Published EN 1092-1 dimensions for every PN10 size in this product family.

Dimensions in millimetres. Bolt hole diameter applies to through-holes. For stud length, gasket and bolting selection, match the gasket and bolts to EN 1092-1.

What PN10 means in service

PN10 is a nominal pressure of 10 bar (1 MPa) at ambient temperature for EN material group 1, derating with temperature per EN 1092-1.

EN 1092-1 uses PN (nominal pressure) ratings in bar: PN6, PN10, PN16, PN25 and PN40. PN16 means 16 bar nominal at ambient temperature for EN material group 1, derating with temperature per the EN 1092-1 tables. EN PN ratings are not equivalent to ASME classes in dimensions, even where the pressure looks similar.

Facing and materials

Raised face (RF) with a 2 mm face height is standard; flat face (FF) and groove (tongue) facings are available.
