multi technique corrosion monitoring

Multi-technique Approach:

A further important consideration in selecting corrosion monitoring techniques is the relative degrees of accuracy and control that they provide. As already indicated, many corrosion monitoring techniques do not necessarily provide accurate, quantitative corrosion information. A detailed inspection procedure may be required to provide an accurate indication of corrosion damage.

For a high degree of control over corrosion damage, sensitive real time corrosion monitoring techniques are generally required. Operational parameters and corrosion control measures can be adjusted on the basis of the early warning provided by such sensitive techniques, in order to maintain adequate corrosion control.

The degree of accuracy and control afforded by individual corrosion monitoring techniques depends on the form of corrosion, the operating environment, the geometry of a particular corrosion monitoring application and other factors. Accuracy and control rankings may vary on a case by case basis but individual techniques will always tend to be limited in accuracy and/or control. In view of these limitations, it is again advisable to follow a multi-technique approach, to provide adequate overall accuracy and control.
