Overview
EN 3857:2002 specifies the characteristics of welded 90° elbows for aerospace pipe couplings, 60° spherical, manufactured in titanium alloy TI‑P64001. Intended for aerospace fluid systems and components, the standard covers configuration, dimensional requirements, material reference, designation, marking and quality assurance for these welded elbows. Assembly guidance is given by TR 4052.
Keywords: EN 3857:2002, aerospace pipe couplings, titanium TI‑P64001, welded 90° elbows, spherical 60°, aerospace standards.
Key topics and requirements
- Scope: Defines welded elbows 90° for 60° spherical pipe couplings in TI‑P64001 for aerospace use (assembly per TR 4052).
- Configuration, dimensions and tolerances: Detailed geometrical configuration, dimensions and tolerances are specified (figures and Table 1 in the standard). Dimensions and tolerances are given in millimetres.
- Material: Base material is titanium alloy TI‑P64001, with material properties referenced to EN 2530.
- Fitting ends: Welding and fitting-end geometry are covered; fitting ends follow EN 2656 requirements where applicable.
