You can use TML Corrosion Analyses to determine corrosion rates in Risk Based Inspection (RBI). To complete the analysis, you must perform key steps in this workflow within the RBI module. If you want to specify that TML Group values should be used to calculate RBI corrosion rate values, you can perform this step using TM rather than RBI. Before you can link an RBI Component to a TML Group, you must first for the asset, and then set the Source of Calculated Corrosion Rate field for the component to Component.
To complete this task, you will need to link a TML Group to a Criticality Calculator RBI Component. When you link a Criticality Calculator RBI Component to a TML Group, RBI corrosion rate values for the RBI Analysis that you create are based on the average of the following values in the TML Corrosion Analysis:
In other words, the values in the preceding list will determine the following values in the Criticality Int. Corr. Deg. Mech. Eval record associated with the RBI Analysis that is created from the linked TML Group record:
Note: When you use TM to select a TML Group to link to a Criticality Calculator RBI Component, you will do so for only one TML Group at a time. Alternatively, via RBI, you can select more than one TML Group at a time to link to a Criticality Calculator RBI Component.
