Industrial Applications of Flexible Bolt Heaters
- Turbine Maintenance (Gas & Steam Turbines)
Use Case: Turbine casings are held together with large, high-tension studs.
During overhauls, removing these bolts without damaging the threads is crucial.
● Bolt heaters are inserted during planned shutdowns to expand bolts for safe removal.
● Used in power plants, aviation engine overhaul stations, and marine engine rooms.
● Minimizes mechanical stress on casings. - Petrochemical & Oil Refinery Equipment
Use Case: High-pressure flanges in reactors, columns, and heat exchangers
must be disassembled periodically.
● Flexible bolt heaters help to avoid galling or thread seizure during bolt removal.
● Reduces downtime during scheduled turnarounds.
● Ideal for hazardous areas – can be customized for ATEX zones. - Nuclear & Thermal Power Plants
Use Case: Precise bolt tensioning and detensioning is critical for safety.
● Bolt heating enables even stress distribution and avoids warping of critical flanges.
● Used in nuclear steam generators, pressure vessels, and critical valves. - Heavy Engineering & Manufacturing
Use Case: In shipbuilding, heavy compressors, or mining equipment assembly.
● Bolt heaters are used during pre-heating for bolt insertion – especially where precision
torque and high vibration resistance are needed.
● Prevents cracks and micro-fractures due to over-tightening. - Heavy Engineering & Manufacturing
