Latest in Pressure Cycle Induced Fatigue Crack Growth Modeling

Recent high-profile pipeline incidents have increased awareness of integrity threats associated with legacy seam-welded pipe. Additionally, expectations from the public, regulators and pipeline operators to effectively manage these threats have increased. Pipeline operators use guidance published in PHMSA’s TT05 – Low Frequency ERW and Lap Welded Longitudinal Seam Evaluation– to model the effect of pressure cycle-induced fatigue on the growth of crack flaws to determine the optimum integrity re-assessment date prior to their growth to a critical level. Operators typically considered a short window of pressure cycling data to represent the historical operations of a pipe
