TURBINE CYLINDER CLOSURE SYSTEM - HOW IT WORKS
INTEGRA's Turbine Cylinder Closure System uses a series of Hydraulic Nuts connected to high pressure hoses and an air driven hydraulic pump unit to create a closed hydraulic system. By applying hydraulic pressure to the nut body, we generate a load proportional to the annular area of the piston, stretching the service stud and allowing the piston to move out of the body. The locking collar is then screwed tight against the nut body, retaining the load when the hydraulic pressure is released.

Once complete, the hydraulic system is depressurized and disconnected and the BlackHawk™ Hydraulic nuts are removed.

This simple, accurate and flexible system means rotor clearance checks can be completed in a fifth of the time compared with conventional bolt heating methods - translating into time you can be back up and running.
