    • The present invention relates to a device for measuring the properties of facility materials exposed in an hyperbaric environment. The device for measuring material properties in a hyperbaric environment accurately grasps the property variation of materials for a facility exposed in a hyperbaric environment by obtaining measured data on ultrasonic waves and resistivity of a sample using a first measuring member including an ultrasonic wave sensor and a resistivity sensing part, and calculating the results obtained by measuring the properties of the sample by accurately analyzing the measured data of the sample using a second measuring member. Accordingly, the present invention can accurately measure the properties of materials of an industrial facility even if an error or failure is generated in any one characteristic among the characteristics of the ultrasonic waves and the resistivity used during a step for measuring the properties of the materials for a high pressure facility.

    • A high-pressure tank damage detecting method for detecting a sign of breakage of a high-pressure tank containing a high-pressure fluid in a nondestructive way at an early stage, and an apparatus for the method are provided. By means of an acoustic emission sensor (AE sensor) (1), a sign of breakage caused when a high-pressure tank (2) is filled with a fluid is detected in a nondestructive away. One AE signal detected by the AE sensor (1) is counted as one hit. The hit rate representing a variation with time of the hits is determined, and a sign of breakage is detected from the variation of the hit rate. When a micro-crack in the high-pressure tank (2) progresses or when micro-cracks join and form one macro-crack, the hit rate of the AE signal does not increase with an increase of the internal pressure of the high-pressure tank (2) and comes into a saturated state. The saturated state of the hit rate is judged as a sign of breakage.
