High temperature hydrogen attack

WebJan 1, 2012 · HTHA (sometimes called ‘methane reaction’) occurs at high temperatures between the gaseous molecular hydrogen contained inside the pressure vessel and the carbon atoms located in the steel matrix or in carbides. Methane molecules are produced during this reaction. WebInspection Challenges In the Oil and Gas industry, High Temperature Hydrogen Attack (HTHA) can occur in steel operating at high temperature, usually above 205°C (400°F). It is the result of hydrogen disassociating and dissolving in the steel, eventually leading to fissures as well as cracking.
