Fabric expansion joints, also called fabric compensators, are widely used in many projects because of their good comprehensive properties. Their uses lie mainly in dust media and gaseous media (air, exhaust gases). They work at temperatures that can reach 1000 – 1200 ° C and low pressures (0.1MPa). Fabric expansion joints are generally speaking elastic components that are suitable for absorbing pipeline expansions and vibrations or for compensating the installation of plant components. The design is decisively determined by the medium, pressure, temperature, size, and direction of the expansion to be absorbed. They can compensate for lengthy, crosswise, and devious movements. They are used in power plants, drainage and gas drying installations chimneys, desulphurization, chemical plants, refineries, and (steel) mills. When selecting fabric expansion joints, the flow speed of the medium is of great importance, which determines the selection of the appropriate fabric and the use of additional covers to protect the soft parts of the expansion joint. Fabric expansion joints are made of multiple layers of materials silicate, glass, aramid, or ceramic fabrics, which are selected depending on the temperature at which it will work compensator and depending on the medium with which it will come into contact.
