Copper is generally known as a metal which is excellent in workability and resistant to corrosion. Copper tube is used in a wide range of heat transfer field. However, when ant nest corrosion occurs on copper tube, the progression rate of corrosion is enough fast to penetrate the tube prematurely. In recent years, phosphorus added to the copper has been found to have an influence on progression of ant nest corrosion. Test of ant nest corrosion on different low phosphorus content in the copper clarified the influence of low phosphorus content in copper for ant nest corrosion. [ABSTRACT FROM AUTHOR]

In air conditioning and refrigeration, ant's nest corrosion is known as a problem caused by low carboxylic acid in the environments. In this study, CT scanner technology is recommended for observing corrosion, especially ant's nest corrosion, from the viewpoint of accurate developed material estimation The problem of conventional cross-sectional observation technologies and evaluation of its results is discussed.
