Thickness Monitoring Rules Lookup

Thickness Monitoring includes a set of baseline Thickness Monitoring Rules Lookup records and the associated Rules Library projects. You can use the baseline records as they are delivered, or you can modify them to suit your specific needs. Like all reference table records, Thickness Monitoring Rules Lookup records are best viewed through a query. You can manage Thickness Monitoring Rules Lookup records via .

Thickness Monitoring Rules

The following table provides a list of the fields that exist in the Thickness Monitoring Rules Lookup family, descriptions of these fields, and information about any corresponding Thickness Measurement Location (TML) fields.

Field Name	Field Description	Corresponding TML Field
Asset Type	Contains a value that identifies the type of equipment to which a TML is linked. The value in this field determines which values are available in the Design Code field. For example, when Piping is selected in the Asset Type field, only piping design codes will appear in the Design Code field.	This field exists simply to facilitate the creation of new Thickness Monitoring Rules Lookup records by filtering values in the Design Code field.
Code Year	Contains a list of years associated with the selected Design Code.	Code Year (T-Min Formula)
Design Code	Contains a list of design codes that are appropriate for the equipment type selected in the Asset Type field.	Design Code
Component Type	Contains a list of component types.	Determined by the equipment type, which is derived from the value in the Design Type field, and can be any of the following fields: Vessel Type for Pressure Vessel TMLs. Tank Type for Tank TMLs. No Mapping for Piping TMLs.
Formula Classification	Contains a list of formula classifications.	Determined by the equipment type, which is derived from the value in the Design Type field, and can be any of the following fields: Piping Formula for Piping TMLs. PV Formula for Pressure Vessel TMLs. No Mapping for Tank TMLs.
T-Min Formula Rule	Contains a reference to a project in the Rules Library.	This value is derived for each TML based on values in other fields. Although the derived value is not stored in the TML itself, it identifies the formula that will be used to determine the Calculated T-Min value for a TML.
MAWP Formula Rule	Contains a reference to a project in the Rules Library.	This value is derived for each TML based upon values in other fields. Although the derived value is not stored in the TML itself, it is used to determine the Maximum Allowable Working Pressure value for a TML.
