RDS Engineering manufactures a full line of double tube core barrels in accordance with ISO Standards and DCDMA. Use: Double tube core barrels are used for a variety of purposes, including diamond core drilling, tunnel drilling, geotechnical analysis, soil testing, drainage, and grouting holes. Method: The inner tube is connected to the core barrel head by bearings in double tube core barrels, which allows the inner tube to rotate independently of the core barrel. The outer tube and inner tube of the double tube core barrel are filled with water. The inner tube bottom end has perforations that allow water to pass through. The only part of the core that is prone to corrosion is up to the diamond core bit. In relation to the overall length of the two tube core barrel, this distance is quite short. It is conceivable to accept a core made of softer and fractured materials once the erosion issue has been resolved. It delivers an improved rate of core recovery and little core erosion. Specification and standard size: AX double tube core barrel core diameter of 30.1 mm and a Drilling hole diameter of 48 mm. BX double tube core barrel core diameter of 42 mm and a Drilling hole diameter of 60 mm. NX double tube core barrel core diameter of 54 mm and a Drilling hole diameter of 76 mm. HX double tube core barrel core diameter of 76 mm and a Drilling hole diameter of 100 mm.
