Reference Data

This command creates a report assessing the impact of multiple changes in the unapproved RDB. Selecting this command from the Reference Data Revision Manager form activates the Proposed RDB Changes Report form.

You must make changes to the unapproved Material Reference Database in order to assess the effect of these changes. You are responsible for restoring the unapproved Material Reference Database to its original state if you decide not to pursue these changes.

Refer to the section titled Summary of Report Parameters and Discrepancy Hierarchy found at the beginning of this chapter for information on the order of significance of reported problems.

Piping Commodities

The system extracts the following data from the model for the purpose of reading piping commodity specification data from the Material Reference Database. This is the same data that is used for the placement or reconstruction of a piping commodity.

piping materials class

second size

commodity name

option code

first size

maximum temperature

The first size and second size are determined from the piping segment data and not from the component itself.

If the piping commodity in the model is a branch that was initially placed using a branch table from the Reference Database, the system reads the appropriate branch table from the Piping Materials Class data to determine if there has been a change in the commodity name for the branch. If so, this component is flagged as requiring reconstruction.

The system compares the following data for consistency between the model and the Reference Database for piping commodities. The data which may impact the geometry and/or the symbology in the model is designated by an asterisk.

* end preparation - green

* commodity code

* pressure rating - green

* model code

* schedule/thickness - green

* modifier

* table suffix - green

* geometric industry standard

* end preparation - red

weight code

* pressure rating - red

fabrication category

* schedule/thickness - red

materials grade

* table suffix - red

Note that user overrides of fabrication category and schedule/thickness will not be included in the report.

The system compares the gasket thickness for each bolted end of a piping commodity with the gasket separation in the corresponding Piping Materials Class data. If a value is defined in the Reference Database, the gasket thickness at the bolted end is compared with that value. If a Gasket Separation Table name is defined, that table is used to determine a gasket separation value for comparison with the gasket thickness at the bolted end.

The system compares the specification data for any connect point of a piping commodity which has been designated as a tap with the appropriate data (either the specification data from the Tap Properties Data in the Reference Database or from another connect point.

The system compares the NPD at each connect point of the component with the NPD of the segment.

The system compares the schedule thickness data for a component in the model to the corresponding data in the Material Reference Database. The comparison will consider the following issues at a minimum:

  • the application of the schedule/override in the model.

  • changes to the value for the schedule thickness in the Piping Commodity Data within the Material Reference Database.

  • changes to the joint efficiency value in the Piping Commodity Data within the Material Reference Database.

  • changes to the value for the thickness equation in the Piping Materials Class Data within the Material Reference Database.

  • changes to the Thickness Data Table or the Materials Data Table.

Refer to the section titled Summary of Report Parameters and Discrepancy Hierarchy found at the beginning of this chapter for information on the order of significance of reported problems.

Piping Specialties and Instruments

The system extracts the component number from the model for the purpose of reading piping specialty and instrument specification data from the Material Reference Database. The component number is also used for the placement or reconstruction of a piping specialty or an instrument. For example, instrument_comp_no is used for instruments, and piping_comp_no is used for piping specialties.

The system compares the following data for consistency between the model and the Reference Database for piping specialties and instruments. The data which may impact the geometry and/or the symbology in the model is designated by an asterisk.

* end preparation - green

* physical data id

* pressure rating - green

* model code

* schedule/thickness - green

* modifier

* table suffix - green

* geometric industry standard

* end preparation - red

weight code

* pressure rating - red

fabrication category

* schedule/thickness - red

materials grade

* table suffix - red

The system compares the gasket thickness for each bolted end of a piping specialty or instrument with the gasket separation in the corresponding Piping Materials Class data. If a value is defined in the Reference Database, the gasket thickness at the bolted end is compared with that value. If a Gasket Separation Table name is defined, that table is used to determine a gasket separation value for comparison with the gasket thickness at the bolted end.

The system compares the specification data for any connect point of a piping specialty or instrument which has been designated as a tap with the appropriate data, i.e. either the specification data from the Tap Properties Data in the Reference Database or from another connect point. Piping specialties and instruments are excluded from this report when the specification data and the geometry data is defined by the user (not defined in the Reference Database).

The system compares the green specification data in the Reference Database with all connect points for that component in the model which are designated as having green connect point properties.

The system compares the red specification data in the Reference Database with all connect points, if any, which are designated as having red connect point properties.

The system compares the schedule thickness data for a component in the model to the corresponding data in the Material Reference Database. The comparison will consider the following issues at a minimum:

  • the application of the schedule/override in the model.

  • changes to the value for the schedule thickness in the Piping Commodity Data within the Material Reference Database.

  • changes to the joint efficiency value in the Piping Commodity Data within the Material Reference Database.

  • changes to the value for the thickness equation in the Piping Materials Class Data within the Material Reference Database.

  • changes to the Thickness Data Table or the Materials Data Table.

Operating Sequence

  1. Select the Proposed RDB Changes Report option.

    The system activates the Proposed RDB Changes form.

  2. Select the extent of the project to be processed.

    • Project — process all piping models for the entire project.

    • Piping Design Area — process the selected piping design areas.

    • Models — process the selected models within a selected design area.

  3. You can key in changes to the Report Node, Report Path, and Report Name for the summary report output or use the default location and name.

    The default location for the summary report is determined by the Report Management Data of the Report Manager.

  4. Select the desired output method for the summary report: Print/Delete, Print/Save, or Save. If you will be printing the summary report, select a queue from the pick list.

  5. Accept to Submit Job, Restart or Exit

    Set the toggle to Submit Immediately or select Delayed Submit and fill in the day and time to process the request.

  6. Select Accept to submit the request for processing.

    The system submits the request to the batch queue PDreport. It updates the batch log file periodically to include a list of piping models which have been processed. The proposed RDB changes report file has an extension of .pcs and is created in the model directory as <model_number>.pcs. If the summary report is printed as a result of creating this report, this report will also be printed.
