Corrosion & Erosion
• Compressor blade rubbing and damage can lead
to loss of eciency and potential catastrophic
failures
• Tip damage may be signicant 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, scaolding
and proper conned 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
• 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
Compressor Blade Damage
Remote Visual Inspection (RVI)
Refractory Vessel Damage
Remote Visual Inspection (RVI)
Weld Heat-Affected-Zone Inspection
Radiographic Testing (CR & DR)
Tip damage (rubbing) can be identied by vibration analy-
sis and monitored o line with RVI
Refractory damage can be unexpected and lead to signi-
cant turnaround repair
Weld defects can cause signicant equipment inspection
