Calculating Remaining Life (Fitness-for-Service) and Reassessment Intervals

Remaining Life and Reassessment Intervals for Pressure-Cycle-Induced Fatigue Pipelines that are subjected to frequent, large pressure cycles may be at risk from failures of defects that become enlarged by pressure-cycle-induced fatigue crack growth. We can assess the potential for this phenomenon to occur in your pipeline, and we can propose an appropriate response by:

Remaining Life and Reassessment Intervals for Corrosion-Caused Metal Loss or SCC

• Comparing your actual pressure cycle spectrum to our benchmark cycles to see if it is aggressive or non-aggressive in terms of likelihood of producing fatigue crack growth
• Predicting re-assessment intervals for controlling the problem by means of periodic hydrostatic testing or periodic inspection using a “crack” tool
• Providing for the purchase of our software to make your own fatigue-life calculations and for training the use of the software.
