Corrosion & Erosion
19
• Insulation and reproong can accumulate
moisture and cause accelerated corrosion
• Breaches of weather jacketing increases with age
and mechanical damage
• Extensive stripping and abatement needed for
visual testing and ultrasonic testing
• Digital X-ray can give general condition a specic
thickness in recordable format for prioritization of
additional inspection/remediation can be scheduled.
• See pages 11 - 12 for general description
• Heat exchanger tube problems can cause unit
outages and environmental impact
• Damage can occur suddenly (titanium tube
support plate wear after 2 weeks of above design
ow conditions) or longer term
• RVI can provide internal condition. Leak testing
does not provide volumetric assessement
• ET is preferred method of tube inspection for non-
ferrous alloys
• See page 13 for general description
• Hydrogen damage can be caused by condenser in
leakage and failures can lead to unit outages
• External UT/EMAT scanning can be used to identify
suspected areas of wall loss
• RVI can rapidly conrm external inspections for
exact location and severity of boiler tubes for ID
damage
• See pages 7 - 8 for general description
Corrosion Under Insulation/Fireproofing
Radiographic Testing (RT)
Heat Exchanger Damage
Eddy Current Testing (ET)
Boiler Tube Hydrogen Damage
Remote Visual Inspection (RVI)
Industrial environments will promote signicant corrosion
of carbon steel piping components
Heat exchanger tubing can suer specic damage that
can be precisely qualied by ET
Localized corrosion damage in carbon steel can be con-
rmed using visual methods
