Whitepaper / Cathodic Protection Performance
Soil characteristics and pipeline corrosion are inextricably linked. It’s well known that soil composition, temperature, moisture and concentration of ions can all influence where a buried pipeline corrodes and how fast the corrosion occurs.
But in many cases, soil temperature and moisture can vary significantly throughout the year causing large swings in soil resistivity and the corrosivity of the soil. Unfortunately, many cathodic protection (CP) systems cannot adequately take into account the seasonal variability of soil conditions when setting rectifier voltage output, potentially leaving pipeline assets more vulnerable to corrosion at certain times of the year.
Download our latest whitepaper release “MANAGING SEASONAL EFFECTS ON CATHODIC PROTECTION OPERATION” to learn how a two-stage approach for setting alarm thresholds and leveraging a large data set of RMU measurement data, soil classifiers and data analytics can deliver a powerful tool for optimizing CP monitoring systems to account for seasonal soil variations. Apply to existing RMU devices to predict future conditions—or to new RMU installations to set initial threshold limits that are in line with anticipated seasonal variations and soil classifiers.
