Abstract

A system and method for displaying inspection data collected from a furnace is disclosed. The system comprises a storage device for storing the inspection data. The system also comprises a computer programmed to partition the inspection data at a plurality of data markers so as to correlate the inspection data to the physical geometry of the furnace. Each of the data markers identifies the location of a physical feature of the furnace (such as a bend, an external raised surface, cross-over piping, a thermal well, a weld, a flange, a schedule change and/or a diameter change). Preferably, the computer is also programmed to generate a display of the partitioned inspection data, wherein the display is a two-dimensional or three-dimensional representation of the tube segments of the furnace. This display may then be used to visually detect problem areas within the furnace. Various exemplary embodiments of the system and associated method are provided.
