| Abstract |
| Nondestructive diagnostic technology can be used to check for abnormalities such as metal loss, deformation, and cracks in water pipelines. However, new standards and guidelines for water pipeline maintenance must be revised or established in order to apply new technologies such as nondestructive diagnosis to the field. Herein, policies and guidelines are proposed for the diagnosis of water pipelines using nondestructive technology. Amendments are proposed to allow accurate and reliable nondestructive diagnostic technology to be applied to pipeline maintenance by reviewing the diagnostic standards and laws for water pipelines. The design standards for water conveyance, water transmission, and water distribution pipelines have been revised in order to use advanced technologies such as nondestructive technology to identify abnormalities while minimizing the impact on facilities when inspecting and diagnosing water pipelines. In addition, a revision of the detailed guidelines of the Ministry of Land, Infrastructure, and Transport according to the KS and ASTM standard is required to allow for the use of nondestructive equipment when inspecting welds. Nondestructive diagnostic guidelines that summarize the characteristics and performance of nondestructive diagnostic equipment, diagnostic procedures, and verification processes are also proposed to help managers understand the technology and easily apply it in the field when diagnosing water pipelines. |
