  2. Metal expansion joint - Wikipedia

    en.wikipedia.org/wiki/Metal_expansion_joint

    The single-plane or multi-plane piping system is subdivided into straight sections by fixed point in such a way that each section can be compensated by a single axial expansion joint. The fixed points must be designed to withstand the pressure and spring forces of the axial expansion joint, the frictional forces of the pipe guides and the flow ...

  3. Expansion joint - Wikipedia

    en.wikipedia.org/wiki/Expansion_joint

    An expansion joint is designed to allow deflection in the axial (compressive), lateral (shear), or angular (bending) deflections. Expansion joints can be non-metallic or metallic (often called bellows type). Non-metallic can be a single ply of rubberized material or a composite made of multiple layers of heat and erosion resistant flexible ...

    Hinged Expansion Joint - U.S. Bellows, Inc. They include hinges, attached to the expansion joint ends with a pair of pins, which allow angular movement in a single plane, restrain the pressure thrust, and prevent the expansion joint from deflecting axially, either in extension or compression.

    The standards are a combination of a variety of expansion joint manufacturers' knowledge and experience. [2] [3] The EJMA organization performs extensive technical research on a variety of topics concerning the design and manufacturing of expansion joints. [4] This knowledge contributes to providing new versions of the EJMA book of standards.

  6. Toroidal expansion joint - Wikipedia

    en.wikipedia.org/wiki/Toroidal_expansion_joint

    Toroidal Expansion Joint - U.S. Bellows, Inc. A Toroidal expansion joint is a metallic assembly that consists of a series of toroidal convolutions which are circular tubes wrapped around pipe ends or weld ends and have a gap at the inside diameter to allow for axial stroke while absorbing changes in expansion or contraction of the pipe line. [1]

  7. Breather switch - Wikipedia

    en.wikipedia.org/wiki/Breather_switch

    A breather switch, expansion joint, or adjustment switch is an intentional gap in railway tracks to allow for thermal expansion in long sections of otherwise unbroken rail. . They are placed between very long sections of continuous welded rail or at the transition from continuous welded rail to jointed track, and commonly in the vicinity of bridges, viaducts and tunnels where the ...
