Di-Corp has a solution for extending your standard Core Barrel. Whether you’re coupling two standard Core Barrels together or simply extending an Inner Tube Assembly to match a stabilized Reaming Shell, Di-Corp has what you require to get the job done.

In consolidated ground conditions, a core barrel assembly can be extended in order to double or even triple a core run - from 1.5 m (5 ft) to 4.5 m (15 ft), or 3 m (10 ft) to 6 m (20 ft) lengths. This can increase your productivity significantly. 

Example: 

To assemble a 6 m (20 ft) core barrel, use a 3 m (10 ft) core barrel assembly plus 1 outer tube 3 m (10 ft), 1 inner tube 3 m (10 ft), 1 inner tube stabilizer and 1 inner tube coupling.

Note: It is recommended to use a stabilized reaming shell if extending the core barrel.
