In general, no particularly well-established standards have been in place so far, for the method of evaluating the deteriorated level of pipes and ducts of industrial facilities. For that reason, the evaluation depends upon various studies which are based on the analysis of the residual life, thickness thinning, closure rate, and scale thickness that measure a few specific positions of pipes. It also depends upon the expertise in business operation and the specific techniques conducted by the inspection companies and institutions. This research introduces the concept of measuring units per section and the selection method of measurement points per section. Furthermore, specific methodologies were developed to plan and analyze deterioration level of industrial pipes and ducts by engineers and managers using a section map. Consequently, applying the outcomes from this study to the plant equipment of the incineration facility resulted in saving 42% of the repairing and remodeling cost.

This study introduced deterioration evaluation item and criteria that could be applied to industrial facilities with the most widely used carbon steel pipe installed for ordinary piping (KSD 3507). Experimental industrial pipes were evaluated with pipe sectionalizing method combined with the established evaluation item and criteria to measure and manage semi-continuously for overall piping system. After applying outcomes from this study to a plant of incineration facility, a 42% saving in repairing and remodeling cost was achieved.
