PEI CMLs - Details Page

To open a CML Details Page, click on the desired CML Name hyperlink in the Circuit main screen (or on any other screen). See IMS Details Page.

The CML Details Page can be divided into sections:

Header

The header of the detail page shows the Circuit name / Circuit ID to which the CML belongs, followed by the CML name / CML ID, separated by a dash (“-”), along with various navigation options.

For more information on the icons, see IMS Details Page.

Details

The fields listed in this section are described in Creating new PEI CMLs.

Deleting CMLs

To delete a CML:

Go to the CML Details Page (see IMS Details Page).
In the Details section, click Edit.
Uncheck the Active checkbox to make the CML Inactive.
Click Save.
The Delete button will now also appear in the Details section. Note: If you cannot see the Delete button, refresh the page.
Click Delete.
A pop-up will ask you to confirm. Review the details and click OK (or Cancel).

A pop-up message will appear stating that the deletion of the CML was successful.

Calculating Renewal Thickness using TMIN Calculators

From the Details section, you can calculate the Minimum Required Thickness (TMIN) for Components subjected to Internal pressure. If a TMIN calculator is configured under Settings \ Maintenance \ Configuration \ Configuration per Hierarchy Type for the applicable Equipment group-CML Type combination (see Hierarchy Type Configuration in Settings), a disabled TMIN Calc button will appear next to the CMLs Renewal Thickness field, indicating that the TMIN calculator is available for this CML. Note: The Calculator can only be used in Edit mode.

Disabled TMIN Calc button indicating that the Calculator is available for the CML.

To calculate the Renewal Thickness using the TMIN calculator in CML Details, you will need to enter in the Edit mode:

Click Edit. Note: When you enter Edit mode, the TMIN Calc button will become enabled.
Click the TMIN Calc button.
If multiple TMIN calculators are available, select the relevant one from the drop-down menu.

Select the applicable TMIN calculator from the drop-down menu.

Enter the required data. See the table below.
Click Calculate.

Calculated Minimal Required Thickness will be displayed below the calculator.

To perform another calculation, reset the calculator by clicking Reset.

The table below describes the parameters necessary for the calculators:

Item	Description
Internal Design Pressure (P)	The maximum expected operating internal pressure (in bar or psi) that the equipment must safely withstand.
Inside Radius (R)	The radius measured on the inside surface of the pressure boundary for the specific equipment or component.
Maximum Allowable Stress (S)	The allowable stress value from the material specifications or design code for your equipment in bar or psi.
Joint Efficiency (E)	The joint efficiency factor (0 < value ≤ 1) based on the weld type and inspection quality of your equipment’s welded joints.
Outside Diameter (D)	The total external diameter of the pressure boundary for the specific equipment or component, in mm or inches.
Inside Spherical or Crown Radius (L)	The internal radius of the spherical portion or crown of the vessel/head, in mm or inches.
Coefficient	The coefficient representing the effect of the bend or elbow geometry on stress or pressure loss.
Bend Radius of Welding Elbow or Pipe Bend (R1)	The radius of the bend as the centerline radius of the elbow or pipe bend in mm or inches.

To learn more about the calculation, see Minimum Wall Thickness (TMIN) Calculations.

Applying the Calculated Minimum Required Thickness

Once the Minimum Required Thickness is calculated by using the TMIN calculator from the CML Details page, you can apply it to the CML.

To apply the calculated Minimum Required Thickness value to the CML, click Apply.

On the CML Details page, the calculated Renewal Thickness will be displayed, and the Renewal Basis will be changed to “CALCULATED”. An Info button will appear next to the Renewal Basis value. Hovering over the Info button next to the Renewal Basis value will reveal data related to when and who performed the calculation, as well as which calculator was used.

Click Save.

A warning will appear indicating that saving the data will trigger a recalculation of the Circuit.

Click OK or Cancel.

Measurement Positions

In the Measurement Positions section, you can view, edit, add, or delete Measurement Points (MPs), which are specific locations on Equipment or Piping where Wall Thickness measurements need to be taken. These points mark precisely where inspection data is collected. Multiple MPs can exist within a single Condition Monitoring Location (CML). When requesting Wall Thickness measurements, you need to select a Measurement Set (MSET), which is a collection of MPs on the Equipment.

Measurement Positions Toolbar

The Measurement Positions section is used to create and maintain the applicable CMLs for the selected Circuit. The grid shows a toolbar that can be used to do so.

CML toolbar:

Icon	Action	Description
	Save	Save changes you made in the editable grid (such as Renewal Thickness, Diameter or Nominal WT).
	New	Create a new MP, which opens a new screen in which data for the new MP should be populated. Or
	Delete	Delete an Existing MP.
	Export
	Copy	Copy a selected CML.
	Paste	Paste the copied CML as a new CML, measurements are not copied.
	Move	Move (copy) CMLs to another Circuit. This way you can also move (copy) old wall thickness measurements to a "new Equipment". Note: A recalculation will happen at both the origin and destination Circuit.
	Select New Predefined MP	Opens the registered MPs for the CML and allows you to directly add other Measurement Point(s).
	Show only selected	Check to show only the selected rows.

Adding Measurement Points to the CML

On the CML Details page, MPs can be created automatically and manually.

If an MP Configuration is assigned to the CML during creation, the MPs are generated automatically and migrated to the Pre Defined MPs (PDMPs) according to the selected configuration.

If an MP Configuration is assigned to an existing CML during editing, the Predefined Measurement Points in the Measurement Positions section will not be created automatically. To migrate the MPs to the PDMPs:

Navigate to the Measurement Positions section.
Click Migrate to convert MPs to PDMPs.

Click Save in the Toolbar.

Creating New Measurement Points on a CML

To create a new Measurement Point manually:

Click the Plus button.
Select the MP Name.
If Matrix Locations for the CML Type have been defined in the Settings, select the Location.
The Pre Def MP Name will be generated automatically.
Click Save.

Copying and Pasting Measurement Points Measurements

You can copy the data, such as Nominal WT, Diameter, and Renewal Thickness, from one PDMP and paste it into another PDMP within the same CML. It is not possible to copy PDMPs from one CML to another.

To copy the data from an MP:

Select the relevant PDMP you want to copy the data from. Note: You can copy one MP at a time only.
Click Copy in the toolbar.

Select a PDMP and click Copy to copy the data from the PDMP.

Unselect the copied PDMP.
Select a different PDMP to which you want the data to be pasted. Note: You can paste only to PDMDs that have the Inherit checkbox unchecked.
Click Paste.

Select a different PDMP and click Paste.

The Data, like Nominal WT, Diameter, and Renewal Thickness, will be pasted to the selected PDMP.
