Introduction to Fabric Expansion Joint

Fabric Expansion Joints consist of prefabricated bellows that are mainly flexible connections in air, flue gas pipes and exhaust duct systems found in all kinds of industries. These bellows are able to:

Absorb thermal expansions and vibrations
To hold parts together and to allow movements
To compensate misalignments

Applications of Fabric Expansion Joint:

Oil and Gas
Power
Steel
Chemical and Fertilizer
Cement
Defence and Railways
Water

Features of Fabric Expansion Joint

Able to withstand large movements in short length
Ability to absorb simultaneous movements easily in more than one plane
Very low forces required to move the expansion joint
Minimum Replacement Cost
Noise and Vibration Resistance
Ease of Installation

Design and Installation of Fabric Expansion Joint

There are several parameters required to design an Expansion Joint:

Internal Diameter
Design Pressure
Material of Bellows Element
Design Temperature

Key Benefits of Expansion Joint

Significant reduction of cold air ingress resulting in improved furnace efficiency.
Withstand temperatures of up to 1370°C.
Allow unrestricted movement of the tubes while maintaining complete seals.
Reduce the possibility of tube damage due to rapid quenching
Cost effective with very fast payback on investments.
Block radiant heat loss.
Personnel safety enhancement.
