Heat exchanger inspection

Advanced Possibilities of Documentation and Avoidance of Misinterpretation of Conventional Documentations

   
 
The exact documentation of the defect position enables the analyses of damage progress that are not possible with conventional measuring and documentation methods (see picture), since these still depend on the comparison of the maximum result of a tube.
   
In order to better demonstrate these facts that can partially be surveyed in a bad way, we revert to position-based defect result documentations.

In this case the length positions and results (right side of picture) refer to the outside tube layer (in the left part of the picture). The indications being each in the upper part describe the current results, the ones in the lower part the reference results of a previous inspection.

Thus this combined presentation allows a quick overview over the grade of the damage progress..
