Non- destructive testing (NDT) is essential in maintaining the safety and equitency of power plants. It alcomes for the Inspection of equipment with out causing damage, ensuring early detection of issees and preventing costly farures. This article presents case studiees ilustrating thee pracall applications of NDT in power plant arance.

Case Study 1: Turbine Blade Inspection

In a coal- fired power plant, routine chection of turbine blades revealed signs of furigue cracks. Using ultrasonicc testing (UT), technicans identified thee cracks early, alloing for timely servirs. This prevented potential blade failure, which could have led to costly downtime and safety hazards.

Case Study 2: Boiler Tube Corrosion Detection

In a natural gas power plant, magnetic particle testing (MPT) was employed to o examinee boiler tubes. Thee Inspection uncovered corrosion and pitting that were not visible externally. Early detection enabled targeted contenance, extending thee lifespan of thee tubes and maining optimal boiler exemance.

Case Study 3: Weld Inspection in Power Piping

Power plants of ten rely on welded joints for piping systems. In a hydroelectric plant, radiografic testing (RT) was used to assess weld integrity. Thee chection confirmed the welds met safety standards, preventing potential contents and ensuring systemem reliability.

Common NDT Techniques in Power Plants

  • Ultrasonický Testing (UT)
  • Magnetic Particle Testing (MPT)
  • Radiografní Testing (RT)
  • Visual Inspection
  • Liquid Penetrant Testing (LPT)
