Chemical Processing Prevent Chemical Corrosion The chemical processing industry is arguably the most damaging environment possible in terms of component corrosion. From strong acids to caustics, the very product itself can lay waste to conventional metals in short time. To ensure chemical process reliability, it is critical that plant designers prevent chemical corrosion in their .
Corrosion in power plants can lead to large financial losses. Use humidity control strategies to prevent many types of corrosion including oxidation, galvanic corrosion and erosion.

Galvanic corrosion is an electrochemical action of two dissimilar metals in the presence of an electrolyte and an electron conductive path (Figure ).A potential difference usually exists when two dissimilar metals are in contact. In such case, corrosion of less resistant metal is increased while corrosion for more resistant metal is reduced; whereas, more active metal acts as an anode (the ...
Corrosion resistance, the ease with which it can be steam cleaned and sterilized, and lack of need for surface coatings has also influenced the use of stainless steel in commercial kitchens and food processing plants.

Galvanic corrosion is an electricalchemical process where one metal is more susceptible to corrosion than another when both metals are linked electrically. Galvanic (also called sacial) anodes utilized to protect steel structures are an example of galvanic corrosion, where the galvanic anode corrodes to protect the structure.
Galvanic Corrosion is a corrosive process that occurs when two different metals come in contact in an electrolytic solution or in certain circumstances that a corrosive reaction takes place. During the process, one grade of metal is active while the other grade is noble.

The majority of the corrosion threats apply to carbon steel, the most commonly used material for upstream oil and gas production systems, structures and components. Threats to other materials are identified. This guide has been prepared to supplement the Energy Institute publication Guidance for corrosion management in oil and
Corrosion can proceed in a general manner (general corrosion) or in a more localized manner (galvanic corrosion, pitting corrosion, formicary corrosion), depending on conditions and the material systems used. Galvanic Corrosion The necessary conditions for galvanic corrosion occur when dissimilar metals, in contact, are exposed to an electrolyte.
One form of localized corrosion is galvanic corrosion. The necessary conditions for galvanic corrosion occur when dissimilar metals, in contact, are exposed to an electrolyte, a substance that is electrically conductive when dissolved in water. The environment creates the electrolytes necessary for general and localized corrosion of materials.
