Tongue Seals
Crux Tongue Seals have a proven record of reliability and are used on Offshore Wind Farms to support grout between the pre-installed monopile and the transition piece.
Tongue Seals for Offshore Wind Turbines
The working principle behind tongue seals for offshore wind turbine structures is:
- Tongue Seals are fitted prior to the pile or transition piece placed in position.
- The seal can be used where the transition piece is inside or outside the pile.
- The seal works by self-activating as grout pressure is applied.
Crux Tongue Seals for Drilled Piles
The Tongue Seal supports grout between a pile and a pile sleeve on structures where the piles are installed by drilling. The seal is fitted on the pile prior to the pile being lowered into pre-drilled hole and 'self activates' as grout is injected. Two seals can be used for greater pressure head. Tongue Seals can also be fitted to offshore wind farm structures.
