Legend
D = Outside Diameter
k = Diameter of Bolt Circle
d2 = Diameter of Bolt Holes
d4 = Diameter of Raised Face
f = Height of Raised Face
d1 = Outside Diameter of Neck
b = Flange thickness
h1 = Length of Flange
h2 = Length of right end
d3 = Neck Diameter
r = Radius of Corners
S = Wall thickness
General notes:
- Dimensions are in millimeters unless otherwise indicated.
- Butt-weld ends (must be specified when ordering) acc. to DIN 3239-1-R6 edge form 22 to DIN 2559 (DIN EN ISO 9692)
Extra notes:
- Hex bolt lengths and diameters & lengths of Stud Bolts are calculated.
- All bolt lengths calculated without washers, spring washers etc. and free threads (equals 1/3 time bolt diameter).
- Gasket thickness considered 3 mm for bolt length calculations.
- The dimensions of the bolts are for the type 11 weld neck flange.
- Please not that other types of flanges can be have different bolt hole diameters and thicknesses, so that the bolts even can have different dimensions.
