Content overview: “Steel Absorbs Gas Like a Sponge: The Hidden Danger of HTHA”. High Temperature Hydrogen Attack (HTHA) is a silent threat in industrial settings, where steel absorbs hydrogen gas at high temperatures, forming methane bubbles that weaken the metal. This phenomenon can lead to catastrophic failures in equipment like pressure vessels and pipelines, especially in the fertilizer and petrochemical industries. In this video, we demonstrate how ultrasonic testing (NDT) can detect HTHA damage before it becomes critical. Using advanced scanning techniques, we reveal the internal bubbles that compromise steel integrity.
The process is akin to seeing a sponge inside solid metal. We explain the chemistry behind HTHA, where hydrogen reacts with carbon in steel to form methane, creating internal pressure that causes cracks. Prevention involves using hydrogen-resistant alloys and monitoring operating conditions. This video is essential for engineers and safety professionals, offering a clear visual understanding of a hidden industrial hazard.
