Moisture as a cause of CUI

Moisture as a cause of CUI

Andy Hoffman

Moisture is one of the major factors to consider when investigating corrosion under insulation (CUI). Accumulating water within an insulation system can wreak havoc on metal piping, ventilation and other insulated surfaces, originating from a variety of sources, including condensation within the systems, water spray from deluge systems, drift from cooling towers, process leakage or rainfall. But moisture can cause another problem while it goes untreated: a reduction in efficiency.
