EN 3244:2001 - Aerospace series - Pipe coupling 8°30' in titanium alloy - Unions, straight

Overview

EN 3244:2001 - "Aerospace series - Pipe coupling 8°30' in titanium alloy - Unions, straight" is a CEN standard that defines the characteristics and requirements for straight unions used with 8°30' pipe couplings in titanium alloy for aerospace applications. The standard covers dimensional configuration, materials, surface treatment and marking for unions designed to operate at nominal pressures up to 28 000 kPa and within a temperature range of −55 °C to 135 °C.

Key topics and requirements

  • Configuration and dimensions: Unions are specified by figure/table layouts (see table 1 in the standard); unspecified dimensions may be chosen by the manufacturer provided EN 3275 type II qualification/acceptance is met.
  • Threading: Uses MJ threads in accordance with ISO 5855-3 (limit dimensions for fittings for fluid systems).
  • Material: Titanium alloy per referenced specifications (EN 3311 / EN 3314 for TI‑P64001 in bar form).
  • Surface treatment and lubrication:
    • Abrasive blasting with non‑metallic grit prior to lubricant application.
    • Lubrication on threads and sealing faces per EN 2491 (molybdenum disulphide dry lubricant methods).
    • Specified lubricant film thickness: 0.005 mm to 0.013 mm.
  • Surface roughness: Defined in the standard (refer to figure 1) unless otherwise specified in design documentation.
  • Mass and sizing: Mass per piece and dimensional codes are provided (table 1) to support part identification and procurement.
  • Marking: Identification and marking are required according to EN 2424 (style A).
  • Technical specification: Acceptance and qualification follow EN 3275, type II.

Applications

EN 3244 is applicable to aerospace fluid systems and components where robust, lightweight, corrosion‑resistant pipe couplings are required. Typical practical uses include:

  • High‑pressure aerospace hydraulic and fluid lines (design and manufacture)
  • Structural fluid connections where titanium’s strength‑to‑weight and corrosion resistance are required
  • Replacement parts, maintenance and overhaul (MRO) for certified aircraft systems

Who should use this standard

  • Aerospace component designers and engineers specifying pipe couplings
  • Manufacturers and machine shops producing titanium unions
  • Quality, inspection and certification teams ensuring compliance with aerospace requirements
  • Procurement specialists and supply chain managers specifying parts for aircraft fleets
  • MRO organizations and technical documentation authors

Related standards

  • ISO 5855-3 (MJ threads)
  • EN 3274 (thread end geometric configuration)
  • EN 3275 (dynamic beam seal / technical specification)
  • EN 3311 / EN 3314 (titanium alloy TI‑P64001)
  • EN 2491 (dry lubricant coating methods)
  • EN 2424 (marking of aerospace products)

Keywords: EN 3244, pipe coupling 8°30', titanium alloy unions, aerospace fluid systems, MJ threads, nominal pressure 28 000 kPa, temperature −55 °C to 135 °C, TI‑P64001.
