Overview
EN 4810:2017 is a European Standard developed by CEN and ASD-STAN, specifying the characteristics and technical requirements of gasket seals with a nickel alloy C seal on heat-resisting steel plates. This standard focuses on flange couplings with 3 fastening holes, designed specifically for inch series pipe couplings used in aerospace applications. The gasket seals are engineered to ensure reliable performance under high pressure and extreme temperature conditions, complying with stringent aerospace industry demands.
Key specifications include:
- Nominal pressure ratings up to 21,000 kPa (pressure dependent on tube material and thickness per EN 4814)
- Operating temperature range from -55 °C to 600 °C
- Material and surface treatment requirements to optimize corrosion resistance and mechanical integrity
- Single-use assembly guideline, prohibiting reuse after disassembly
EN 4810:2017 supports safety, durability, and quality management principles critical to aerospace fluid systems.
Key Topics
Materials:
- Plate material conforms to EN 3480 (steel FE-PA3601, air melted, softened) or EN 3488 (sheet and strip of the same steel)
- Nickel alloy C seals comply with EN 2407, providing excellent heat resistance
- Surface treatment includes passivation per EN 2516 and nickel plus chromium coatings following ISO 1456 to enhance corrosion resistance
Design and Dimensions:
- Flange plate with three equally spaced fastening holes sized for inch series
- Dimensional tolerances provided for hole diameters, radii, thickness, and overall sizes to ensure interchangeability
- Mass estimation for batch processing and inventory management
Assembly:
- C seal is inseparable from the heat resisting steel plate post-assembly, requiring careful handling to prevent damage
- Assembly guidelines reference TR 4815 for flange coupling installation best practices
- Intended for single use; disassembled gasket seals must be discarded to maintain sealing integrity
Marking and Identification:
- Marking follows EN 2424 standards for aerospace product traceability
- Markings are non-embossed to avoid compromising the component surface
Quality Assurance:
- Manufacturers must be approved under aerospace quality management standards such as EN 9100
- Compliance ensures that products meet reliability and performance demands for aerospace fluid systems
Applications
EN 4810 gasket seals are vital components in aerospace flange coupling systems used in hydraulic, fluid, and fuel lines where secure, leak-proof joints are essential. Their heat resistance and durability make them suitable for:
- Commercial and military aircraft hydraulic piping
- High-pressure aerospace fluid systems
- Fuel system connections requiring resistance to temperature extremes and pressurized environments
- Aerospace maintenance and repair operations that rely on standardized, certified sealing components
By adhering to EN 4810, aerospace manufacturers and maintenance organizations ensure compatibility, safety, and traceability of critical sealing elements within complex fluid systems.
Related Standards
Several key standards complement EN 4810 for a comprehensive aerospace flange coupling and sealing system:
- EN 4814: Technical specifications for flange couplings up to 21,000 kPa (inch series)
- EN 4816: Technical specification for gasket seals with nickel alloy C seals (inch series)
- TR 4815: Design standard providing assembly instructions for flange couplings
- EN 2407: Defines the nickel alloy used for heat-resistant seals
- EN 3480 & EN 3488: Specifications for steel materials used in flange plates
- EN 2516: Passivation requirements for corrosion-resistant steels
- EN 2424: Aerospace product marking and traceability
- EN 9100: Quality management system requirements for aviation, space, and defense organizations
- ISO 1456: Electrodeposited coatings of nickel and chromium for surface treatments
Together, these standards ensure well-integrated aerospace fluid system components that meet high performance and safety benchmarks.
