Boiler Tube Hydrogen Damage - Corrosion Inspection
- Hydrogen damage can be caused by condenser in leakage and failures can lead to unit outages
- Non-destructive testing (NDT) such as external ultrasonic/electromagnetic-acoustic transducers (EMAT) scanning can be used to identify suspected areas of wall loss
- Remote visual inspection (RVI) can rapidly confirm external inspections for exact location and severity of boiler tubes for ID damage
