Anchor bolt Inspection Phased Array Thinning Ultrasonic Test
Anchor bolts have been used to fix components in nuclear power plant to concrete structure. Bolt thinning is supposed to occur under long term operation of nuclear power plant in corrosive environments and requires a development of nondestructive inspection method. We have begun some internal researches since 2009 and developed a unique PA-UT method using delayed echoes. Additional works were conducted recently to show its performance such as a detectable maximum defect length and depth, which are rep...

Inaccessible component piping Reinforcement plate Ultrasonic Testing Wall thickness
To confirm soundness of the piping, the measurement using ultrasonic thickness meters is performed generally. Ho wever, this method cannot apply to pipes which are inaccessible by component such as supports or reinforcement p lates, because the method uses normal beam technique.This paper describes the medium range transmission techniqu es using angle beam probes which provide potential for measurement of wall thickness of inaccessible components....
