General Information
Relations
Overview
EN 1092-3:2003 is the CEN European Standard that specifies requirements for circular copper alloy flanges and copper-alloy collars used with loose steel plate flanges. It covers PN-designated flanges from PN 6 to PN 40 and nominal sizes DN 10 to DN 1800, and applies to flange types shown in the standard (plate, weld-neck, slip-on, blank, collars, integral flanges, etc.). The standard defines dimensions, tolerances, materials and their associated pressure/temperature (p/T) ratings, flange facings and surface finish, weld repairs, marking, and guidance on bolting, gaskets, installation and approximate masses.
Key Topics
- Scope & compatibility
- Applies to copper alloy flanges and collars intended for attachment to copper or copper-alloy tubes (per EN 12449). Use with tube sizes from EN 1057 requires agreement between manufacturer and supplier.
- Non-gasketed pipe joints are excluded.
- Flange types
- Includes plate flanges, loose plate + collar combinations, weld-neck, slip-on, blank (including steel-clad joint face), hubbed types and integral flanges.
- Dimensions & tolerances
- Standardized mating dimensions for PN 6, 10, 16, 25, 40 and DN range; tolerances and bore options are specified for interchangeability.
- Materials & identification
- Lists acceptable copper-alloy materials and requires traceability/identification; certificates (EN 10204) may be required by the equipment manufacturer.
- p/T ratings
- Provides material-based pressure/temperature ratings; when mating flanges differ, the lower p/T rating governs the joint.
- Fabrication, welding & repairs
- Welding repair procedures and filler materials must ensure mechanical and metallurgical integrity; heat treatment where required.
- Bolting & gaskets
- Guidance on selecting bolting materials and referencing relevant gasket dimensions (EN 1514); bolting selection must suit design temperature, pressure and flange materials.
- Marking & documentation
- Requirements for marking flanges and information to be supplied by equipment manufacturers (Annex A); installation guidance in Annex B; mass tables in Annex C.
Applications & Users
EN 1092-3:2003 is used by:
- Flange and collar manufacturers producing copper-alloy components
- Pipe, valve and fitting equipment manufacturers specifying flange connections
- Piping designers, HVAC/plumbing contractors and procurement teams requiring PN-designated copper-alloy flanges
- Project engineers in industries where copper alloys are preferred (potable water, HVAC, marine, industrial services) Use of this standard ensures dimensional interchangeability, correct material selection and safe p/T performance for copper-alloy flanged joints.

The article discusses the European Standard EN 1092-3:2003, which specifies requirements for circular copper alloy flanges and copper alloy collars combined with loose steel plate flanges. The standard covers flanges with PN designations from PN 6 to PN 40 and nominal sizes from DN 10 to DN 1800.
