Universal expansion joints

The universal expansion joint can absorb not only axial movements but angular and lateral movements as well. It consists of two metal bellows with an intermediate pipe and connectors on both sides.

As a special form of the axial expansion joint, the universal expansion joint has only a limited pressure resistance for stability reasons and, moreover, loads the adjacent pipe supports with the axial compressive force resulting from the internal pressure.

The universal metal expansion joints are usually used to compensate large axial and lateral movements at low pressure.


Frequently Asked Questions (FAQ)

What are the primary functions of a universal expansion joint?

A universal expansion joint is designed to absorb not only axial movements but also angular and lateral movements. It comprises two metal bellows connected by an intermediate pipe, allowing for flexibility and compensation of thermal expansions and contractions within piping systems.

How does a universal expansion joint impact adjacent pipe supports?

Due to its design, a universal expansion joint exerts an axial compressive force resulting from internal pressure, which can load adjacent pipe supports. This necessitates careful consideration in the design and installation of the system to ensure that the supports can handle these forces effectively.

What variations of universal expansion joints are available for different applications?

There are several types of universal expansion joints tailored for specific applications, such as Universal Unrestrained Metal Expansion Joints - welding ends and Universal Unrestrained Metal Expansion Joints - flanged. For applications requiring additional support, you can opt for Universal restrained Metal Expansion Joints - flanged or Universal restrained Metal Expansion Joints - welding ends, which incorporate tie rods to manage the forces more effectively.
