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.

Real Curved Surfaces Diameter (dG0)

Adapted from Figure 3, EN 1591-1:2001+A1, Flanges and their joints - Design rules for gasketed circular flange connections - Part 1: Calculation method

Defines dG0, the effective gasket diameter.

Gasket ID (dG1)

Adapted from Figure 3, EN 1591-1:2001+A1, Flanges and their joints - Design rules for gasketed circular flange connections - Part 1: Calculation method

Defines dG1, the inside diameter of the theoretical contact area of the gasket with the flanges.

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

Gasket OD (dG2)

Adapted from Figure 3, EN 1591-1:2001+A1, Flanges and their joints - Design rules for gasketed circular flange connections - Part 1: Calculation method

Defines dG2, the outside diameter of the theoretical contact area of the gasket with the flanges.

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

Material Type

Defines the gasket material category. Select Metallic or Non-Metallic.

Table Index

Defines the EN-1591 gasket properties table. The software uses the selected table only when you select Annex G (EN 1591-1:2001) as a flange pair property.

Gasket Type and Material

Defines the type of gasket and the material used. Select one of the following values:

  • Rubber

  • PTFE

  • Expanded PTFE

  • Expanded graphite without metal insertion

  • Expanded graphite with perforated metal insertion

  • Expanded graphite with adhesive flat metal insertion

  • Expanded Graphit and metallic sheets laminated in thin layers withstanding high stresses

  • Non-asbestos fibre with binder, eG < 1mm

  • Non-asbestors fibre with binder, eG >= 1mm

Axial Thk (eG)

Adapted from Figure 3, EN 1591-1:2001+A1, Flanges and their joints - Design rules for gasketed circular flange connections - Part 1: Calculation method

Defines eG, the thickness of the gasket.

Cross Sect Curve Radius (r2)

Adapted from Figure 3, EN 1591-1:2001+A1, Flanges and their joints - Design rules for gasketed circular flange connections - Part 1: Calculation method

Defines r2, the radius of curvature at the gasket cross-section.

Form Type

Defines the construction and shape of the gasket. Select Flat Gasket, Metal Gasket, Ring Joint Metal Gasket, or Metal Gasket W Curved Surfaces.

Sealing Face Inclination Angle (phiG)

Adapted from Figure 3, EN 1591-1:2001+A1, Flanges and their joints - Design rules for gasketed circular flange connections - Part 1: Calculation method

Defines jG, the angle of inclination of the sealing face, in degrees.

Numerical Constant for Gasket Type (c1)

Defines c1, the numerical constant for a gasket type, such as 1/20 for a fiber-based sheet gasket.
