Radiographic Examination of Corrosion and Deposits Using X and y Radiation Source

Bruno Breka ; TPK-Zavod d.d., Zagreb, Hrvatska

Abstract

The reliability and the safety of equipment in industrial plants are influenced by material degradation processes, such as corrosion, erosion, cavitation, deposits and blocking of pipes. These processes might reduce production, cause leaks, fires or unpredictable and costly shutdowns due to the repair and replacement of critical components. The condition of critical components in industral plants can be monitored by the proper use of the NDT inspection methods even while the plant is in operation. A major inspection challange is monitoring and the examination of insulated pipes. The common methods for detecting corrosion and deposits in insulated pipings involve double wall and tangential radiographic inspection. This paper reviews fundamental techniques and test arrangements of corrosion and deposit radiographic inspection using X and γ radiation sources, whose use depends on demands and is in accordance with HRN EN 16407-1 and 16407-2 standards.
