HF Unit Flange Face Corrosion - Corrosion Inspection
- Hydrofluoric (HF) unit flange integrity must be assessed according to the American Petroleum Institute (API 751).
- Manual flange opening and inspection nearly as costly as outright replacement.
- Non-destructive testing (NDT) phased array ultrasonic (PAUT) imaging can significantly enhance detection and sizing of flange face corrosion damage for replacement prioritization for turnaround
- Proven to be accurate and cost effective over conventional inspection methodologies .
