Wide range of heat resistance, from -196 C to 650 C, delivering flexibility for operators within a single productīuilt on fiber-reinforced, single-component, inert modified inorganic copolymer technology, exhibiting a unique resistance to micro-cracking, minimizing maintenanceĬomplies with NACE SP0198: 2017 categories SS-5, CS-6 and CS-8Įxtensively tested, both by an independent test house and Hempel, offering proven performance Working closely with your coatings manufacturer to identify solutions that suit your precise needs can provide long-term protection from the harmful effects of the environment - including corrosion that lies beneath insulation. While there is continued uncertainty in the energy markets, it is vital for asset owners to maximize their operational efficiency and minimize downtime. The flexibility and simplicity it offers are important considerations for protecting such complex assets and infrastructure. Versiline CUI 56990 is developed for resistance against temperatures of between -196 and 650 C, making it suitable for almost all oil, gas and petrochemical processing and storage facilities, including offshore floating facilities and assets in harsh environments. Based on fiber-reinforced, single-component, inert modified inorganic copolymer technology, the solution has demonstrated excellent resistance to CUI and exhibits a unique resistance to micro-cracking at elevated temperatures. This means less maintenance is required and assets are protected longer.
To deliver optimum protection and combat CUI, we recommend our Versiline CUI 56990 paint solution. We at Hempel - a coatings manufacturer that has developed protective paints for more than 100 years - understand CUI and the challenges associated with it. While there are many variations in the coatings designed to protection against CUI, three key systems are most commonly used: epoxy/epoxy phenolics, thin film silicones and zinc silicates. The main reasons for coatings failure are poor application, application of an incorrectly specified product or, more rarely, use of a defective product. This makes preventing CUI across an asset and specifying a coatings solution to meet the precise needs of each piece of equipment a challenging process. Temperatures can vary considerably across the fundamental parts of each refinery, or adjoining processing and distribution infrastructure, and must be accounted for separately. It makes sound business sense to protect the areas prone to CUI from the outset and apply an advanced protective coating specifically designed to combat the threat.ĬUI generally occurs in temperatures between 50 and 175 degrees Celsius, but in high relative humidity, it can also be found in lower temperatures - the so-called “sweating” pipe syndrome. If undetected, CUI will continue to erode the underlying material, often resulting in dangerous, costly and irreversible damage to assets and the businesses that rely upon them. CUI occurs when moisture becomes trapped between insulating materials and the pipework, ductwork, valves and other key external equipment vital to the operation of refineries, petrochemical plants and other processing and storage facilities. Corrosion under insulation (CUI) is the fundamental cause of a wide range of mechanical, structural and safety problems across the chemical and processing industries - and it is characteristically difficult to detect.
