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.
