EN 4802-2017 pdf download.Aerospace series – Flange couplings – Swivel flange with 3 fastening holes, in nickel alloy – Inch series.
This EN 4802 specifies the characteristics of swivel flanges, 3 holes, for flange couplings in nickel ahoy for inch series aerospace applications.
Nominal pressure: up to 21 000 kPa; depends on the associated seal, tube material, tube diameter and tube
wall thickness in the assembly (see EN 4814).
NOTE Assembly In accordance with TR 4815.
