Nominal T-Min is a value that represents the minimum thickness of a pipe based upon accepted industry standards. The Nominal T-Min value takes into account various design specifications and determines the minimum thickness associated with that criteria. The Nominal T-Min value is retrieved using values from Thickness Measurement Location records and records in the Piping Nominal T-Min reference table. Using the Nominal T-Min Preferences section, you can configure which fields you want to use for retrieving the Nominal T-Min value for Thickness Measurement Location records that are linked to Equipment or TML Group records that represent pipes, or records that store equipment or component data for pipes.
In the Nominal T-Min Preferences section, under the Fields for Nominal T-Min Lookup heading is a list of all these fields that exist in the Piping Nominal T-Min family.
Each field in the Piping Nominal T-Min family corresponds to a field in the Thickness Measurement Location family. By selecting a field in the Fields for Nominal T-Min Lookup list, you are indicating that you want to use that field for looking up Nominal T-Min values. This means that values in the associated fields in Thickness Measurement Location records will be compared to values in the Piping Nominal T-Min reference table and that a Nominal T-Min value will be returned only if a match is found. Any field that is not selected in the Fields for Nominal T-Min Lookup list will not be used for looking up the Nominal T-Min value. In other words, values in those fields of Thickness Measurement Location records are not required to match values in corresponding field in the Piping Nominal T-Min reference table.
Note: If no fields are selected in the Fields for Nominal T-Min Lookup list, the Nominal T-Min Lookup feature will be disabled. In other words, a Nominal T-Min value will never be retrieved automatically for any Thickness Measurement Location record.
