Aerospace series - Flange couplings - Weld coupling, 90° elbow, in heat resisting steel - Inch series
This European Standard specifies the characteristics of straight welded coupling in heat resisting steel 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.
