Htha damage mechanism
Webfatal explosion and fire was caused by a damage mechanism known as high temperature hydrogen attack, or HTHA, which severely cracked and weakened the carbon steel heat exchanger over time, leading to a rupture.1 Industry uses a standard for determining vulnerability of equipment to HTHA, known as American Petroleum WebOct 21, 2024 · Volumetric-like flow damage (fissuring rupture) along the 2-in. tube base metal. This damage is likely attributed to HTHA, which is a time-temperature-pressure function. This damage mechanism results in degradation of material properties at elevated temperature s, leading to sudden and catastrophic failure.
