Non-destructive Examination, also known as non-destructive testing, includes methods to test or evaluate the structural condition or defects of a container without damaging it. Worldwide inspection services companies make use of several NDE methods to analyze welding defects or other structural or system damage caused to tanks, containers, or water towers.
Here, we have listed some of the widely used methods to conduct Non-destructive Examination.
- Acoustic Emission Testing (AE)
Acoustic Emission Testing is a passive testing technique. In this method, the API inspection companies look for short bursts of ultrasound that are emitted by cracks under the loads. The sensors are disseminated over the surface of the containers to check for acoustic emission. In highly stressed areas, one can detect AE from plasticization. The AE testing is used while conducting proof tests of a pressure vessel or structural health monitoring for bridges.
- Electromagnetic Testing (ET)
As the name suggests, in Electromagnetic testing, an electric current is passed through a conductor. The ET consists of three types; they are, eddy current testing, remote field testing, and alternating current field measurement.
- Ground Penetrating Radar (GPR)
Ground Penetration Radar is a geophysical method of NDE. In this testing technique, radar pulses are sent …
