According to an EPRI (Electric Power Research Institute of the US) study more than half of all unplanned power outages are due to corrosion, which generally corresponds with other studies that half of all failures in industry are corrosion related. Studies in different countries indicate that between 25% to 30% of water supply is lost in the supply chain due to corrosion. The effects of corrosion are well documented, including...
