Industrial assets operating at 140 °F or above may be thermally insulated to prevent plant operators and personnel from experiencing skin burns after accidental touches. Insulation, however, increases the risk of the underlying substrate of suffering from corrosion. Typical insulating systems should consist of three components for a comprehensive and effective insulation strategy: high quality corrosion resistance coatings, absorbent insulation materials, and both effective and durable weather barrier or jacketing.
Industrial assets operating at 140 °F or above may be thermally insulated to prevent plant operators and personnel from experiencing skin burns after accidental touches. Insulation, however, increases the risk of the underlying substrate of suffering from corrosion. Typical insulating systems should consist of three components for a comprehensive and effective insulation strategy: high quality corrosion resistance coatings, absorbent insulation materials, and both effective and durable weather barrier or jacketing. Another alternative is the use of insulating organic coating systems which can provide personnel protection and corrosion resistance. This paper introduces a novel, two-component, solvent-free modified epoxy phenol Novolac resin-based polymeric closed-cell foam for corrosion protection combined with thermal and cool-to-touch insulating properties. Design considerations of such a material, fitness-for-service testing and results are presented. Potential application areas and benefits including ease of use, worksite personnel and corrosion under insulation protection are also discussed.
Corrosion Under Insulation (CUI) is a very serious problem impacting the oil and gas, petrochemical, power and heavy industries. Due to the high costs associated with CUI, many industries have begun abandoning conventional jacket insulation. Recent advancements in trade association standards have helped engineers select, apply and inspect different types of insulative coatings in lieu of conventional jacket insulation.

The use of duplex coating systems (hot dip galvanizing or thermal spray coating with one or more liquid-applied coatings) for long term protection of structural steel is becoming more mainstream in many industries. This paper describes the advantages of employing duplex coating systems as well as some important considerations for designers prior to specifying their use. It also highlights an ongoing initiative to help agencies more efficiently and effectively use duplex coatings on steel bridges by developing guidelines, standards, and other materials.
The author will present on the various generic coatings technologies available for lining concrete and discuss the advantages and disadvantages of each one. Discussion will include epoxy, polyurethane and polyurea technologies. The goal of the presentation will be to provide some guidance to the attendees on when is the right application to select each technology as part of a specification.
