NACE Recommended Practice RP-01-69 contains criteria for the cathodic protection of steel structures in natural soil and water environments and there criteria have been widely accepted both by the owners of cathodically protected structures and by cathodic protection practitioners. Despite this, it has become increasingly […]

External corrosion of iron watermains has been a problem for municipalities for over 100 years. The three main causes of corrosion, in a historical context are: stray currents from electrified transit systems dissimilar soils galvanic corrosion All of these causes remain with us today, although […]
