Double Hinged Metal Expansion Joint
The main mission of the double hinged metal expansion joint (universal metal expansion joint for one plane USA and UFA) is to absorb angular and lateral expansion movements with rotation on a single axis both thermal and mechanical origin.
The double hinged metal expansion joint (universal metal expansion joint for one plane) is composed of two bellows of several waves in the form of “U”. These waves are made by one or more metal sheets longitudinally welded and shaped hydraulically or mechanically.
Due to its configuration, the designer must bear in mind that these models DO NOT transmit pressure stresses to the fixed points and guides of the piping system.

Double Hinged Expansion Joint Applications
The figure shows the use of two Hinged metal expansion joints to absorb the main thermal loads in a single plane “Z” type elbow.
Example of a Hinged metal expansion joint for vertical expansion differences between a line and a tank.
This illustration shows the use of a Hinged type metal expansion joint able to absorb a line’s thermal movements as well as the movements in a single plane of a connected equipment.
