| Outline of Final Research Achievements |
For effective maintenance and management of an agricultural pipeline system, it is necessary to evaluate not only the damage of pipe materials but also the detection of risk. In this research, development of damage evaluation method are proposed by applying NDT methods. Thus, material damages were detected in service pipeline system, based on NDT surveying and risk analysis. The risk indexes were dependent on the degree of material damage and could be evaluated applying NDT parameters. By evaluating the risk in service pipeline based on these results, estimation of safety status was successfully detected by non-destructive inspection methods.
