(Main)Aerospace series - Flange couplings - Weld coupling, 90° elbow,in nickel alloy - Inch series
Aerospace series - Flange couplings - Weld coupling, 90° elbow,in nickel alloy - Inch series
This standard specifies the characteristics of straight welded coupling in nickel alloy for swivel flange
couplings for inch series aerospace applications.
Nominal pressure: The parts shall withstand nominal pressures given in Table 1. The nominal pressure of
the assembly depends on associated seal, tube material characteristics, tube diameter and tube wall
thickness (see EN 4814).
NOTE Assembly in accordance with TR 4815.
Luft- und Raumfahrt - Rohrverschraubung mit Flanschen - Schweißstutzen, Winkelstutzen 90°, aus Nickellegierung - Inch-Reihe
Diese Europäische Norm legt die Eigenschaften von gerade geschweißten Stutzen aus Nickellegierung für Rohrverschraubungen mit losen Flanschen in Anwendungen der Luft- und Raumfahrt (Inch-Reihe) fest.
Nenndruck: Die Teile müssen den Nenndrücken in der Tabelle 1 widerstehen. Der Nenndruck des Aufbaus hängt von der Dichtung, den Eigenschaften des Rohrmaterials, dem Rohrdurchmesser und der Dicke der Rohrwand ab (siehe EN 4814).
ANMERKUNG Aufbau nach TR 4815.
Série aérospatiale - Raccordement à bride - Raccord à souder, coude à 90°, en alliage de nickel - Série en inches
Aeronavtika - Prirobnične spojke - Varjena spojka, koleno 90°, iz nikljevih zlitin - Palčne mere
Ta standard določa lastnosti ravno varjenih spojk iz nikljevih zlitin za vrtljive prirobnične spojke za colsko izvedbo v aeronavtiki.
Nazivni tlak: deli morajo prenesti nazivne tlake, podane v preglednici 1. Nazivni tlak sestava je odvisen od povezanega tesnila, lastnosti materiala cevi, premera cevi in debeline stene cevi (glej standard EN 4814).
OPOMBA: Sestav v skladu s standardom TR 4815.
