Flange Dimension Lookup

Opens the Flange Dimension Lookup dialog box, which allows you to define general flange properties for weld neck flanges. The software then fills in flange and gasket dimensions with the closest standard size. For more information, see Flange Dimension Lookup Dialog Box.

Sync Mating Flange

Copies all values defined for the primary flange to the mating flange and keeps the values synchronized. Clear this option to define different values for each flange. Sync Mating Flange only displays for the primary flange.

Flange ID (d0/d0m)

Adapted from Figure 8, EN 1591-1:2001+A1, Flanges and their joints - Design rules for gasketed circular flange connections - Part 1: Calculation method

Defines d0, the inside diameter of the flange ring or the outside diameter of the central plate of a blank flange.

If you use Flange Dimension Lookup , the software defines a value for this field.

Flange OD (d4/d4m)

Adapted from Figure 8, EN 1591-1:2001+A1, Flanges and their joints - Design rules for gasketed circular flange connections - Part 1: Calculation method

Defines d4, the outer diameter of the flange.

If you use Flange Dimension Lookup , the software defines a value for this field.

Flange Type

Defines the construction of the flange. Select one of the following options:

  • Integral G.3-4/3-6/3-7/3-8

  • Loose G.3-10

  • Blind G.3-9

  • Reverse G.3-5

See the figures that follow for example of each flange type.

Figures adapted from EN-13445-3:2014 (E), Issue 5 (2018-07)

Figure G.3-4 Integral hub-flange on a cylindrical shell

Figure G.3-6 Flange integral with a conical shell

Figure G.3-7 Flange integral with a spherical shell

Figure G.3-8 Slip-on weld flange

Figure G.3-10 Loose flange

Figure G.3-9 Blind (blank) flange with flat closure

Figure G.3-5 Reverse integral hub-flange on a cylindrical shell

Lap Joint Contact ID (d7min/d7minm)

Adapted from Figure 1, EN 1591-1:2001+A1, Flanges and their joints - Design rules for gasketed circular flange connections - Part 1: Calculation method

Defines d7, the diameter of the location of reaction between a loose flange and a stub or collar for a lap joint flange.

Material

Defines the flange material. Click to open the Materials dialog box. Select a material from the list.

Blank Flange Center Hole Diameter (d9/d9m)

Adapted from Figure 9, EN 1591-1:2001+A1, Flanges and their joints - Design rules for gasketed circular flange connections - Part 1: Calculation method

Defines d9, the diameter of a central hole in a blank flange.

Blank Flange Center Plate Wall Thk

Adapted from Figure 9, EN 1591-1:2001+A1, Flanges and their joints - Design rules for gasketed circular flange connections - Part 1: Calculation method

Defines e0, the wall thickness of the central plate of a blank flange.

Equivalent Axial Flange Thk

Adapted from Figure 9, EN 1591-1:2001+A1, Flanges and their joints - Design rules for gasketed circular flange connections - Part 1: Calculation method

Defines eF, the effective axial thickness of the flange.

If you use Flange Dimension Lookup , the software defines a value for this field.

Radial Pres Load Thk (eP/ePm)

Adapted from Figure 5, EN 1591-1:2001+A1, Flanges and their joints - Design rules for gasketed circular flange connections - Part 1: Calculation method

Defines eP, the part of the flange thickness subject to radial pressure loading.

For many flanges, eP and eF are the same value.

Connected Shell/Pipe Wall Inclination Angle (phis/phism)

Adapted from Figure 5, EN 1591-1:2001+A1, Flanges and their joints - Design rules for gasketed circular flange connections - Part 1: Calculation method

Defines jS, the angle of inclination of the connected shell wall, in degrees.

Raised Face Depth (Fd/Fdm)

Defines Fd, the thickness of the raised face of a spacer-seated flange.

Stub Collar OD (d8/d8m)

Adapted from Figure 10, EN 1591-1:2001+A1, Flanges and their joints - Design rules for gasketed circular flange connections - Part 1: Calculation method

Defines d8, the outside diameter of a stub or collar of a loose flange.
