Expansion Joint Lateral Deflection & Angular Deflection Lateral Deflection Lateral refers to the direction perpendicular to the centerline of the expansion joint(in any plane). Other terms for this deflection are PARALLEL OFFSET and TRANSVERSE. This movement occurs with both of the ends of the expan

Bellows Type Deflections --- Axial Deflection In order to properly apply expansion joints to piping systems, it is necessary that both the piping specialist and the expansion joint designer each understand not only how the piping flexes, but how the various expansion joint types function and what

Bellows DesignThe bellows is the flexible element of expansion joint.It must be strong enough circumferentially to withstand the pressure and flexible enough longitudinally to accept the deflections for which it was designed , and as repetitively as necessary with a minimum resistance. This strength

Characteristic of Bellows Designs Single Ply Typical Application * Shell and tube heat exchangers * Clamshell bellows * Penetration seals * HVAC piping Characteristics * One ply * Relatively thick * Robust * Higher spring rate * High lateral stiffness * Relatively cheap * Good NDE when installed

Characteristics of Bellows Designs Multi-Ply * Each ply made from welded tube * Each ply leak proof * Wetted ply can be made of different (higher alloy) material for enhanced corrosion resistance * Allowance for weep holes Multi-ply (Spiral)* Inner/Outer plies welded* No sudden leak* Wetted

There are introductions of types of movements will a rubber expansion joint handle and the function of a rubber expansion joint.That must be help you to learn more about a rubber expansion joint.

Will you confused what bellow expansion joint to select?We help you to handle the problem with this page.There are two main contents of a rubber expansion joint,including the advantages and the main components of the rubber expansion joints.

In modern expansion joints, the metal bellows expansion joints are often produced with a so-called multi-ply design. And multiple thin plies of metal are layered to form the bellows walls to increase both flexibility and stability.
