EN 1092-1 is part of the European EN 1092 standard series and defines the technical specifications for circular flanges. It covers dimensions, facing types, pressure ratings, and connection details for flanges used in piping systems.

Key Features:

• Scope: Applicable to circular flanges such as weld neck, flat, blind, and lap joint types
• Pressure ratings: PN 2.5, PN 6, PN 10, PN 16, PN 25, PN 40
• Material compatibility: Suitable for carbon steel, stainless steel, alloy steels, and other materials
• Facing types: Includes flat face (FF), raised face (RF), and ring-type joint (RTJ) surfaces
• Size range: Covers flanges from DN 10 to DN 4000
  
  

Purpose and Benefits:

• Promotes standardization and compatibility across piping systems in Europe
• Provides a reliable reference for leak-tightness and mechanical strength
• Serves as a design and selection guide for manufacturers and engineers
