Stray-current corrosion is an accelerated form of corrosion caused by externally induced electric current. It can occur in unprotected pipelines and submerged metal structures located near electric power sources or anywhere voltage differences exist. This article describes common scenarios and sources of stray current along with ways to detect it and prevent the type of corrosion it can cause.
