Corrosion Mapping (CM) Services
Corrosion Mapping provides detailed thickness maps of equipment walls to assess corrosion damage and predict remaining life.
What is Corrosion Mapping?
Corrosion Mapping is a specialized application of ultrasonic testing that creates detailed wall thickness maps of equipment and piping to assess the extent and severity of corrosion damage. Using encoded scanning systems, corrosion mapping produces color-coded C-scan images that clearly show areas of wall loss, enabling accurate remaining life calculations and maintenance planning.
How CM Works
Encoded UT scanning creates position-correlated data
C-scan display shows thickness as color-coded map
Statistical analysis determines corrosion rates
Comparison with previous scans tracks progression
Applications of Corrosion Mapping
Advantages
- Comprehensive area coverage
- Permanent digital records for trending
- Accurate remaining life calculations
- Color-coded visual display
- Identifies localized corrosion patterns
- Supports risk-based inspection programs
Limitations
- Surface access and preparation required
- Slower than spot readings
- Equipment cost higher than manual UT
- Requires trained operators
- Couplant management on vertical surfaces
