고속용 파이프의 초음파 검사 시 캐비테이션 방지를 위한 검사장비의 개발 = Development of the Inspection Equipment to prevent Cavitation in Ultrasonic Inspection of Pipe

다국어 초록 (Multilingual Abstract)

This study developed the inspection equipment using ultrasonic in process with high speed of pipe. It was designed to prevent cavitation occurred between pipe and sensor of the equipment. Also, it was designed to maintain the balance in rotation of pipe and go on smoothly measurement of sensor. In addition, it developed module which is rotatable and can certainly achieve sealing by using mechanical seal. This developed equipment can provide good inspection performance by gaining sufficient durability in production site and increasing confidence in the measures.
