To perform a performance analysis for a gas piping in a composite and comprehensive manner by comprehensively analyzing data regarding failure density and surface roughness digitized by being passed through each of optical microscope inspection, failed structure and component analysis and surface treatment analysis so as to set a control reference.
A test piece piping to be analyzed is prepared (S1) and the test piece piping is cut into sizes and formed for easy analysis (S2). The state of the cut test piece and a failure density are measured by an optical microscope (S3) and in order to understand the pattern and components of the failed surface of the test piece impossible to be measured by the optical microscope and the forms of surface particles, the structure and components of the failed portion are analyzed (S4). Further, components are analyzed according to the thickness and depth of a surface treating tank (S5), data regarding a failure density and surface roughness digitized after being passed through these stages is comprehensively analyzed and a tube control reference is set. Thus, performance analysis for the gas piping is executed in a composite and comprehensive manner.
