[Application Note] Latest Inspection Method for Early Detection of High-Temperature Hydrogen Attack (HTHA), PCI Coherence Imaging [PDF Download Available]

Eddyfi Technologies Eddyfi Technologies ジャパンオフィス
In aging infrastructures such as the petrochemical industry, potential vulnerabilities that plant engineers and maintenance teams should be aware of, particularly high-temperature hydrogen attack (HTHA), are cited as one of the dangerous defects. This defect occurs when hydrogen contained in low-alloy steel changes its atomic form at high temperatures, permeating the steel and forming methane. Once methane is trapped within the metal, tiny bubbles form, ultimately leading to cracking and fissures. Eddyfi proposes advanced, portable ultrasonic inspection tools for the early detection of HTHA, utilizing TOFD, phased array ultrasonic testing (PAUT), and the latest total focusing method (TFM). This technology enables early detection of HTHA, enhancing the safety of critical equipment. For more detailed information, please [contact us].

高温水素アタック1.png

Inspection method for detecting high-temperature hydrogen attack (HTHA) before rupture occurs.

We propose an advanced portable tool capable of performing all ultrasonic techniques necessary for the identification of high-temperature hydrogen corrosion!

Regarding the aging of infrastructure in the petrochemical and other industrial sectors, there are various potential vulnerabilities that plant engineers and maintenance departments must pay attention to. Repeated loads and fatigue stress can lead to cracking over time, but there is another type of defect that is equally dangerous. This particular issue is difficult to detect and, if left unaddressed, can pose a serious threat to the integrity of the equipment. Therefore, managers responsible for maintaining industrial infrastructure must always remain vigilant and pay close attention to the latest best practices and technologies to identify and address potential issues. *For more detailed information, please refer to the PDF document. Feel free to contact us for further inquiries.*
