Industrial Single Row Flat Fin Tube Axial Movement Metal Expansion Joint

Axial movement metal expansion joint in industrial applications

Metal expansion joints (also called compensators) are compensating elements for thermal expansion and relative movement in pipelines, containers and machines.

They consist of one or more metal bellows, 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.

The axial expansion joint absorbs movement in an axial direction.

Standard connectors of the axial expansion joint are welded ends, fixed flanges and loose flanges. Axial expansion joints are often equipped with a guiding tube on the inside of the metal bellows. This reduces the flow resistance and prevents damage caused by direct contact with the flowing medium.

Axial expansion joints, which can absorb large movements, frequently consist of two metal bellows and an inside or outside sleeve that protects against buckling under internal pressure.

For small nominal diameters, protective tubes prevent mechanical damage during installation and operation. Axial expansion joints are suitable for internal and external overpressure.

If pressure is applied to the outside of the metal bellows of axial expansion joints, the expansion joints permit very large axial movements in case of internal pressure in a pipeline.
