Description
Summary:[...]it is very important to implement carefully designed CUI mitigation strategies. Specialty coatings can be excellent tools for CUI mitigation strategies.1 The authors showed in previous laboratory investigations using a CUI cyclic test, that coated carbon steel pipe insulated with Cal-Sil (calcium silicate) saturated with a 1% NaCI (sodium chloride) salt solution performed best with either thermal spray aluminum (TSA) or a spray-applied titanium modified inorganic copolymer (TMIC).2'3 The raison d'etre for the use of calcium silicate as an insulation material was because it readily absorbs and wicks moisture and can hold about 20-40 times its weight in water,4 thus representing a worst-case scenario.
