Systematized piping loops or circuits are systems used in Risk Based Inspection analysis to assess the likelihood and consequence of failure.
Other systematization may also prove useful, such as, i.e. inspection, consequence, materials of construction and chemistry.
Each loop or circuit maybe identified using a unique code, with description about; process, material & degradation mode, material, cladding, C.A, specs.
See also systems theory: Note the exact definition of the systematized risk analysis " loop" is left to the reader and their requirements of the system analysis required, however to ensure consistency and that the expected results is produced, this should be defined before they are constructed.
It is suggested that a “true” corrosion loop should be a grouping were the degradation mechanism is "likely" to be the same i.e. By defining the barrier limits of Damage Susceptible Areas, the susceptibility of any part is similar to that of the whole.
