Infrastructure Integrity Assessment and Corrosion Control

This presentation identifies the causes of corrosion and methods of mitigation as they apply to buried and above grade operating infrastructure, such as water, wastewater, fuels, reinforced concrete structures and others.  Both atmospheric and submerged corrosion exposures and assessment methodologes will be discussed.

Ageing infrastructure operating the United States will be faced with many issues relative to infrastructure installation, upgrading and replacement.  Of concern is system integrity to minimize service disruptions and the risk of environmental contamination.  Costs associated with  system infrastructure are very high, and monies need to be expended prudently.  Understanding infrastructure condition is an important part of the overall Infrastructure Master Plan.

Much of the existing infrastructure is in good condition and with modification could be upgraded to provide many more years of reliable service.  This presentation will discuss several of the corrosion engineering studies and analyses that can be employed to define the condition of the infrastructure of concern.  By understanding the current infrastructure condition, defining the corrosion mechanisms, delineating corrosion rates and understanding the environment corrosivity, projected life calculations can then be made.  These studies then develop infrastructure life extension options and life cycle costs for economic analysis.
