Historical management strategies for equipment subject to high temperature hydrogen attack (HTHA) have traditionally relied on risk assessment with empirical or quantitative models. Given a lack of confidence in early inspection techniques for HTHA, operation of equipment with known susceptibility to HTHA for prolonged service periods has been limited. A quantitative model for HTHA damage has been created based on void growth models combined with a creep model. This model has been calibrated to known failures and damage cases reported in industry (API 941). The results are time-based Nelson curves and the ability to combine varying operating conditions to calculate a life and combining this with practical adjustment factors and NDE results allows for more accurate life estimates and accumulated damage predictions. The theory and practical examples will be included.
