Hinged Metal Expansion Joint
The main mission of the Hinged metal expansion joint (simple metal expansion joint for 1-axis for angular movement SSA and SFA) is to absorb angular expansion movements with rotation on a single axis both thermal and mechanical origin.
This hinged expansion joints or simple metal expansion joint for 1-axis is composed of a single bellow 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.

Hinged Metal Expansion Joints 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.
