An Estimate of Corrosion Losses to Underground Cables and Pipe Lines in Japan

An estimate was made of corrosion losses to underground cables and pipe lines in Japan. It was found that such losses over the past few years averaged approximately $200,000 annually. This figure was arrived at by making use of such factors as total length of installations, number of failures per year caused by chemical corrosion, number of failures per year caused by electrolytic corrosion, annual expenditures necessary for replacements and repairs, average repair expenditure per failure, and rate of failure due to corrosion per 100 km year. 1.2.2
