EN 3245:2001 - Aerospace series - Pipe coupling 8°30' in titanium alloy - Unions, straight, reducer

Overview

EN 3245:2001 (CEN) defines the characteristics and technical requirements for straight unions, reducer used with pipe coupling 8°30' in titanium alloy for aerospace fluid systems. Developed under AECMA and adopted by CEN members, the standard targets components rated to a nominal pressure of up to 28 000 kPa and an operating temperature range of -55 °C to 135 °C. It ensures compatibility, interchangeability and safe performance within specified aerospace system limits.

Key Topics

  • Scope and purpose: Specifies geometry, material, surface finish and marking requirements for straight reducer unions intended for 8°30' pipe couplings.
  • Materials: Titanium alloy requirements reference EN 3311 and EN 3314 (titanium alloy TI-P64001 in specified bar forms).
  • Dimensional and configuration control: Dimensions and configuration conform to the figures and tables in EN 3245 and related documents (EN 3274 for thread-end geometric configuration).
  • Surface treatment and lubrication: Threads and sealing faces require lubrication per EN 2491. Surfaces must be abrasive blasted with non‑metallic grit before lubricant application; specified film thickness is 0.005 mm to 0.013 mm.
  • Marking and identification: Marking follows EN 2424 (style A) and includes the standard identity and code format for unions, reducer.
  • Qualification and acceptance: Where not otherwise specified by the purchaser, dimensions and performance must meet qualification and acceptance conditions of EN 3275, type II.

Applications

EN 3245:2001 is intended for aerospace engineers, procurement specialists and quality teams working on fluid systems that require:

  • High-strength, corrosion-resistant fittings using titanium alloys for weight-critical aircraft and spacecraft plumbing.
  • Interchangeable unions in hydraulic, fuel or pneumatic lines where the 8°30' pipe coupling is specified.
  • High-pressure systems up to 28 000 kPa and environments spanning low to moderate temperatures (-55 °C to 135 °C).

Practical benefits include ensured dimensional compatibility across manufacturers, documented surface-preparation and lubrication practices for sealing reliability, and harmonized marking for traceability.

Related Standards

Relevant normative references incorporated by EN 3245 include:

  • ISO 5855-3 - MJ threads limit dimensions for fittings for fluid systems
  • EN 2424 - Marking of aerospace products
  • EN 2491 - Molybdenum disulphide dry lubricants - coating methods
  • EN 3274 - Pipe coupling 8°30' thread-end geometry
  • EN 3275 - Pipe coupling 8°30' dynamic beam seal; technical specification (qualification & acceptance)
  • EN 3311 / EN 3314 - Titanium alloy TI-P64001 material specifications

Use EN 3245 when specifying or procuring straight reducer unions for 8°30' titanium-alloy pipe couplings to ensure compliance with recognized aerospace component practices and to facilitate safe, reliable system integration.
