and currently being exported to various countries such as Kazakhstan, Mongolia, Uzbekistan etc.
