PRD Components

About Pressure Relief Devices (PRD)

A pressure relief device (PRD) is a device that protects equipment or RBI Components from pressure buildup. In RBI, you will store information about PRDs in records belonging to subfamilies of the PRD Components family.

Specifically, RBI supports the use of the following types of PRDs:

  • Pressure relief valves (stored in Criticality Calculator PRD Component - Relief Valve records)
  • Rupture disks (stored in Criticality Calculator PRD Component - Rupture Disk records)
Note: Throughout this documentation, where the distinction between the two subfamilies is irrelevant to the discussion, you will see the term PRD Components to refer to a record in either subfamily.

About Identifying Protected Equipment or RBI Components

After you have created a PRD Component to identify a pressure relief device (PRD), you can identify the equipment or RBI Components that the PRD protects.

  • A PRD can protect either equipment or RBI Components, but not both.

    • If a PRD protects equipment, it can protect one or many pieces of equipment.
    • If a PRD protects RBI Components, it can protect one or many RBI Components.
  • A single piece of equipment can be protected by multiple PRDs.
  • A single RBI Component can be protected by multiple PRDs.
  • If you identify a new protected equipment or RBI Component for a PRD for which an RBI PRD Analysis already exists, the existing RBI PRD Analysis will become invalid. You will need to create a new RBI PRD Analysis to account for the new protected equipment or RBI Component.

Access a PRD Component

About This Task

Important: To distinguish PRD Components from RBI Components in a Corrosion Loop, PRD Components have the icon before the Component ID. All PRD Components function the same way as RBI Components.

Procedure

  1. Access the Asset Summary workspace for the asset that contains the PRD Component that you want to access.

    -or-

    Access the Corrosion Loop that contains the PRD Component that you want to access.

  2. Below the graph, select the link corresponding to the component that you want to access.

    -or-

    In the left pane, select the component that you want to access.

    The workspace for the selected component appears, displaying the Component Overview section.



  3. Select the Component Details tab.

    The Component Details section appears, displaying the datasheet of the Component.



    Note: If needed, modify values in the available fields, and then select to save your changes.

Create a PRD Component

About This Task

This topic describes how to create a new PRD Component and link it to an Asset or a Corrosion Loop. You can also link an existing PRD Component to an Asset or a Corrosion Loop.

Important: To distinguish PRD Components from RBI Components in a Corrosion Loop, PRD Components have the icon before the Component ID. All PRD Components function the same way as RBI Components.

Procedure

  1. Access the Asset Summary workspace of the asset in which you want to create a PRD Component.

    -or-

    Access the Corrosion Loop in which you want to create a PRD Component.

  2. In the left pane, select , and then select Create New Component.

    The Create New RBI Component window appears.



  3. Enter values in the following fields:
    • Asset: This field is automatically populated with the asset for which you are creating a PRD Component.
    • Component Family: Select the component family for the Component that you want to create.
    • Component Type: Select the component type for the PRD Component that you want to create.
  4. Select Create.

    A new PRD Component is created, and is automatically linked to the selected Asset and the Corrosion Loop. The Component Details section appears, displaying the component datasheet.



  5. Enter values in the available fields.
  6. In the upper-right corner of the datasheet, select .

    The changes made to the PRD Component are saved.

What To Do Next

Apply a PRD Component

About This Task

When you apply a PRD Component, you make a copy of the original record. The applied PRD Component is not automatically linked to the original RBI Component's Corrosion Loop. Instead, the applied RBI Component can be linked to the same or a different asset and then to a Corrosion Loop.

Important: To distinguish PRD Components from RBI Components in a Corrosion Loop, PRD Components have the icon before the Component ID. All PRD Components function the same way as RBI Components.

Procedure

  1. Access the PRD Component that you want to apply.
  2. In the upper-right corner of the page, select .

    The Hierarchy Finder window appears.



  3. Navigate through the Hierarchy Finder to select the asset to which you want to apply the PRD Component.
  4. Select OK.

    The PRD Component is applied to the selected asset.

What To Do Next

Delete a PRD Component

About This Task

Important: To distinguish PRD Components from RBI Components in a Corrosion Loop, PRD Components have the icon before the Component ID. All PRD Components function the same way as RBI Components.

Procedure

  1. Access the Asset Summary workspace of the asset that is linked to the PRD Component that you want to delete.

    -or-

    Access the Corrosion Loop that is linked to the PRD Component that you want to delete.

  2. Next to the Component what you want to delete, select the check box next, and then select .

    A message appears, asking you to confirm that you want to delete the selected PRD Component.

  3. Select Yes.

    The PRD Component is deleted, and all links to existing related entities are removed.
