Korrosjonstillegg

Korrosjonstillegg is a term used in industrial and engineering contexts, particularly in Scandinavia, to refer to an additional cost or allowance that is factored into calculations for materials, equipment, or projects exposed to corrosive environments. This allowance accounts for the anticipated degradation of materials due to chemical or electrochemical reactions over time. The purpose of a korrosjonstillegg is to ensure that the design life and functional integrity of a component or structure are maintained despite the corrosive attack.

When specifying materials, engineers may select a more robust or resistant material to combat corrosion, and the korrosjonstillegg would reflect the increased cost of this superior material. Alternatively, it can represent an additional thickness of material added to compensate for expected material loss over the service life. This approach allows for a longer operational period before replacement or significant maintenance is required. Factors influencing the size of the korrosjonstillegg include the type and concentration of corrosive agents, temperature, humidity, and the specific material being used. Accurately assessing and applying a korrosjonstillegg is crucial for economic viability and safety in environments such as offshore installations, chemical processing plants, and marine structures.
