A Study on the Development of Ultrasonic Scanning Device for the Inspection and Evaluation of Creep Damage of HK - 40 Reformer Tube Welded Zone

HK-40 고온반응관 용접부의 Creep손상 진단기법 및 자동 초음파탐상장치의 개발에 관한 연구

Detection of creep damages in centrifugally cast HK-40 reformer furnace catalyst tube is a common problem for the safety and scheduled operation of chemical plants. This study was focused on the development of an automatic ultrasonic scanning device with which the creep damage of welded zone of HK-40 reformer tubes is detected and evaluated.
