Case - remaining life under corrosion

The corrosion, internal or external, is not always linear or equal for each component of a pressure vessel or piping. The assessment of the remaining life is not straight forward and requires some iteration. Red-Bag uses the in-house developed PCALC application with the individual calculation to create a custom made corrosion assessment tool. The corrosion will progress in time. Every time step the applicable corrosion is determined and all the required calculations are executed. The steps are continued until the first component fails. This will determine the remaining life of the equipment or piping. (Ineos)
