Insulation Innovation Blog

Traditional materials of the insulation world, such as fiberglass and polyisocyanurate insulation are being pushed aside as they make way for a more natural and sustainable material, mineral wool.

Pipe and tank insulation is a semi-rigid wrap designed to insulate large piping, round duct and other curved surfaces, such as pipes with tracing lines, most fittings and other irregular shapes. Tank wraps are used extensively in industrial insulation applications to insulate horizontal or vertical tanks, vessels and round ducts. The two primary insulation materials used for pipe and tank wraps are either mineral wool or fiberglass.

Recently we discussed the basics of corrosion under insulation. CUI is a blanket term that refers to several different types of corrosion processes. Based on how a part is used and what conditions it’s exposed to, the kind of corrosion that develops may differ.

Recently discussed was the problem of corrosion under insulation and something that goes hand in hand with CUI is high-temp coatings. A large number of industrial processes operate in very aggressive environments characterized by high-temperature, which induces corrosion. 

Corrosion under insulation (CUI) is a severe form of localized external corrosion that occurs in carbon and low alloy steel equipment that has been insulated. 

CUI itself is most commonly galvanic, chloride, acidic or alkaline corrosion. If undetected, the results can lead to leaks and the shutdown of a process unit or an entire facility, causing a war against corrosion!
