Various types of erosion damage have been experienced in chemical industries. However, the environmental conditions in the field are too complicated and complex to correlate the degree and occurrence of erosion damage in actual equipments. Only the past experiences, trouble information from similar plants and continuous inspection at the portions of equipments where erosion is suspected are only information to control and prevent the erosion. In this report, some examples of erosion damages experienced in our plants are described. And non-destructive inspection techniques applied to those erosion damaged irregular area to measure wall losses quantitatively in the fields are shown. Because of the limited reliability of the estimation of quantitative erosion damage from environmental or operational conditions, accurate non-destructive inspection of wall thickness is very important to keep safety of equipments.
