EN 1092-1 flange dimensions — size chart and bolt patterns

EN 1092-1 is the harmonised European standard for steel pipe flanges, gradually replacing the national DIN 2632/2633/2527 tables. It sizes flanges by DN and rates them by PN, and identifies the flange shape by a type number — type 11 weld neck, type 05 blind, type 12 and 13 slip-on and type 01 plate flange.

For the same DN and PN, EN 1092-1 dimensions are generally compatible with the older DIN tables, but the type, facing and tolerance must still be confirmed. EN flanges are not interchangeable with ASME B16.5 flanges: bolt circles and hole counts differ even where the outside diameter looks the same. The PN6 range starts at DN10 in EN 1092-1, although some 2018 catalogues begin PN6 at DN15.

Dimensions are in millimetres. Bolt hole diameter is the through-hole and flange thickness excludes the raised-face height (2 mm for JIS and EN). Every size links to its own specification page with the material options, facing details and certification information. Raised face (RF) with a 2 mm face height is standard; flat face (FF) and groove (tongue) facings are available.

Matching the rest of the joint

A flange is only one part of the joint. The gasket, stud bolts and nuts must be selected to the same standard and facing, and the mating flange must be dimensionally identical. Raised face (RF) with a 2 mm face height is standard; flat face (FF) and groove (tongue) facings are available.

EN 1092-1 flanges are not interchangeable with other standard families — even where the nominal size and pressure rating look equivalent. Compare the bolt circle and bolt count before ordering, or read the standards comparison guide.

EN 1092-1 reference: ratings, materials and tolerances

The dimension tables above answer “will it fit”. These pages answer “will it hold, at what temperature, in which material, and how is it marked” — transcribed from the same edition and cited table by table.
