About Corrosion Analyses that Include TML Groups

You should include TML Groups in your Corrosion Analyses if any of the assets that you will analyze in TM consist of components that you want to analyze individually, or you want to analyze corrosion data for certain groups of TMLs on an asset or component. What the TML Groups that you create represent will depend upon whether the associated Equipment record represents a standalone asset or an asset that contains components.

If you use this method:

You must configure preferences for the Equipment family.
Each TML Group that you create will be linked to an Equipment record representing the asset through the Has TML Group relationship.
An Asset Corrosion Analysis and Corrosion Analysis Settings will be created and linked to the Equipment record representing the asset, as well as each TML Group that is linked to that asset.
All TMLs that you create will be linked directly to a TML Group. In this case, TMLs should not be linked directly to the asset.

Details

The following diagram illustrates the structure of Corrosion Analyses that include TML Groups. Specifically, this diagram illustrates the records and links that would exist if a Corrosion Analysis included one Equipment record (representing an asset), which is linked to three TML Groups. The boxes in the diagram are labeled according to the records that they represent, and the lines connecting the boxes represent the links between these records in a Corrosion Analysis.

The following table provides information on how the records that are illustrated in the diagram are created manually or automatically.

Record	Notes
Corrosion Analysis Settings	Manually for Equipment records -and- Automatically for TML Groups that you create and link to those equipment records.
Asset Corrosion Analysis	Automatically for Equipment records and TML Groups, but at different points in the workflow.
Equipment	Manually.
Thickness Measurement	Manually.
Thickness Measurement Location	Manually.
Thickness Monitoring Task	Automatically (when a Corrosion Analysis Setting are created).
TML Corrosion Analysis	Automatically (when a Thickness Measurement Location record is saved).
