RCD

Reverse Circulation Drilling(RCD), also known as airlifting, is effective drilling the 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 are then flushed out through the drill pipe into setting tanks.

Using RCD Rings is highly efficient, safe, and an environmentally friendly solution for drilling large diameters and deep depths. If you fall into one of the following conditions, RCD is the best solution to deal with it.

RCD Feature

  • Large Diameter (bigger than 800mm)

  • Deep Depth (longer than 50m)

  • Hard Rock Drilling (75MPa ~ 250MPa)

  • Bore Piling in Marine Condition

RCD SYSTEM

R.C.D(Reverse Circulation Drilling) System, also known as air-lift is that compressed air is injected into the drill pipe below water level just above the drill bit.

Working with R.C.D system is the highly efficient, safe, and environmentally friendly solution for large diameter and depth.
