They consist of one or more , connectors at both ends, and tie rods that depend on the application. They are differentiated according to the three basic types of movement: Axial, angular and lateral expansion joints.
PTFE Expansion Joint is elastic vessel that can be compressed when pressure is applied to the outside of the vessel, or extended under vacuum. When the pressure or vacuum is released, the bellows will return to its original shape (provided the material has not been stressed past its yield strength).

Design

Flanges with through holes connect the standard bellows. Sizes are identical whatever the type of drilling of the item.

On request, the holes can be tapped.

The are fitted with standard flanges conforming to the type of drilling requested (PN or ANSI).

The flanges have PN 10, PN 16, ANSI 150 Ibs or ANSI 300 Ibs drilling and others on request.

The maximum operating pressure of the bellows and compensators must be in accordance with the respective pressure/

All bellows are PTFE lined.
