Summary
A gas export pipeline tie-in spool flange failed after severe corrosion of carbon steel lacking the specified corrosion-resistant cladding. The alert examines material traceability and quality-control failures, misinterpreted inline inspection data and incorrect defect location reporting. Lessons address preserved identification, consideration of positive material identification and diverse integrity inspection measures.
