The systematic measurement, analysis and trending of wall thickness to assess asset degradation and remaining life.
Thickness Monitoring is the systematic process of collecting, analysing and trending wall thickness measurements to evaluate corrosion, erosion and other degradation mechanisms affecting the integrity of equipment and piping. Thickness Monitoring supports inspection planning, Remaining Life assessments, Fitness-for-Service evaluations and Risk-Based Inspection programs by providing objective evidence of material loss over time.
Thickness Monitoring evaluates wall loss trends to support asset integrity management and inspection planning.
Thickness Monitoring programs use measurements obtained at designated Thickness Measurement Locations to identify degradation trends, calculate corrosion rates and support engineering decisions relating to continued service, repair or replacement.
Thickness Monitoring is the ongoing integrity management process, whereas a Thickness Measurement Location is the individual location where thickness measurements are obtained.
