UNIVERSAL
Description
A universal expansion joint is made of two single bellows separated by a central pipe and with flanges. The main objective of this type of construction is to achieve a high capacity for absorption of axial and lateral movements. This capacity is a function of the design of the bellows and the length of the intermediate section. A longer length means greater capacity for absorption. Any possible expansion of the intermediate pipe is  also absorbed by the two bellows.
Characteristics and Properties
- Applicable for low pressures.
- Absorbs large lateral and axial movements.
- Allows angular movements.
- Does not retain the force of the pressure.
- Must be properly anchored and guided.
Does not resist the force of the pressure, and must be supported by fixed anchoring that is properly designed.
