WG and WF Series Double Tube Core Barrels
WG and WF Series Double Tube Core Barrels
WG and WF series double tube core barrels are sturdily designed for coring soft to medium rocks using water, polymer or mud flush. The WF series utilize core bits with face discharge flushing ports to prevent core erosion in soft soils and soft rocks. The WG series utilize core bits with internal discharge flushing and are designed for slightly harder formations.
These core barrels are intended for use in conjunction with DCDMA drill rods and casing.
Advantages:
1. Simple sturdy design
2. Can be used when DCDMA hole sizes N, H, P and S are required.
