FAQ:
1. What is casing drilling?
Casing is a large diameter pipe that is assembled and inserted into a recently drilled section of a borehole. Similar to the bones of a spine protecting the spinal cord, casing is set inside the drilled borehole to protect and support the wellstream.
2. Why is percussion drilling used?
Cable percussion drilling is a tried and tested method of site investigation. The drilling technique allows the installation of casing inside the borehole to prevent loose soils collapsing into the hole, allowing the borehole to be advanced to considerable depths while maintaining good progress.
3. How much PSI do I need for air tools?
Between 70 and 90 PSI
Most air tools require between 70 and 90 PSI. Any light-to-medium-duty air compressor can easily handle 90 PSI, but you always want the compressor to supply more flow than needed. Pro Tip: Always respect a PSI rating. If you don't supply enough air volume, the tool won't operate correctly.
