EMAT or Electromagnetic Acoustic Transducer
EMAT Inspection Tools are fully developed inside and expands inline inspection capabilities for crack detection without liquid batch. EMAT augments the UTCD inspection methods in pipelines and will add value to the integrity assessment of gas pipelines.
Accurate inspection and diagnosis of cracks
EMAT or Electromagnetic Acoustic Transducer inspection method is effectively creating and using ultrasound for the detection of cracks-stress corrosion cracking without the need for a liquid batch. A secondary advantage of the EMAT technology is that it may detect disbanded coating.
The EMAT technology based on the generation of ultrasonic waves is expanding ultrasonic inspection methods from only liquid lines to gas pipelines. It has distinct benefits that make it the technique of choice for many applications with accurate 360-degree inspection and 100%-line coverage.
