Overview
Fabric Expansion Joints offer superior flexing capabilities compared to other solutions and can be made from a variety of special woven fabrics coated or laminated with selected elastomers or fluoropolymers. Fabric Expansion Joints are used to insulate, to avoid mechanical loads and to protect against abrasion. They offer advantages for the pipe work designer as they can absorb movements simultaneously in several directions. Furthermore, they have almost no reactive forces and require little space. Fabric Expansion Joints are easy to customise to suit existing operating conditions and are easy to transport and install in piping and ducting systems. In comparison to Metallic Expansion Joints, Fabric Expansion Joints offer almost unlimited flexibility, giving the pipe work designer more options.
Features
• Relative light weight
