Tank T-Min Annular Ring Reference Table

Records in the Tank T-Min Annular Ring family make up the Tank T-Min Annular Ring reference table, which GE Digital APM uses to locate the appropriate Calculated T-Min value for each Thickness Measurement Location (TML) with the value API 653 in the Design Code field and Annular Ring in the Tank Type field.

The baseline GE Digital APM product does not include any records in the Tank T-Min Annular Ring family. For Calculated T-Min values to be determined, you must create Tank T-Min Annular Ring records using values from industry standards.

Details

The following table lists the default fields in the Tank T-Min Annular Ring family and the corresponding fields in the Thickness Measurement Location family.

Tank T-Min Annular Ring Field	Corresponding TML Field	Notes
Hydrostatic Test Stress Lower Bound	Allowable Stress	The Hydrostatic Test Stress Lower Bound field establishes the lower boundary of a stress range. An Allowable Stress value from a TML that falls within the established range is considered a match.
Hydrostatic Test Stress Upper Bound	Allowable Stress	The Hydrostatic Test Stress Upper Bound field establishes the upper boundary of a stress range. An Allowable Stress value from a TML that falls within the established range is considered a match.
Plate Thickness Lower Bound	Plate Thickness	The Plate Thickness Lower Bound field establishes the lower boundary of a plate thickness range. A Plate Thickness value from a TML that falls within the established range is considered a match.
Plate Thickness Upper Bound	Plate Thickness	The Plate Thickness Upper Bound field establishes the upper boundary of a plate thickness range. A Plate Thickness value from a TML that falls within the established range is considered a match.
T-Min	Minimum Thickness	The T-Min value that corresponds to the stress range and plate thickness range identified by the Allowable Stress and Plate Thickness values in the TML becomes the Calculated T-Min value for that record. This value can be used to populate the Minimum Thickness field in the TML, or a user-defined value can be specified instead.
