Abstract

Tubular heat exchangers (HE) are common and often physically large in power and process industries, e.g. in steam generators, boilers, preheaters, furnaces and many other essential applications to transfer heat of process fluids. HE performance is important for managing the overall efficiency, economy, life and predictable maintainability of the process & plant: typical investment cycle ~ 20-60 years, opportunity for planned inspections and maintenance once every ~ 1-6 years. Intervening damage or failures will reduce equipment life and increase the risk of unplanned shutdown/maintenance, business interruptions and high cost recovery. Systematic countermeasures include risk-based methods, such as risk-based inspections (RBI).
