Corrosion margin is not the thickness of corrosion that is permitted; it is determined based on the design service life of the equipment and the corrosion rate or abrasion rate of the medium on the metal material. Whether the equipment can still be used depends on the results obtained from the calculations; this thickness is often much lower than the nominal thickness minus the corrosion allowance. \"Dirt margin\" is a term you invented yourself; scaling is not allowed in many cases, as it increases the risks associated with the equipment.
