Fabric Expansion Joint These types of expansion joint are used in low pressure systems and these are a cost-effective substitute for such systems. These can be made in large diameters . Moreover, bellows can be made of various shapes viz. polygon, rectangular, etc. Fabric expansion joint is a multi-layer design. Temperature and corrosion resistant insulating fabrics for temperature decrease Gas impermeable films, foils or composites of materials as Teflon, Silicone, Hypalon, Inconel or aluminium UV resistant and water-resistant materials for reasons of weather protection. Support layers such as glass or polyester fabric and the like for pressure absorption; Mechanically stable layers such as wire mesh and silicone film as abrasion protection.
