23 - Corrosion maintenance and monitoring

Abstract

This chapter aims to cover the corrosion monitoring method to control and prevent corrosion. Corrosion causes pipes, tanks, steel, and other structures to corrode, as it is already a well-known challenge. It has severe economic and other consequences. As a result, corrosion management must be prioritized both during the design process and during the operating period. Whenever a structure, a plant, or any type of equipment is placed into service, it requires regular maintenance in order to operate effectively and reliably. This is especially true for aging systems and buildings, since many of them may continue to function much beyond their initial design life. The level of damage caused by corrosion can be widely predicted and analyzed with the aid of various corrosion inspection and monitoring techniques. It is important to carry out corrosion inspections and monitoring to assess the state of the system, as well as the effectiveness of corrosion management and maintenance actions. Corrosion monitoring encompasses a variety of methodologies, ranging from basic coupon exposure to automated sensor systems for smart structures. The knowledge offered has benefited the development and execution of effective corrosion-related loss-reduction solutions.
