DEVICE AND METHOD FOR MEASURING BEARING CAPACITY OF HEAT EXCHANGER PIPE

PROBLEM TO BE SOLVED: To provide a device and a method for measuring the bearing capacity of a heat exchanger pipe which are capable of measuring contact force between the heat exchanger pipe and a swing preventive member with high precision.SOLUTION: The measuring device includes: a cable 101 which is flexible and can be inserted into the inside from an edge of a heat exchanger pipe 66; a moving body 102 at the tip of the cable 101 which is connected to the inside of the heat exchanger pipe 66 with a prescribed gap; a probe 103 which is disposed on a periphery of the moving body 102 and transmits/receives an ultrasonic wave to/from the inside of the heat exchanger pipe 66; and a control apparatus 104 for obtaining the bearing capacity of the heat exchanger pipe 66 by a swing preventive metal fitting 69 on the basis of a measurement signal from the probe 103.
