BS EN 14917 specifies the requirements for design, manufacture and installation of metal bellows expansion joints with circular cross-section for pressure applications with maximum allowable pressure greater than 0.5 bar.
Metal bellows expansion joints are used as parts in pressure vessels or piping components.
BS EN 14917 on metal bellows is relevant to:
In mechanical and industrial applications, an expansion joint is a mid-structure separation designed to relieve stress on building materials caused by building movement. BS EN 14917 informs you about the design, manufacture and installation of metal bellows expansion joints for pressure applications.
BS EN 14917 helps you with the classifications of expansion joints and its parts, which are designed according to the type of movements, which can be absorbed. Expansion joints are designed to withstand the specified pressure at the specified temperature.
BS EN 14917 covers the right manufacturing methods to ensure the expansion joint conforms to the design requirements. These test methods enable you to produce high-quality metal bellows, which are ideal for mechanical joints in pressure vessels or pipes, that efficiently absorb vibration and shock.
