Abstract
During a routine plant outage, ID surface cracks were found on the two heads of a secondary superheater outlet header (SSHOH). The continued service of the SSHOH was dependent on a postmortem metallurgical assessment performed on the defective heads. The assessment techniques included visual and optical examination, oxide-scale crack dating, hardness measurement, materials identification, and multiple-heat parametric remaining creep life estimation. The assessment indicated that the ID surface cracks were formed at the very early stage of the header service, and the continued service of the header would not be compromised.
