EN 1092-1 is a European standard that specifies the requirements for carbon steel plate flanges, covering circular flanges used with pipes, valves, fittings, and accessories. The standard includes various flange types, such as flat face flanges, raised face flanges, ring-type joint flanges, and blind flanges, each suited for different industrial applications. The carbon steel grades commonly used for these flanges include P235GH, P265GH, and P355GH, selected based on their mechanical properties and suitability for various temperature and pressure conditions. Flanges are classified according to their nominal pressure (PN) ratings, such as PN 6, PN 10, PN 16, PN 25, PN 40, PN 63, and PN 100, indicating their maximum operating pressure and their pressure-temperature ratings based on material and design. EN 1092-1 also specifies dimensions, thicknesses, and bolt hole sizes to ensure proper alignment and sealing with connected equipment. The manufacturing process adheres to tolerance requirements to ensure dimensional accuracy and surface finish for proper gasket sealing. Flanges are used in piping systems, industrial equipment, and pressure vessels. Manufacturers often provide certificates of compliance or test reports to verify that the flanges meet EN 1092-1 standards, ensuring their quality and performance for various industrial applications.
