Electromagnetic Acoustic Transducer (EMAT): Pipeline Inspection

Electromagnetic Acoustic Transducer (EMAT) is a non-destructive testing technology that has applications in a wide range of industrial sectors.


Our EMAT inspection method is effectively creating and using ultrasound for the detection of cracks/stress corrosion cracking without the need for a liquid couplant. A secondary benefit of the EMAT technology is that it may detect disbanded coating.

This technology based on the generation of ultrasonic waves is expanding ultrasonic inspection methods from only liquid lines to gas pipelines. It has distinct advantages that make it the technique of choice for many applications with accurate 360-degree inspection and 100% line coverage.
