Impressed current systems use an outside source of power to drive the current from the anodes to the cathode. This source can be solar power, batteries, DC generators or 60 Hz alternating current (AC) converted to DC via a rectifier or other device. The most common impressed current systems consist of an anode cluster (also called a "ground bed"), which can be in one location or distributed around the protected structure, powered by rectified AC power. |

Sprinkler contractors, facilities managers, and their technical advisors sometimes have to deal with corrosion inside pressurized, water-based, metal fire sprinkler piping systems.
Clarke observed that corrosion causes pinhole leaks as well as insoluble corrosion residue buildup ("obstructive growth") that increases pipe friction losses. Corrosion deterioration was attributed to microorganisms in water, i.e., to microbiologically influenced corrosion (MIC). |

Intergranular corrosion (IGC), also termed intergranular attack (IGA), is a form of corrosion where the boundaries of crystallites of the material are more susceptible to corrosion than their insides. (Cf. transgranular corrosion.) |

Pitting corrosion is a localized form of corrosion by which cavities or "holes" are produced in the material. Pitting is considered to be more dangerous than uniform corrosion damage because it is more difficult to detect, predict and design against. Corrosion products often cover the pits. A small, narrow pit with minimal overall metal loss can lead to the failure of an entire engineering system. Pitting corrosion, which, for example, is almost a common denominator of all types of localized corrosion attack, may assume different shapes. |
