RCD RIG

RCD Rig（Reverse Circulation Drilling Rig）
Reverse Circulation Drilling (RCD), also known as airlifting, is an effective drilling method that exploits compressed air, as it is injected into the drill pipe below water level, to reduce the density of the internal water column and remove slurries through the circulation. The mixture of water, air and cuttings is then flushed out through the drill pipe into settling tanks. Using RCD Rigs is highly efficient, safe, and an environmentally friendly solution for drilling large diameters and deep depths.

RCD Feature
・Large Diameter (longer than 800mm)
・Deep Depth (higher than 50m)
・Hard Rock Drilling (75MPa ~ 250MPa)
・Bore Piling in Marine Condition
