<P>PROBLEM TO BE SOLVED: To provide a method for detecting damage of pipes capable of evaluating damage in a short time at an extremely low cost compared with those of a non-destructive inspection and a hardness measurement and being effective from the view point of energy saving. <P>SOLUTION: Strain detection means 2 is stuck to a surface portion of an elbow 1 as a pipe joint of piping in which damage is predicted by a structural analysis. Conduction check means 3 is also provided that detects whether or not the elbow 1 is damaged by performing a conduction check for the strain detection means only when the inspection is required. <P>COPYRIGHT: (C)2013,JPO&INPIT |
