Summarizes the work of five investigative NACE work groups formed to study nondestructive testing methods, unit operation and water chemistry, unit fabrication and repair, failure analysis, and failure mechanism and corrosion data. Addresses procedures for inspection of deaerator heater and water storage vessel welds, including reinspection criteria and qualification of personal; factors influencing boiler feedwater deaerator cracking based on literature references and case history analysis; standardized nomenclature of deaerator vessel welds and cracking; guidelines for materials, design, fabrication, inspection and acceptance criteria for new deaerator vessels, and for repair of existing deaerator vessels; and operational and water chemistry parameters that may influence deaerator deterioration.
