Overview
EN 3243:2001 defines the characteristics and requirements for welded ferrules with dynamic beam seal end used with pipe coupling 8°30' in titanium alloy for aerospace applications. The standard covers ferrule configuration, materials, surface finish, marking and technical acceptance criteria for service up to 28 000 kPa and temperatures from −55 °C to 135 °C. It is part of the aerospace series of standards intended for aerospace fluid systems and components.
Key topics and requirements
- Scope & limits
- Applicable to ferrules welded to coupling ends 8°30' in titanium alloy for aerospace use.
- Nominal pressure: up to 28 000 kPa.
- Temperature range:−55 °C to 135 °C.
- Configuration, dimensions and mass
- Geometry and mass values are specified by figure and table references in the standard (dimensions that are unspecified may be at manufacturer’s option provided EN 3275 qualification/acceptance is met).
- Materials
- Titanium alloy requirements reference EN 3311 (annealed) or EN 3314 (solution treated and aged) for material selection.
- Surface roughness
- Surface finish requirements are specified relative to the ferrule geometry and sealing face (referenced figures).
- Marking
- Marking format follows EN 2424 (style F plus manufacturing date or batch number; style G for alternative marking) and includes the EN 3243 identity block format.
- Technical specification and acceptance
- Qualification and acceptance testing requirements reference EN 3275, type II (dynamic beam seal end tests and inspection).
- Documentation
- Design, manufacturing and inspection documentation should reference the appropriate codes and the EN 3243 designation.
Applications and who uses it
- Intended for manufacturers, designers and quality engineers working on aerospace fluid systems and components where high-integrity pipe couplings are required.
- Typical users:
- Aerospace component manufacturers (ferrules, couplings)
- Aircraft systems design and installation engineers
- Procurement and quality assurance teams ensuring compliance with aerospace component standards
- Certification and maintenance organizations verifying part conformity
- Practical uses include welded coupling joints in high-pressure aerospace tubing assemblies where a dynamic beam seal is required for reliable sealing under thermal and pressure cycling.
