  • C = Diameter of Raised Face
  • H = Height of Raised Face
  • E = Outside Diameter of Neck
  • K = Flange thickness
  • M = Length of Flange
  • N = Length of right end
  • F = Neck Diameter
  • R = Radius of Corners
  • D = Wall thickness

General notes..

  • Dimensions are in millimeters unless otherwise indicated.
  • Butt-weld ends (must be specified when ordering) DIN 3239-1-R6 edge form 22 to DIN 2559 (DIN EN ISO 9692)

Special notes..

  • Hex bolt lengths and diameters and lengths of Stud Bolts are calculated by the author of this website.
  • All lengths are calculated without washers, spring washers etc. and free threads (equals 1/3 time bolt diameter)
  • All lengths are calculated with a gasket thickness of 3 mm.
  • The dimensions of the bolts are calculated for the type 11 weld neck flange. Other types of flanges can be have different bolt hole diameters and thicknesses, so that the bolts even can have different dimensions.

Note 1.. ISO 7005-1 (steel flanges) PN 20, 50, 110, 150, 260, 420 are designed to be interchangeable with ASME B16.5 and MSS SP-44 flanges - ISO 7005-1 flanges are not identical to ASME B 16.5 and MSS SP 44 flanges but are deemed to comply with the dimensions specified in the ASME B 16.5 and MSS SP 44.

ISO 7005-2 (cast iron) flanges PN 20, 50 are designed to be interchangeable with ANSI/ASME B16.1 (gray cast iron) and B 16.42 (ductile cast iron) but they are not identical. They are deemed to comply with dimensions specified in ASME B16.1 (grey cast iron) and B 16.42 (ductile cast iron).

Note 2.. ISO PN 2.5, 6 do not have a corresponding ASME class and ASME Class 75, 400 and 800 do not have corresponding ISO PN designation. The use of these PN and Class flange ratings are therefore not recommended.
