Fabric expansion joints are versatile components used in various applications across different industries to accommodate movements, vibrations, and thermal expansion in piping systems. Here are some common applications of fabric expansion joints categorized by industry:

1. Power Generation:

   • Boiler Ducts: Fabric expansion joints are used in ducting systems of boilers to absorb movements caused by thermal expansion and contraction, as well as to isolate vibration and noise generated by boiler equipment.
   • Exhaust Systems: Fabric expansion joints are installed in exhaust systems of gas turbines, diesel engines, and other power generation equipment to absorb movements and vibrations, while also providing thermal insulation and noise reduction.

2. Petrochemical and Refining:

   • Process Piping: Fabric expansion joints are employed in process piping systems to accommodate movements resulting from thermal cycling, process upsets, and seismic events in petrochemical plants and refineries.
   • Flue Gas Systems: Fabric expansion joints are used in flue gas ducting systems to handle high temperatures, corrosive gases, and thermal expansion, providing flexibility and durability in demanding environments.

3. HVAC (Heating, Ventilation, and Air Conditioning):

   • Air Handling Units: Fabric expansion joints are installed in air handling units and HVAC ducting systems to absorb movements caused by thermal expansion and contraction, as well as to isolate vibration and noise.
   • Exhaust and Ventilation Systems: Fabric expansion joints are used in exhaust and ventilation systems of commercial buildings, hospitals, and industrial facilities to accommodate movements and vibrations while maintaining air quality and system integrity.

4. Industrial Processes:

   • Chemical Processing: Fabric expansion joints are employed in chemical processing plants to handle corrosive chemicals, high temperatures, and thermal cycling, providing flexibility and resistance to chemical attack.
   • Paper and Pulp Mills: Fabric expansion joints are used in paper and pulp mills to accommodate movements in ducting systems, such as those found in recovery boilers, digesters, and evaporators.

5. Steel and Metal Production:

   • Furnace and Kiln Systems: Fabric expansion joints are installed in furnace and kiln systems of steel mills and metal production facilities to accommodate movements caused by thermal expansion and contraction, as well as to isolate vibration and noise.
   • Exhaust and Emission Control Systems: Fabric expansion joints are used in exhaust and emission control systems of steel mills and metal processing plants to handle high temperatures and corrosive gases, providing flexibility and durability in harsh environments.

6. Aerospace and Defense:

   • Test Facilities: Fabric expansion joints are employed in test facilities for aerospace and defense applications to accommodate movements in ducting systems, such as those used for engine testing, environmental testing, and wind tunnels.

These are just a few examples of the diverse applications of fabric expansion joints across different industries. In each application, fabric expansion joints play a critical role in maintaining the integrity and functionality of piping systems while providing flexibility, durability, and resistance to harsh operating conditions.
