Remote Visual Inspection (RVI)
Method Overview
High-definition internal visual assessment of boilers, turbines, and pipes using robotic crawlers and videoborescopes.
Core Method Specifications
Target Applications & Governing Standards
2 Scopes ConfiguredMethod Limitations & Operational Boundary Conditions
Critical physics limits, thermal envelopes, blind spots, and ASME Sec V / API procedural boundaries for RVI.
CCD/CMOS video camera chips produce severe color noise and thermal pixel burnout above 60°C.
Minimum optical focal distance is 3 mm to 5 mm from lens
None
Requires direct optical line of sight; 4-way probe tip articulation (up to 160° bend) overcomes internal pipe elbows
- •Internal subsurface cracks (zero visibility beneath surface oxide layers)
- •Lens fogging, oil contamination, or condensation completely blinding the optical view
Lighting glare and specular LED reflection hot spots mimicking cracks or through-wall pinholes
Measure quantitative remaining wall thickness inside tubes where RVI only sees surface discoloration
Electromagnetic crack detection under internal deposits and scale
