These are listed in the table below. Equipment outside the IMS PEI S-RBI methodology scope: | Equipment Type | Comments and References | | --- | --- | | Civil Equipment | Use IMS PEI (Civil) to apply the Civil RBI methodology. Refer to [PEI Civil](/v414/docs/pei-civil). | | Coke Drums | | | Critical Check Valves / Non-Return Valves | In IMS Critical Check Valves can be added in Piping Systems Flocs. This way the Critical Check Valve is a stand-alone Equipment, but it’s linked to the [Piping System Floc](/v414/docs/pei-piping-systems-overview), allowing the user to see if the Piping System is showing internal corrosion issues and allowing the inspector to adjust the inspection Schedule on the Critical Check Valve accordingly. | | CUI CCAM Priority 1 | See [Corrosion Under Insolation (CUI)](/v414/docs/corrosion-under-isolation-cui). | | Decoking Piping (Erosion) | | | Expansion Joints | | | Pipelines | Use [IMS PLSS](/v414/docs/plss) to assess pipelines. | | Soil-to-Air | There is no soil-to-air Component. |
