Axial bellows expansion joints are engineered piping components designed to absorb axial movement?compression and extension?in pipelines caused by thermal expansion, pressure, and vibration. They consist of a flexible, high-grade metal bellows (typically stainless steel) with end connections, offering a compact, efficient solution for preventing structural stress in piping systems.
Key Features and Characteristics
Movement Absorption: Primarily designed for axial movements, though they can handle minor angular or lateral movements.
Design & Components: Comprised of a single or double-metal bellows element and connecting fittings like welding ends or flanges (fixed or floating).
Materials: Fabricated from high-grade stainless steel (304, 316, 321) or special alloys to ensure durability.
Operating Limits: Suitable for high-temperature and high-pressure conditions.
