Material Data

The material data available to other components is now included in the Rated Flange window.

  • A new material default has been added for rated flange for both metric and customary units. Just as the other material defaults, this is located on the Materials tab under Tools > Defaults. It works the same way as the materials default for the other components. This default replaces both the material group default and the original material default for rated flange.
  • SA-105 is the default when the software is shipped.
  • The materials default for rated flange only allows selection of materials that are included in one of the following ASME references: B16.5 2003, B16.5 2009, B16.5 2013, B16.47 1996, B16.47 2006, and B16.47 2011.
  • The material search in the rated flange form only allows selection of materials that are included in the current active reference: B16.5 2003, B16.5 2009, B16.5 2013, B16.47 1996, B16.47 2006, or B16.47 2011.
  • Due to the material changes, designs patched from 2012.0 or an earlier version of DesignCalcs will not have a material set; in most cases the math can still run as the Material Group will still be set.

Default Settings

  • If the size is 24” or less and the host is a shell, head, reducer, or nozzle, the default type will be set to the selection in the ASME Flange Type field on the General tab under Tools > Defaults.
  • If the size is 24” or less and the host is a flange, the default type will be set to Blind.
  • If the size is greater than 24” and the host is a shell, head, reducer, or nozzle, the default type will be set to Weld Neck Series A or B based on the selection in the ASME Flange Series field on the General tab under Tools > Defaults.
  • If the size is greater than 24” and the host is a flange, the default type will be set to Blind Series A or B based on the selection in the ASME Flange Series field on the General tab under Tools > Defaults.

Flange Size

  • If the size of the host is less than or equal to ½”, the size will be ½”.
  • If the size of the host is over 58”, the size will be 60”.
  • If the size of the host falls on a rated flange size included in the B16 references, the flange will default to that size.
  • If the size of the host falls between sizes included in the B16 references,the flange will default to the larger of the two sizes.

Flange Class

Upon creation of a rated flange, DesignCalcs will attempt to find the optimal flange class. If an optimal rated flange cannot be determined, the flange will start at class 150.
