Best Quality and Frequency of Thickness
Measurements
Corrosion Awareness Day 2018
• Fast response to corrosion and/or erosion
– Excellent measurement repeatability affords detection and measurement of ≈ 10 microns of metal wall loss
– Regular data delivery (e.g. every 12 hours) allows detection of corrosion or erosion events within days
-
13
Significant Enhancement Over Traditional
Manual Inspection
Corrosion Awareness Day 2018
• Permasense: measurements every 12 hours within +/- 10 microns variation; catch onset of corrosion events within days
• Manual UT inspection: years between measurements with +/- 0.5-1.0 mm variation; corrosion rate calculation not possible, corrosion events missed

Adaptive Cross Correlation, AXC
• Adaptive Cross Correlation, AXC
– Correlation where signal matches previous backwall
signal most closely
– Roughness scattering effect is overcome
• Permasense Shape Indicator, PSI
– Correlation to previous backwall signal introduces
backwall reflection and morphology change indicator
– Early warning of the onset of localised corrosion / pitting
