EN1092 1 Flange

EN 1092-1 is a European Standard for Flanges and their joints – Circular flanges for pipes, valves, fittings and accessories, PN designated. It specifies the requirements for circular steel and iron flanges in the range of nominal sizes between DN 15 and DN 4000 and PN 2.5 to PN 400, covering various pressure and temperature ratings. The standard also defines the dimensions, tolerances, materials, marking, and testing requirements for flanges used in pipelines, equipment, and other hydraulic and pneumatic applications.

EN1092-1 provides specifications for flange types that are commonly used in Europe. The standard includes dimensions and materials for various flange types, such as weld neck flanges, slip-on flanges, threaded flanges, and blind flanges.

EN1092-1 also provides specifications for the materials used in the construction of flanges. The most common materials used are carbon steel, stainless steel, and alloy steel. The choice of material depends on the application and the environmental conditions it will be exposed to. The standard also provides guidelines for the pressure and temperature ratings of the different flange types and materials
