28. Monitoring and Inspections

Corrosion of industrial equipment can lead to risk conditions for economic losses and safety of personnel. To minimize that risky, besides the correct selection of material and the use of proper preventative methods, the design of a corrosion monitoring system plays an important role, followed by programmed inspections during operation. The analysis of monitoring and inspection results is also important to plan maintenance activities. This Chapter deals with the selection of the correct monitoring strategy and its application to operating systems: the most common monitoring techniques, as the use of corrosion coupon, electrical probes, linear polarisation resistance, galvanic probes, corrosion potential are presented. A brief outline of the most important non-destructive techniques is also reported.
