# FCM Release 3.13B

Dec 2020

w-IMS FCM provides overall integrity status for flange connections: by managing critical flanges during assembly and disassembly; by identifying when and what to inspect on flange connections; and by following recommended practices in AMS RP 4-07.

Version 3.13B brings additional lookup based on materials and temperature, adjustment on speedy bolting pattern and target gasket stress.

## Lookup based on Material and Temperature

IMSFB-15226

To make defining flanges easier, FCM will now use lookup tables to suggest values for the following fields:

Based on Operating Temperature, Flange Material and Flange Thickness, FCM will suggest:

- Allowable Stress at Amb Temp
- Allowable Stress at Oper Temp
- Yield Stress at Oper Temp
- Yield Stress at Amb Temp

Based on Stud Size, Operating Temperature, and Stud Grade, FCM will suggest:

- Bolt Allowable Stress at Atm Temp
- Bolt Yield Stress at Amb Temp
- Bolt Allowable Stress at Design Temp

To be transparent about the suggested values, the lookup tables, which FCM uses, can be viewed in the application settings:

Note: For the fields with reference to the Ambient Temperature, FCM suggests values for the lowest temperature in the lookup table.

## Adjustments on Target Gasket and Bolt Stress

IMSFB-16898

To build on existing logic, FCM will use the following logic to suggest the Target Bolt Stress and the Target Gasket Stress:

1. If the Flange Size and the Class Rating are available, FCM suggests an AMS recommended value for the Target Bolt Stress.
2. If the Flange Size, or the Class Rating, is missing, the AMS suggestion will be unavailable. FCM will then suggest 70% of the Bolt Yield Stress, if available for the Target Bolt Stress.

Based on Target Bolt Stress, if all values are available, FCM calculates a suggested Target Gasket Stress with the following formula:

## Switching between Bolting Patterns on Protocol

IMSFB-17176

In contrast to the previous version, the Bolting Pattern can now be chosen on the protocol itself. On the Full Flange Protocol, you can choose between a **Regular** (4 step) Bolting Pattern and a **Speedy** (3 step) Bolting Pattern, by simply clicking the appropriate option.

In Settings, as was previously the case, a default Bolting Pattern can be defined, which will then be used when a condition history is created.
