The following criteria are used for the recommended predictive models:
- Validation against short term and long term corrosion data
- Dependency of model parameters to relevant physiochemical properties
Using our unique algorithms developed by expert corrosion engineers, the soil around a buried metallic asset is assigned a soil corrosivity (SC) rating that is based on a number of parameters including soil resistivity, pH, chlorides, sulfates, and linear resistance polarization corrosion data, These ratings identify high soil corosivity areas where assets are located and, based on these ratings, decisions for inspection frequency, prioritization, and long term planning can be made with confidence. This approach is what distinguished us from our competition.
