An industry challenge: Corrosion Under Insulation (CUI)
Corrosion is present in many aspects of life. According to the World Corrosion Organization, the annual cost of corrosion worldwide is over 3% of the world’s GDP. Corrosion is a major challenge in the Oil & Gas Industry, where it is often presented in the form of Corrosion Under Insulation (CUI). CUI is difficult to detect, the corrosion processes occur hidden beneath the insulation and are often discovered when major damage has occurred already. CUI leads to billions of dollars in repair, maintenance and stand-still time costs for the industry and places risk on safety and environment.
Corrosion 2016 Conference & Exposition
World's largest dedicated corrosion event, Corrosion 2016 Conference & Expo, will bring together once more corrosion professionals and decision makers from across the world. Over 340 exhibitors and 5,500 corrosion engineers, scientists, researchers, technicians, asset owners, inspectors, and other professionals from around 70 countries will share their methods and stories of failure and success, incidents and case studies, through a program packed with technical and educational sessions from 15 industry and technology tracks. The event will take place from March 6-10, 2016 in the Vancouver Convention Centre, Vancouver (Canada).

Armacell at Corrosion 2016
Armacell Engineered Systems, manufacturer and service supplier of industrial insulation solutions, will present its latest developments in Armaflex and ArmaSound thermal and acoustic insulation systems at Corrosion 2016 (booth 2146).
The insulation systems are an important factor in the process of mitigating CUI, as proven in a recent test conducted by TNO/Endures (the Netherlands), where Armaflex insulation systems were submitted to an aggressive environment, ideal for corrosion development. The outcome of the test concluded that the insulation systems effectively inhibit the spread of corrosion under insulation, confirming the excellent results which have been achieved with Armaflex Industrial insulation materials installed across the world for decades. These lightweight, closed-cell FEF insulation materials with built-in vapour barrier combine low thermal conductivity and a high resistance to water-vapour transmission. They are an important part in preventive maintenance strategies and in providing plant components with improved overall safety and long-term protection against condensation, energy losses and risk of CUI.
Exploring the impact of FEF insulation on corrosion mitigation
Through years of study, trial and error, a deep understanding has been gathered on the behaviour of piping materials and coatings with regards to corrosion development, and a major focus has been placed on these components when designing strategies to reduce risk of corrosion. However, the industry has recognized that the choice of insulation material also has a high influence in the process of mitigating corrosion and, more specifically, CUI: the choice of material decides whether the insulation minimises the risk of corrosion - or favours corrosion processes.
To increase the level of understanding on how different insulation systems (Elastomers and other non-metallic materials) work in regards to moisture penetration and mitigation of corrosion under insulation, and eventually explore harmonisation of test methods and development of standards, a technical work group (TG086) has been created by NACE. The working group will have its first meeting on March 7, during Corrosion 2016.
Dr. Mark Swift, Technical Director of Armacell Engineered Systems, has been invited to present in a 20-minute session the benefits of flexible elastomeric foam (FEF) insulation systems. The session will share the methods and results of a "spread of corrosion assessment test" conducted by TNO/Endures, which concluded that the closed cell structure of the applied FEF insulation system and the method of its application effectively mitigated the spread of corrosion.
About NACE Corrosion
Corrosion 2016 is an initiative of NACE International, the National Association of Corrosion Engineers. NACE was founded in 1943 by a group of North-American corrosion engineers from the piping industry with the mission to protect people, assets and the environment from corrosion. Today, NACE International serves nearly 36,000+ members in 130 countries and is recognized globally as the premier authority for corrosion control solutions. The organization offers technical training and certification programs, conferences, industry standards, publications and more. NACE International is headquartered in Houston, Texas, with offices on 4 continents.
About Dr. Mark Swift
Dr. Mark Swift graduated in 1994 with an Honours degree in ‘environmental management and technology’ from the University of Bradford in the United Kingdom. Specialising in environmental acoustics during the latter stages of his degree, he went on to receive a Ph.D. in ‘acoustic and physical properties of poro-elastic media’ in 2000.
Following a successful post-doctoral and consultancy position at Bradford, he joined Armacell in 2003. Since joining Armacell, he has been actively involved in developing new products and markets specifically in the area of acoustics and industrial insulation. Dr. Swift is now Technical Director for Armacell’s Engineered Systems division which is responsible for the company’s Oil and Gas initiatives.
