Also known as the universal un-tied expansion joint. This type of Expansion Joint is made up of two bellows joined together by a central pipe provided with welding ends. The universal untied expansion joint with welding ends is made up of two bellows joined together by a central pipe.
Although it can be used to absorb any combination of the three basic movements it is mainly used to absorb large lateral movements.
The amount of lateral deflection that can be accepted is a function of the degree of angulation each bellows can absorb and the distance between the bellows or length of the central pipe.
It does not restrain pressure thrust so adequate anchors and guides must be provided and they can be used only in a piping systems that incorporate correctly designed anchors and pipe alignment guides.
Features
- Allow axial, lateral and angular movements
- Accept large amounts of lateral deflection
- Do not restrain pressure thrust
- Adequate anchors and guides must be provided
