Pipeline integrity management approaches for the management of stress corrosion cracking have relied on past experiences in addition to mechanistic considerations.  Recent and current joint industry efforts have produced large quantities of field data, most of which are in agreement with our mechanistic knowledge, but some data reveal new insights.  The effects of field data revelations on mechanistic perceptions of pipeline SCC and laboratory research interpretations are discussed.  Also, implications towards the prediction of in-service performance are addressed.
