Opis:: A long time operation of pipelines can lead to the reduction of their wall thickness. This process is accelerated by high temperature and variable pressure of the transported medium and can finally cause mechanical failures along with leaks and danger of explosion. The aim of this paper is to present a new method for the detection of abraded walls in industrial pipelines using the time-frequency analysis. The results of transient temperature measurements are used for the calculation of the thermal time constants corresponding - as demonstrated - to the pipeline wall thickness.

Opis:: A new software tool for transient thermal analysis based on thermographic measurement of temperature is presented. In the proposed approach, temperature change after applying or removing power can be measured by a thermal camera or any contact temperature sensor. The software calculates thermal impedance in frequency domain and represents it in the form of the Nyquist plot. In addition, thermal time constant spectrum and cumulative structure function are evaluated. The software was developed in Matlab environment using in-built procedures for transfer function estimation. For the validation of the proposed tool, the results are compared with ones obtained using commercially available software.
