NDT Method
NDT vs Destructive Testing
Understand the difference between non-destructive and destructive testing, and when each is appropriate.
Overview
Destructive testing evaluates material properties by loading a sample to failure — useful for verifying strength but consuming the sample. Non-destructive testing evaluates integrity without damaging the component, so it can be used on the actual in-service asset.
Most integrity and compliance work uses NDT because it inspects the real equipment without taking it out of service.
Key Differences
- Destructive testing consumes the sample
- NDT leaves the asset usable
- Destructive testing verifies strength properties
- NDT verifies in-service integrity
