These are only important points or a summary of points for the process piping in-service inspection and should not be assumed as the entire piping inspection procedure. A piping inspection procedure is a comprehensive document, which need to cover inspection methods to be employed, equipment and material to be used, qualification of inspection personnel involved and the sequence of the inspection activities at the minimum. Creating a piping inventory list indicating the line number, pipe specification class, rating, schedule, pipe origin location (from) and pipe destination location (to) Creating piping isometric sketches to facilitate inspection and the recording of corrosion monitoring locations (CMLs)Dividing whole unit piping into piping circuits based on process condition and potential degradation mechanism Selecting appropriate NDE techniques for each piping circuit based on the circuit damage mechanism. Determination of CMLs points in piping isometric sketches based on the potential for general or localized corrosion and service specific damage mechanisms Determination of piping service class based consequence of failure and instruction stated in API 570 or based on the Risk Based Inspection method.
