A defined section of piping grouped for inspection, integrity assessment and maintenance based on common operating conditions and degradation mechanisms.
A Piping Circuit is a defined section of piping that shares similar process conditions, materials, operating parameters and expected degradation mechanisms. Piping circuits are established to support inspection planning, risk assessments and integrity management by grouping piping that is expected to exhibit similar corrosion and damage behavior.
Piping Circuits provide the basis for inspection planning and integrity assessment of piping systems.
Piping circuits are widely used within API 570 and Risk-Based Inspection (RBI) programs to define inspection boundaries and evaluate corrosion rates, remaining life and fitness for continued service.
A Piping Circuit groups piping for inspection and integrity management, whereas a P&ID represents the engineering design and connectivity of the complete process system.
