Galvanic corrosion can become evident in numerous places, and some are more critical to plant integrity than others. Supports over or under austenitic stainless-steel piping are critical areas that should be inspected closely for any signs of damage by galvanic corrosion.
The galvanic corrosion of commercially pure titanium coupled with 18.8 stainless steel was studied in various kinds of corrosive media. In reducing acids, although the corrosion potential of titanium itself was in the active range and less noble than that of stainless steel, it was shifted into the passive range by coupling with stainless steel.

The plant will be fitted with a highest-efficiency high-pressure pump unit operating in parallel with a small booster pump. The high-pressure pump will be a piston-type positive displacement unit to increase the pressure from approx. 3 to approx. 60 bars. The pump will be made of homogenous materials to avoid galvanic corrosion, which
Forms of Corrosion General Identified by uniform formation of corrosion products that causes a even thinning of the substrate steel Localized Caused by difference in chemical or physical conditions between adjoining sites Bacterial Caused by the formation of bacteria with an affinity for metals on the surface of the steel Galvanic/Dissimilar Metal
indirect, in that corrosion affects the useful service lives of our possessions, and indirect, in that producers and suppliers of goods and services incur corrosion costs, which they pass on to consumers. Most dangerous of all is corrosion that occurs in major industrial plants, such as electrical power plants or chemical processing plants.

Galvanic corrosion requires a few conditions to occur. First, the two dissimilar metals must be connected to each other so that an electrical current can develop between them. If they are electrically isolated from each other, galvanic corrosion cannot occur. Second, the metals must also be in contact with a corrosive electrolyte solution.

This paper presents a research on the corrosion behavior of Ti-15-3 alloy overlapped with aluminized PVC film in salt spray. It was found that severe corrosion occurred on aluminized PVC film in the coupled regions because of crevice corrosion and/or galvanic corrosion whereas Ti-15-3 alloy in the coupled regions experienced minor corrosion.
In power plants, corrosion is the primary factor leading to costly and critical downtimes. The water-steam circuits in fossil and nuclear power plants are inherently prone to corrosion, as metal components are constantly in contact with water. Measures to monitor or prevent corrosion are crucial in this context.
