Choosing the Right Casing for Core Drilling Success

Selecting appropriate casing for exploration coring drill rigs or portable full-hydraulic core drilling rigs can significantly impact the efficiency and safety of drilling operations.

1. Material Selection: Steel vs. PVC
Steel casing is ideal for multi-functional crawler drills working in tough geological conditions, as it offers superior strength and durability. However, PVC casing may suffice for shallower boreholes or when cost constraints exist.

2. Diameter and Thickness
The diameter of the casing should match the size of the drill bit and core barrel to ensure a snug fit. For deep drilling using a rock exploration drilling system, thicker casing walls are necessary to withstand high pressure.

3. Connection Types: Threaded vs. Welded
Threaded casing offers ease of assembly and disassembly, making it suitable for portable rigs. Welded casing is more robust and better suited for permanent installations or demanding conditions.

4. Cost vs. Longevity
Investing in high-quality casing materials can reduce long-term costs by minimizing downtime and equipment damage. Professionals using advanced rigs like the portable full-hydraulic core drilling rig often prioritize quality over initial expense.
