Materials - Corrosion and Corrosion Allowance - Pipi

2019-10-6 · Corrosion Allowance general. The corrosion allowance is a measure which is used in the maintenance applications. A corrosion allowance of 3.0 mm means that e.g. a wall thickness without any problem may be decrease with 3.0 mm. Mind you, that does not mean than the minimum wall thickness is achieved and the object has reached its end of life.
