Why Corrosion Allowance on the Component Properties dialog in AutoPIPE Vessel is grayed out?
The option “Pressure bearing” is not checked. On any component without “pressure bearing”, the corrosion allowance field is disabled. Because AutoPIPE Vessel doesn’t considered corrosion allowance without pressure. A component without pressure is used in specific cases: e.g. a cylindrical shell between two chambers used as a support. This kind of component is like a skirt for which the corrosion is not taken into account.
