Boilers, Headers, Steam lines, Turbines, Feedwater Heaters and Condensers are the main components inspected in a non-nuclear power plant.
The reason for inspection depends on the component and its effect on plant operation:
• Boiler tubes and feedwater heater tubes are inspected to avoid forced outages.
• Turbine component inspections are done for safety and operational reasons.
• Steam lines are inspected for safety reasons.
• Condenser tube inspections are primarily done to assess condition for replacement decisions.
Appropriate selection and application of NDT techniques are key to the inspection of power plants.
