Corrosion & Erosion
• Compressor blade rubbing and damage can lead
to loss of eciency and potential catastrophic
failures
• Tip damage may be signicant before serious
vibration damage is noted
• RVI can allow rapid, recordable assessment of
compressor blade condition for evaluation by
experts in remote locations
• See pages 7 - 8 for general description
• Many refractory lining conditions can not be
evaluated by UT or RT
• Manual inspection requires staging, scaolding
and proper conned space entry precautions
• RVI can be used to obtain refractory condition
assessment to prioritize internal inspection and
repair execution to expedite turnaround resources
• See pages 7 - 8 for general description
• Flow-assisted corrosion can occur in all piping that
contains water and water/steam mixtures
• Single liquid phase or dual phase (wet steam) as
shown below can cause severe local metal wast-
age
• Water treatment, design and metallurgy can help
prevent for damage
• Digital radiography can be used for volumetric
examination of specic suspect locations
• See pages 11 - 12 for general description
• High-pressure steam pipe may be exposed to
stresses above design and suer high-temperature
creep damage causing industry incidents with
multiple fatalities and major consequences
• Field metallographic replication (FMR), magnetic
particle testing can only detect creep damage on
outer surface, not a volumetric assessment
• Phase Array can easily be eld deployed to investi-
gate volumetric creep damage in areas of concern
in steam pipes
• See page 9 - 10 for general description
• Carbon steel tubes can be inspected by eddy
current techniques
• RVI can be rapidly used to assess specic tube
conditions for assistance in run-replace decisions
• Tubes can be accessed with minimum preparation
for fast evaluation of tube condition
• See pages 7 - 8 and 13 for general description
• Greatly enhance weld inspection and aw sizing
with digital radiography
• Digital radiography is both qualitative and quanti-
tative
• Digital radiography produces fast scanning and
can go through insulation
• See pages 11 - 12 for general description

Carbon steel piping has failed catastrophically from FAC Elevated temperature damage can occur with increasing
age and operation severity
Air n heat exchanger tube damage can cause signicant
operational problems
Tip damage (rubbing) can be identied by vibration analy-
sis and monitored o line with RVI
Refractory damage can be unexpected and lead to signi-
