| Time of Flight Diffraction

Time of Flight Diffraction: Plant equipment in the process, power and refining industries undergo exposure to conditions that may result in degradation, corrosion, or failure. In today’s competitive climate, the operators of these plants come under increasing pressure to improve equipment reliability, while reducing overall costs.

TOFD differs from conventional pulse echo ultrasonics in that it depends on diffracted energy rather than reflected energy, monitored in the form of signal height or amplitude.

Spectra Asset Integrity Management utilise TOFD in conjunction with other non-destructive testing methods such as phased array. Our inspectors are PCN Level 2 qualified and are highly experienced in using this testing method. Their expertise can help you to ensure that your welded structures or items are compliant with industry codes, standards or customer specifications.

Spectra Asset Integrity Management offers a comprehensive range of non-destructive testing methods. Therefore we can provide the other methods used to complement time of flight diffraction such as phased array.
