A new Olivier coupling was developed for use on small drilling pipes with a diameter of 133mm – 5” ¼ (219mm – 8″5⁄8) and larger. This for various applications such as FDP, Soilmix, CFA, … This coupling uses the patented bayonet plugs. This ensures that no thread wires are used anywhere.
- Full round coupling (No hex or octagon)
- Slides 500mm (20″) into each other
- Locked with 16 bayonet plugs
- No screw thread
- Inner passage 125mm (5″)
- High-pressure concrete and grout injection (Available with or without rubber seal)
- Plugs completely sealed off from the inside of the drill pipe so no grout can escape
- Coupling has almost the same diameter as the pipe = less wear
- Plugs rounded into the radius of the coupling = less wear
- Always easily detachable: Once the plugs are out, the couplings can be rotated relative to each other
- High drilling torques, axial and radial forces
- Applicable for various techniques:
- FDP
- CFA
- Soilmix
- Geothermal
- …
- Two types of weld connection available
- Couplings available separately and from stock
Olivier couplings are available for pipes from ∅219mm (8″5⁄8) up to ∅508mm (20″)
