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)
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.

About this task
before the Component ID. All PRD Components function the same way as RBI Components.Procedure
- 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.
- Select the Component Details tab.
The Component Details section appears, displaying the datasheet of the Component.
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.
before the Component ID. All PRD Components function the same way as RBI Components.Procedure
- In the left pane, select
, and then select Create New Component. The Create New RBI Component window appears.
- 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.
- In the upper-right corner of the datasheet, select
.The changes made to the PRD Component are saved.
Results
- The PRD Component inherits linked Potential Degradation Mechanisms from the RBI Corrosion Loop.

Link PRD Components to an RBI Corrosion Loop
About this task
This topic describes how to link existing PRD Components to an Asset or Corrosion Loop. You can also create a new PRD Component.
before the Component ID. All PRD Components function the same way as RBI Components.Procedure
- In the left pane, select , and then select Link Existing Component.
The Select RBI Components window appears, displaying a list of components in the same site that are not linked to a Corrosion Loop.
Results
-
The PDMs that are linked to the Corrosion Loop are linked to the PRD Components, in addition to the ones that are directly linked to the component.

A message appears, asking you to confirm that you want to unlink the selected Protected RBI Component.
Link Potential Degradation Mechanisms (PDMs) to a PRD Component
About this task
If the PRD Component is linked to a Corrosion Loop, then all the PDMs linked to the Corrosion Loop are also linked to the Component. You can, however, link additional PDMs to the Component.
This topic describes how to link one or more PDMs to a PRD Component. You cannot create PDMs; you can only link them. Therefore, a PDM must already exist to be linked to a PRD Component.
before the Component ID. All PRD Components function the same way as RBI Components.Procedure
- Select the Potential Degradation Mechanisms tab.
The Potential Degradation Mechanisms section appears, displaying a list of PDMs linked to the PRD Component.
- Select Add PDM.
A list of PDMs appears, displaying the methodology type of each PDM.
Tip: If you select the link that corresponds to a PDM, the PDM record appears in Record Explorer on a new page.

A message appears, asking you to confirm that you want to unlink the selected PDM.
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.
