Corrosion Allowance
Additional wall thickness specified in design to account for anticipated corrosion during the service life of a component. Components are fabricated at nominal thickness plus corrosion allowance. During inspection, actual thickness is compared to the nominal value; when actual thickness decreases below nominal thickness minus corrosion allowance, the component is considered unfit for continued service. Corrosion allowance depends on operating environment and expected service life.
