Repair of a corroded vessel skirt subjected to an overturning moment

A parametric finite element model was used to determine the most economical solution

A? reactor support skirt in a petroleum refinery was subjected to severe corrosion under insulation (CUI). Investigation into the causes revealed that this corrosion resulted from water being trapped under the fireproofing. It was discovered that the extent of CUI affected the circumference of the entire skirt. The remaining thickness in the affected areas of the skirt ranged from 0.18 in. to 0.3 in. (original thicknesses were 0.3125 in. and 0.375 in.). This article describes the procedures used to analyze and repair a corroded vessel skirt that is subjected to an overturning moment. This analysis is accomplished in accordance with the 2005 National Building Code of Canada1 (NBCC) and ASME
