What is BS EN 4801 - 3 - Holes swivel flanges in heat resisting steel about?
The flange coupling is a driving coupling placed between rotating shafts. These shafts comprise a flange fixed on each shaft end, and are held and bolted together using a ring of bolts that complete the drive. These couplings are designed to seal two tube ends in a flush manner. 
BS EN 4801 specifies the characteristics of swivel flanges, 3 holes, for flange couplings in heat resisting steel for inch series aerospace applications.
BS EN 4801 determines the nominal pressure to be up to 21 000 kPa, depending on associated seal, tube material, tube diameter, and tube wall thickness in the assembly which can be seen in EN 4814.
Who is BS EN 4801 - 3 - Holes swivel flanges in heat resisting steel for?
BS EN 4801 for 3 holes swivel flanges for aerospace flange coupling in heat resisting steel is helpful for:
- Manufacturers of aircraft 
- Manufacturers, and suppliers of aerospace components 
- Product design engineers 
- The military sector 
- Quality control teams 
Why should you use BS EN 4801 - 3 - Holes swivel flanges in heat resisting steel?
BS EN 4801 provides you with the guidelines for the required configuration, design, dimensions, tolerance, and masses to ensure reliable, and accurate alignment of bolt holes with the swivel flange in heat resisting steel.
BS EN 4801 guidelines enable you to design, and manufacture high quality swivel flange with 3 fastening holes, in heat resisting steel that contribute to aviation safety, and quality.
