A Microwave-Based Non-Destructive Testing Method for the Long Range Inspection of Metallic Pipe
update：2020-06-16
Features
We are developing a non-destructive testing method for the long range rapid inspection of metallic pipe using microwaves. The method propagates a microwave inside a pipe, and evaluates flaws appearing at the inner surface of the pipe on the basis of the reflection and transmission of the microwave. The method does not require scanning probes unlike conventional non-destructive methods, which enables one to inspect a pipe quite quickly. Our experimental validations have demonstrated the effectiveness of the method using a pipe as long as 30 m.Targeted Application(s)/Industry
The NDT method proposed here is applicable when many pipes are inspected or conventional methods are not available due to pipe length and its configuration.Researchers
