During maintenance works at Electric Power Plants borescopes sand videoscopes are used to reduce maintenance costs and avoid outages. Videoscopes can be used in the following areas:
- Steam and gas turbines - turbines are checked for foreign object damage, erosion, burning and cracking. Combustion chambers are inspected for cracks, combustion deposits and burning. Turbine section nozzles and blades are checked for cracks and erosion.
- Heat Exchangers - cooling tubes are checked for scale deposits, corrosion and cracking.
- Boilers are remotely inspected with long videoscopes.
