Reference Data

The Component Insulation Exclusion Data is used to completely or partially exclude the insulation of components on insulated lines with respect to interference checking.

For each piping component, piping specialty, or instrument component (excluding pipes) on an insulated line, the Piping Envelope Builder will search the Component Insulation Exclusion Data Table on the basis of the following data to determine whether or not insulation should be completely excluded from that component's interference envelope.

  • green nominal piping diameter of the component (range search)

  • red nominal piping diameter of the component (range search)

  • heat tracing requirements (range search)

  • insulation purpose (range search)

  • normal operating temperature (range search)

For piping commodities, the Piping Envelope Builder searches for the component's commodity name in the Component Insulation Exclusion Data Table using the preceding data.

  • If the piping commodity is defined in the exclusion table for those conditions, the applicable insulation thickness will not be added to the component's interference envelope.

  • If the commodity name is not specified in the exclusion table for those conditions, the Piping Envelope Builder searches for the component's model code using the same data. If a match for those conditions is found on the basis of model code, the applicable insulation thickness will not be added to the component's interference envelope.

  • Otherwise, the insulation thickness will be included in the component's interference envelope.

For piping specialties and instrument components, the Piping Envelope Builder searches for the component's model code in the Component Insulation Exclusion Data Table using the preceding data. If the component is defined in the exclusion table for those conditions, the applicable insulation thickness will not be added to the component's interference envelope. Otherwise, the insulation thickness will be included in the component's interference envelope.

The piping segment data (heat tracing requirements, insulation purpose, and normal operating temperature) are determined on the basis of the piping segment that is associated with the first connect point of the applicable component.

The Component Insulation Exclusion Data table contains 13 attributes.

  1. system_unique_no, integer

  2. commodity_name, character(6)

    This attribute identifies the commodity item name of a piping component as defined in the Piping Commodity Specification Data (Table 202 attribute 3).

    If this attribute is blank, the system will search for a match by model code.

  3. model_code, character(6)

    For piping commodities, this attribute identifies the model code as defined in the Piping Commodity Specification Data (Table 202 attribute 19).

    For piping specialties, this attribute identifies the model code as defined in the Piping Specialty Specification Data (Table 203 attribute 3).

    For instruments, this attribute identifies the model code as defined in the Instrument Component Specification Data (Table 204 attribute 3).

  4. gcp_npd_from, short

  5. gcp_npd_to, short

    These coded attributes identify the range of nominal piping diameters (lower bound to higher bound) for the green connect point of the component or instrument in NPD units.

  6. rcp_npd_from, short

  7. rcp_npd_to, short

    These coded attributes identify the range of nominal piping diameters (lower bound to higher bound) for the red connect point of the component or instrument in NPD units.

    For full size components, use a dash (-) for these attributes.

  8. heat_tracing_from, short, SN 200

  9. heat_tracing_to, short, SN 200

    These code-listed attributes identify the range of heat tracing values (lower bound to higher bound) using values from code list set 200, Heat Tracing Requirements.

    A dash (-) can be used for the from value to indicate that heat tracing requirements are not to be considered as part of the discrimination process.

  10. insul_purpose_from, short, SN 220

  11. insul_purpose_to, short, SN 220

    These code-listed attributes identify the range of insulation purpose values (lower bound to higher bound) using values from Standard Note type 220, Insulation Purpose.

    A dash (-) can be used for the from value to indicate that insulation purpose is not to be considered as part of the discrimination process.

  12. nor_oper_temp_from , double

  13. nor_oper_temp_to , double

    These attributes identify the range of temperature values (lower bound to higher bound) for the component or instrument.

    A dash (-) can be used for the from value to indicate that temperature is not to be considered as part of the discrimination process.

    The system of units for the temperature range is the same as the system of units for the maximum temperature in the Piping Commodity Specification Data Table. Note that normal design temperature, alternate operating temperature, and alternate design temperature are not considered.
