Corrosion Under Insulation. What causes corrosion under insulation? Corrosion under insulation (CUI) refers to oxidation on the surface of an insulated metal pipe or vessel. The insulation material traps moisture underneath it, causing the metal to be in constant contact with oxygen in the water. This constant contact exacerbates the problem by increasing the corrosion rate. Corrosion under insulation is a hidden phenomenon. For practical reasons, it may not always be possible to apply the best insulation-coating combination or use the most feasible inspection methods. Intruding water is the key problem causing CUI. Corrosion may attack the jacketing, the insulation hardware or the underlying piping or equipment. The corrosion may present itself in one of several different types, such as chloride, galvanic, acidic or alkaline corrosion. By understanding the types of corrosion that may occur under insulation, the proper materials and construction methods can be proactively applied to prevent them. Environmental Conditions Leading to Corrosion Under Insulation: Foreseeing CUI rates is difficult they can be highly localized or somewhat general in nature. Listed below are some of the environmental conditions that lead to higher CUI rates: 1-) Marine environments 2-) Hot or humid environments 3-) Climates with higher rainfall 4-) Steam tracing leaks 5-) Intermittent wet-dry conditions 6-) Contaminants from the insulation or the atmosphere (such as chlorides and sulfides) dissolving in water 7-) Systems that operate below typical atmospheric dew point 8-) Insulation systems that don’t allow moisture drainage 9-) Insulating materials that hold moisture CUI is a threat to many industries. If neglected, it remains hidden under the insulation system and becomes only obvious after severe failures. CUI occurs through penetration of water or moisture and contamination via condensation or external sources (e.g., rain, sprinkler system).CUI can be very localized, with most of the equipment remaining in good condition. #CUI #CorrosionManagement #Learning

good post below about #CUI ?? as batch of potential solutions to combat corrosion under insulation Primo : apply well selected coating system for relevant process service Secundo: use hydrophobic water repellant insulation Terito: Use rubber seals for insulation terminations, spacers , drain & venting plugs Quatro: apply jacketing / cladding with water-shed design ("water deflectors" ), lock forming and industry standard finishing. Use the same material grade for jacketing / cladding as its installation fixings with cold/Cryogenic and acoustic services it is different story (lower CUI risk although ) #corrosionUnderInsualtion #corrosion #insulation #jacketing #cladding #coating #painting #lagging #fabricMaintenance

Today, I came across an interesting insight about corrosion under insulation (CUI) that changed my understanding. Initially, I believed that once materials were insulated, they were fully protected from corrosion—leading to higher efficiency, longer lifespan, and better customer satisfaction in industries. However, I’ve learned that CUI can still occur beneath insulation, posing hidden risks. This shows that even with new inventions or innovations, unforeseen challenges can arise, and it's crucial to address them early on to maximize the benefits. Continuous learning and adapting to these challenges is key to staying ahead!

For insulated tanks, Corrosion Under Insulation is a particular problem at the lower section of?the shell.
Corrosion Under Insulation in Tanks For insulated tanks, Corrosion Under Insulation is a particular problem at the lower section of?the shell, at stiffening rings, on the roof and where there are penetrations through the insulation? weatherproofing. The rate of corrosion is dependent upon water or water vapour penetration?and its retention in the insulation. Metal/ambient temperature, corrosion inhibitors within the?insulating material, and paint coatings under insulation all influence the rate of attack. Good design, material selection, attention to detail and good standards of workmanship are?fundamental in minimising corrosion issues. The use of cellular glass closed cells are recommended?for susceptible areas that include the bottom section of the shell, at secondary wind girders, on?insulation support rings, or locations where water could pool. This is due to the low moisture? retention qualities of the ‘closed cell’. Appropriate adhesives and sealants/mastics should be?selected as the end of their functional life, which may allow water ingress between insulation and?shell, is difficult to detect. Some tank operators prefer to leave the bottom section of the shell un insulated in order to prevent?wicking up action and to allow drainage of any water having entered the insulation at higher?elevation penetration. There is some loss of heat, but a critical part of the tank is readily accessible for inspection, and corrosion degradation is removed in this location. However, the un-insulated part may be affected?by thermal stresses during periods of low ambient temperature. Insulation requirement in this location should therefore be periodically reviewed. #oil #refinery #storage #tanks #terminal #maintenance #inspection #corrosion #insulation #heat #hotprocess #thermal #safety #desing #engineering #oilgas
