High-temperature steel assets in refining, manufacturing, and petrochemical plant assets can be affected by High Temperature Hydrogen Attack (HTHA) degradation. MISTRAS’ proceduralized HTHA programs combine reviews of operating conditions for HTHA susceptibility, and non-destructive testing (NDT) inspections to help enable immediate remedial action when HTHA is found.
