Fabric expansion joints can be used in several industries. They are used mostly for the transportation of cold air, hot air and gasses. The fabric expansion joint bellow is composed of several layers of fabric and foils (rubbers, PTFE, plastics, …). These are selected to suit the criteria of the application. Several shapes of the bellow (square, rectangular, round, …) are possible as well as a range of sizes.
These types of expansion joints are very dependent on the application. Therefore these types of expansion joints are always tailored to suit costumer-specific design
■ Excellent temperature range
■ Low spring rate
■ Short built in lengths
■ Very good vibration and noise absorption
■ Limited pressure resistivity
Fabrics are selected based on:
■ Chemical resistance
Fabric expansion joints are often used for the transportation of gasses and air. The gasses can require a very good chemical resistivity. If the appropriate fabric layers are selected it is possible to transport almost every gas.
