Overview

EN 3080:2006 defines the characteristics of tees, reduced, branch with thrust wire nut, for pipe coupling 8°30' in titanium alloy used in aerospace applications. It covers mechanical configuration, dimensional series, masses, marking and technical specification for couplings rated to a nominal pressure up to 28 000 kPa and a temperature range −55 °C to 135 °C. The standard targets reliable, lightweight titanium fluid-system fittings in aerospace platforms.

Key topics and requirements

• Scope and ratings: Tees for pipe coupling 8°30' in titanium alloy; pressure up to 28 000 kPa; temperature −55 °C to 135 °C.
• Configuration & dimensions: Detailed dimensional series, drill depths and across‑flat sizes are given (Figures and Tables define connections 1, 2, 3). Connections 1 and 3 shall be ≤ connection 2. Mass per connection is tabulated for selection and total mass calculation.
• Threading and sealing: Uses MJ thread limits per ISO 5855-3 and geometric configurations per EN 3274 / EN 3273 for dynamic beam seals.
• Materials: Titanium alloy references (EN 3311 / EN 3312 / EN 3314 / EN 3315 - TI‑P64001 variants including annealed, grade 2, solution treated and aged) are specified for forgings and bars.
• Surface finish & treatment: Internal surface radius R = 0.3–1.0 mm; surface roughness requirements; no hand deburring permitted. Lubrication on threads, sealing faces and thrust wire contact as per EN 2491. Thrust wire and nut elements referenced to EN 4032 and EN 3264.
• Marking & designation: Marking per EN 2424 (style A). Standardized designation format (EN3080-code1 code2 code3) and optional identification codes are provided.
• Acceptance & technical specification: Qualification and acceptance follow EN 3275, type II.

Applications

EN 3080:2006 is intended for aerospace fluid systems where high strength-to-weight fittings are required-such as hydraulic, pneumatic and fuel distribution systems on aircraft and spacecraft. The standard ensures interchangeability, traceability and predictable mechanical performance for titanium tees used in high-pressure, temperature-variable environments.

Who should use this standard

• Aerospace component designers and OEMs specifying pipe fittings
• Manufacturers and machinists producing titanium couplings and tees
• Quality, test and procurement engineers responsible for certification and part acceptance
• Maintenance and avionics teams selecting replacement fittings
