Turbine Closure System


Square Drive Hydraulic Torque Wrench

At Tritorc, we understand that efficiency and safety are paramount during turbine maintenance and assembly. Traditional turbine closure methods are often hampered by high labour, time consumption, and hazards. Our advanced Turbine Closure System addresses these challenges by employing hydraulic technology to achieve rapid, safe, and consistent casing closures on industrial turbines.

  • Each operation typically cuts down time-bound-closure reducing tops-on/tops-off time by up to 6 hours, saving over a day of total maintenance per turbine.
  • Closes turbine casings hydraulically that eliminates the need to heat studs avoiding burn injuries, other electrical hazards and time loss.
  • Enables accurate closure by integrated zero-gap monitoring between casings continuously, ensuring uniform tightening without overloading.
  • Ergonomic components and step-by-step process make straightforward deployment minimizing manual intervention and saves manpower.
  • Supports ultrasonic bolt elongation measurement methods to ensure precise bolt stretch in critical coupling applications, increasing joint integrity and longevity.
