Bob rasooli solves an api 570 piping inspctor exam problem to calculate short term corrosion rate, long term corrosion rate, remaining life and determine ins. Erosion corrosion and corrosion under insulation. Dividing the corrosion rate in g/ (cm 2 ·day) by the density gives the depth of corrosion per day.
Assuming there is some coating still present on the steel you can estimate the remaining life of the coating using published data, for example iso9223/9224. Api 570, piping inspection code: For new vessel or for a vessel for which service conditions are being changed, the remaining life calculation methods is used to determine the vessel’s probable corrosion rate.
