Piping Stress Records

Records in the Piping Stress family make up the Piping Stress reference table, which GE Digital APM uses to locate the appropriate Allowable Stress value for RBI Criticality Analyses that are linked to RBI Components whose Stress Lookup Table field contains the value Piping. These values are used to calculate Pressure T-min values in RBI and Thickness Monitoring.

This topic provides an alphabetical list and description of the fields that exist in the Piping Stress family. The information in the table reflects the baseline state and behavior of these fields. The Material Type, Minimum Tensile Strength, and Minimum Tensile Yield fields exist in the Piping Stress family, but they are not used to determine the Allowable Stress value.

This family is not enabled for site filtering, which means that records in this family can be accessed by any user with the appropriate license and family privileges. See the Site Filtering section of the documentation for more information.

Field	Data Type	Description	Behavior and Usage
Allowable Stress Override	Numeric	The maximum amount of pressure that can a component can safely withstand.	This value in this field, in addition to the following other Piping Stress fields, is used to determine the value that is populated in the Allowable Stress field in the associated RBI Criticality Analysis: Code Year Construction Code Design Temperature Material Grade Material Spec Stress Lookup Table
Code Year	Character	The year in which the design code that corresponds to the component was defined.	The value in this field is used to populate the Code Year field in the associated RBI Criticality Analysis: This field must contain a value in order for GE Digital APM to retrieve: The value in the Allowable Stress field in the Piping Stress record from the Piping Stress reference table. Values in the Material Spec list in the Piping Stress record.
Design Code	Character	The design code associated with the component.	The value in this field is used to populate the Construction Code field in the associated RBI Criticality Analysis. This field must contain a value in order for GE Digital APM to retrieve the value in the Allowable Stress field in the Piping Stress record from the Piping Stress Reference table.
Material Grade	Character	The material grade of the component.	The value in this field is used to populate the Material Grade field in the associated RBI Criticality Analysis. This field must contain a value in order for GE Digital APM to retrieve the value in the Allowable Stress field in the Piping Stress record from the Piping Stress Reference table. If there is no material grade value in the specification, then this field is populated with the value NS, which implies not specified. For Construction Code B31.3 or B31.1 and Code Year 2014, if two or more Piping Stress records have the same values for Material Specification and Material Grade, then the value in this field is populated with a value in the following format: <Material Grade>-<Class>-<Size>-<Notes>
Material Specification	Character	The material specification of the component.	The value in this field is used to populate the Material Spec field in the associated RBI Criticality Analysis. This field must contain a value in order for GE Digital APM to retrieve: The value in the Allowable Stress field in the Piping Stress record from the Piping Stress reference table. Values in the Material Grade list in the Piping Stress record.
Metal Temperature	Numeric	The temperature of the metal of which the component is made.	The value in this field is used to populate the Design Temperature field in the associated RBI Criticality Analysis. This field must contain a value in order for GE Digital APM to retrieve the value in the Allowable Stress field in the Piping Stress record from the Piping Stress reference table.
