[Company Introduction]

Our company is the only manufacturer of drilling equipment in Korea who is specialized in producing equipment and materials that are needed in the boring works of exploration and civil engineering construction in domestic and overseas markets.
 Currently, we are supplying our products to customers at reasonable prices through the localization of the market that has been occupied by the imported products based on our know-how accumulated for a long time and endless research and development.
 We are also a small but strong company that is spurring to develop overseas markets equipped with international competitiveness.
 At present, we are positioned as the best company not only in the domestic market but also in whole Asian regions among the self-manufacturing companies, and all the staff are trying their best together to become a major player in the global market.
 Taesung Co. will keep the immovable top position in the boring works of construction and civil engineering in the domestic market.
 It is said that the winner will be determined by the knowledge and resources in the future.
 In parallel with this global trend, Taesung Co. will make endless efforts as a professional manufacturer of the exploring equipment of natural resources.
 Thank you.

USAGE

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 the 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 on ground/soil that is easily collapsed or eroded by the circulation water.   2. Double Tube Core Barrels : AX, BX, NX, NXD3, T76, T56 These are made of double 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 in increasing the core collection rate.   3. Triple Tube Core Barrels : NS3, HS3, PS3 Triple tube core barrels have an almost identical structure with Double tube core barrels, but a tube for the core case is built 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 ground 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 This equipment is 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 greater the depth of the hoisting works, the greater the number of rods becomes and the weight of the rods as well as the cost, time, and labor of works. In order to solve these 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

Features

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