Outline of this presentation
- NBS/NIST 1910-1945 buried-pipe experiments.
- What (little) we know about factors that influence the corrosion rate in the field.
- Theory of diffusion-limited corrosion (we are talking about pitting)
- Survival functions for buried steel pipe.
- Survival functions for above-ground atmospheric storage tanks.
- More and better data is needed.▫ A protocol for tank-bottom inspections and measurements
▫ Standardized definitions of corrosion measures (pit depth, remainingthickness, …)
▫ A standardized suite of soil measurements (resistivity, pH, … ) ▫ Cathodic protection record (percent time in operation, …)
