Single Unrestrained Expansion joints
The Single Unrestrained metal axial expansion joints are made of one single bellows element with end connections.
Regardless of accessories, such as liners and covers, this model absorbs all of the movements in any one length of piping but it is mainly used to absorb axial movements.
It does not restrain pressure thrust so adequate anchors and guides must be provided and they can be used only in piping systems that incorporate correctly designed anchors and pipe alignment guides.
Features
- Absorbs axial, lateral, and angular movements
- Must be properly guided
- Does not restrain the pressure thrust
- Requires main and directional anchors
Axial Metal Expansion Joints Threaded

What are the key features of Single Unrestrained Expansion Joints?
The Single Unrestrained Expansion Joints are designed to absorb thermal expansion and contraction in piping systems. They are characterized by a single bellows element that allows for axial movement without any external restraints. This flexibility makes them suitable for applications where the piping system can freely move, accommodating thermal expansion and reducing stress on the system.
How do Single Unrestrained Expansion Joints differ from restrained types?
Unlike restrained expansion joints, which incorporate additional structural components to limit movement, Single Unrestrained Expansion Joints operate without restraints. This allows for greater freedom of movement and is particularly advantageous in systems where the thermal movements are predictable and can be managed without additional constraints. For applications requiring minimal resistance in movement, these joints are ideal.
In what applications are Single Unrestrained Expansion Joints typically used?
Single Unrestrained Expansion Joints are typically used in industrial piping systems where there are significant thermal expansions and contractions. Common applications include Axial Metal Expansion Joints Welding ends for steam lines, hot water systems, and various chemical processes. Their design allows them to efficiently handle the dynamic movements caused by temperature changes, ensuring durability and reliability in high-stress environments.
