66mm 76mm 86mm 101mm 116mm 131mm 146mm Metric Casing Tubes
- Description
- Inquiry
Standard lengths are 3.0m, 1.5m, 1m, and 0.5m. Other lengths are available on request.
The casing tubes are designed to be used in conjunction with TT, T2 and T6 series metric core barrels. For example, a T2-86 core barrel will fit inside 101 metric casing, and a T6-101 core barrel will fit inside 116 metric casing, etc.
The clearance between the core barrel and the inside of the casing tube is quite small, reducing the volume of water that is required for flushing, and creating a high up-hole fluid velocity which facilitates efficient removal of rock cuttings from the borehole.
