What is BS EN 4808 - Flange couplings in nickel alloy about?
BS EN 4808 is one of a series of documents applicable to the specifications of straight welded coupling in nickel alloy. BS EN 4808 specifies the characteristics of straight welded coupling in nickel alloy for swivel flange couplings for inch series aerospace applications.
Note 1: Nominal pressure: The parts shall withstand nominal pressures given in BS EN 4808. The nominal pressure of the assembly depends on the associated seal, tube material characteristics, tube diameter, and tube wall thickness (see EN 4814).
Note 2: Assembly in accordance with TR 4815.
Who is BS EN 4808 - Flange couplings in nickel alloy for?
BS EN 4808 on flange couplings - weld coupling, 90° elbow, in nickel alloy is useful for:
- Aerospace products manufacturers
- Aeronautical engineers
- Testing agencies involved in the inspection of aerospace products
- Quality assessing engineers
Why should you use BS EN 4808 - Flange couplings , in nickel alloy?
Flange coupling involves bringing the two tube ends together in a flush, sealed manner. The two-piece coupling unit consists of a keyed receiving side for the flanged end to be fastened. The reason being it may be married to the opposing tube end, which also has a flanged end.
A flange coupling is useful in pressurizing the piping systems where tubing ends or two pipes need to come together.
BS EN 4808 provides requirements for the configuration, dimensions, tolerances, masses, material, and surface treatment of flange couplings. BS EN 4808 also specifies the designation, the identification marking, technical specifications, and quality assurances of flange couplings
