Creating Corrosion Loops

To create a CL:

• Go to the IMS Main Menu.
• Click Corrosion Loops to go to the Corrosion Loop Main Screen (Grid List).
• Click the Plus button to create a new CL.

Go to the CL main menu and click +.

 

• Enter the required data in the pop-up window. Note: Either a Plant ID or a Unit ID must be specified as parent.
  Take Note

  • If the CL is created on the Plant, it is not possible to edit the hierarchy later and change the Parent to the Unit. It can be assigned to the new Plant only. This means the Unit will not be displayed in the CL grid.
  • If the CL was created on the Unit, the CL grid will display both the Unit and the Plant. In this case, in the CL details, the Parent Unit can be changed to a different Unit.
  • It is not possible to edit the CL Hierarchy through the import. An import will create a new CL (with the same Name) if a different Unit or Plant is provided in the file. It is possible to create a CL with the same Name under a different Plant or Unit because the uniqueness combination is defined as Plant-Unit-Name. It is not possible to have a CL with the same Name under the same Plant/Unit.
• Click Save when done.
• In the Details section:
  • Click Edit.
  • You can use the Area field to show the CL’s location in map view.
  • If desired, select a Corrosion loop color (if specific color coding has been applied to marked-up P&IDs).
  • Select Connected loops, downstream of the flow direction, if applicable.
  • If not yet done, specify the Corrosion Loop Materials. Note: Later these materials will automatically be added when you create a Barrier of type M-Material Selection (see Defining the Barriers (and linking to IOWs)).

Specify the Corrosion Loop’s material designation.
