Metallic expansion joints, besides acting as sections of a pipe, capable of withstanding the design temperatures, pressures, and media, also provide the flexibility that makes them necessary. That flexibility can be axial, lateral or angular. However, in many installations, some rigidity or structural strength is needed to support piping loads or to control the motion of the bellows and the pipe. Features are then added to the expansion joint to limit the modes or degrees of freedom, or the types of deflections, and to resist shear, or tension, or compression loads and/or bending moments.

FUNCTIONS and ADVANTAGES:
- Motion compensation.
- Expansion compensation.
- Eliminates pressure thrust forces.
- Anti-vibration and noise damping properties.
- Efficient in absorbing thermal deflections.

Metallic expansion joints are an ideal solution for expansion joint and oscillation challenges posed by modern piping system construction projects. Economical, safe and compact.

Metallic expansion joints have played an important role in these areas for many years: mechanical engineering, building technology, chemical industry, gas and water utilities, emission control technology, plant and ship construction as well as in power plant engineering.
