CAESAR II Version
11.0 (2019)

Specifies an untied universal expansion joint. This type of unit is similar to a single unrestrained expansion joint. It can absorb movement in all directions and normally has a much higher capacity for transverse (lateral) deflection than a single bellows. An untied universal expansion joint subjects the system to pressure thrust loads which must be designed for external to the expansion joint. Even when pressure is negligible, these joints can often be difficult to use in practice unless proper guiding of the thermal displacement protects the joint against unwanted movement.
