Effective corrosion control depends first on the availability of that basic information which adequately defines the problem, i.e., where are equipment failures occurring? What equipment is failing and what service is it in? What integral part of the equipment failed and in what manner did it fail? What was the cause of failure? and what did the failure cost? Obtaining such information in an accurate and timely manner, converting the raw data into a useful summary form, distributing prepared summary reports to responsible field supervisors, and subsequently utilizing reported failure data to either revise or supplement mitigation programs are each essential interim achievements which collectively accomplish the real objective-effective corrosion control. The corrosion engineer uses many technological tools in reaching this objective. One such tool which has been effectively utilized in recent years is electronic data processing.
