Single Unrestrained Metal Expansion Joint

Axial metal expansion joint with welding ends.

Single Unrestrained Metal Expansion Joint Description

The single unrestrained metal expansion joint (SSO, SFO and SGO) is mainly intended to absorb movements of axial expansion, both thermal and mechanical. In addition, to a lesser extent, it can absorb angular and lateral movements.

The single unrestrained metal expansion joint is composed of a single bellow of several U-shaped waves. These waves are made by one or more metal sheets longitudinally welded and hydraulically or mechanically-shaped.

Because of its configuration, the designer must bear in mind that these models transmit pressure stresses to the fixed points and guides of the piping system.
