Sherwin-Williams’ launches advanced energy barrier prevention system, Heat-Flex, for the elimination of corrosion under insulation (CUI).
Mineral-based insulation is traditionally used on storage tanks, process vessels and piping to retain heat, however CUI can occur when water penetrates the insulation and is trapped against the metal product. As Heat-Flex, is a sprayed-on coating, rather than separate insulation, water cannot be trapped, eliminating CUI possibility.
This spray can extend the lifespan of steel products, minimising production and installation environmental costs. Heat-Flex retains operating temperatures of up to 177℃, with excursions to 204℃.
Neil Wilds, global product director – CUI, at Sherwin-Williams Protective & Marine, says: ‘Corrosion under insulation requires the presence of insulation. By removing this from an asset and applying the thermal insulative coating in its place, there is no longer any physical system under which corrosion under insulation could occur. Therefore, the corrosion under insulation is eliminated by default. We’re kissing both insulation and CUI goodbye.’
