摘要： PROBLEM TO BE SOLVED: To provide a bent pipe stress evaluation method and a bent pipe stress evaluation device capable of evaluating axial and circumferential stress generated in the bent pipe precisely from the amount of sectional flatness in a straight pipe connected to the bent pipe even if it is not possible to directly measure the bent pipe section since other buried objects, or the like approach. SOLUTION: A control section 7 sets appropriate amount-of-flatness measurement section 41 according to pipelines to an exposed straight pipe 35a, based on previously input pipeline information. The amount-of-flatness measurement section 41 is set at a position separated by measurement distance 47 that is 0.5 to 1.5 times larger than a pipe diameter 45 in the direction of the straight pipe 35a from a pipe connection section 43, namely a connection section of a bent pipe 37 and the straight pipe 35a. Then, the amount of flatness in the straight pipe is calculated from the amount of flatness in the straight pipe 35a at the amount-of-flatness measurement section 41. Then, the amount of flatness in the bent pipe is calculated from a flatness ratio at the position of the amount-of-flatness measurement section 41 and the measured amount of flatness in the straight pipe, thus calculating axial and circumferential stress generated in the bent pipe.

摘要： PROBLEM TO BE SOLVED: To provide a stress evaluating method and a stress evaluating device for evaluating a curved pipe for simply and precisely calculating the stress generated in the curved pipe constituting a pipe line.
SOLUTION: Regarding the curved pipe A to be evaluated, if a measuring limit is exceeded, the stress evaluation is performed as follows: a distribution of the stress in a curved pipe B being adjacent to the pipe A is measured by a magnetic anisotropy sensor, flatness value of the curved pipe B is obtained from the relational formula of the stress-moment relation and the moment-flatness value, and an initial diameter of the pipe B is obtained from a measure of the diameter of the pipe B. The flatness vale of the pipe A is obtained from the measurement of the diameter of the pipe A considering that the initial value of diameter of the pipe B is equivalent to that of the pipe A, and the distribution of the stress in the curved pipe A is calculated using the relational formula of moment-flatness value and the relational formula of stress-moment. Wherein, the relational formula of moment-flatness value is derived e.g. by developing the theoretical formula of Rodabaugh & George etc., regarding displacement in a sectional direction of the curved pipe.
