Thermographic detection of abraded pipeline walls in the industrial installations

Abstract

The aim of this paper is to develop a new method for detection of abraded walls in the industrial pipelines. The reason of the reduction of pipelines wall thickness is mainly long time exploitation. Also high temperature and variable pressure of the transported medium cause of faster walls abrasion process in the pipelines. Too long exploitation can lead to break a pipeline's wall, and in the case of a dangerous gas it may lead to an explosion. The presented results show the dependence between surface temperature and a wall thickness of the pipeline.
