High-Temperature Hydrogen Attack (HTHA): Recognize & Protect Your Equipment from HTHA Damage

When equipment is exposed to high-temperature hydrogen without  adequate design and material selection, the impact can be catastrophic. Changing temperatures cause the interactions between the mechanical, metallurgy, and environment to shift and result in several high-temperature damage mechanisms, including High-Temperature Hydrogen Attack (HTHA). To prevent both unanticipated damage and failure of equipment, you need to accurately identify HTHA-susceptible locations, predict current damage, inspect for HTHA, and assess the remaining life. Involving E²G while evaluating equipment in HTHA service will reduce failure risk, help prevent unnecessary repairs or replacements, and extend equipment life and availability.
