We offers a full range of surface application core barrels. Available in standard double tube core barrels for easy conversion to triple tube configuration in broken ground.
The core barrel assembly is composed of the inner-tube group and outer-tube group.The inner-tube group is composed of:
Head Assembly
Inner Tube
Core Lifter Case
Core Lifter
Stop Ring
The inner-tube group collects the core sample during the drilling process and is independent of the outer-tube group. The outer-tube group is composed of the remainder of the core barrel components:
Locking Coupling
Adapter Coupling
Outer Tube
The outer-tube group always remains at the bottom of the hole and houses the inner-tube group during the drilling process.
