GTE PRODUCT - FABRIC EXPANSION JOINT
Fabric expansion joints are extremely flexible 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 insuled, to avoid mechanical load and to protect against abrasion. They offer advantages for the pipe work designer as they absorb movements simultaneously in several direction, they have most no reactive forces and requires little space.
Fabric expansion joints are easy to customize to suit existing operating conditions and are easy to transport and install. In comparision to metallic expansion joints, fabric expansion joints offer almost unlimited flexibility and give numerous options for the pipe work designer.
Fabric expansion joints are installed in systems operating with low pressure and dry media
A fabric expansion joint is inserted into a gap in the ductwork where the movement will occur.
A fabric expansion joint has two main components: The fabric gas seal and The metal frame.
The fabric gas seal is a closed loop, like a belt, with its two edges clamped all around to the metal frames that are in turn connected to the end of the duct. As the ducting moves, the fabric belt deforms.
The fabric material must do this without tearing or leaking while sometimes being exposed to high temperatures and/or corrosive media.
In some instances, additional components such as insulation pillow, accumulation barriers or flow liners are utilized to help protect the fabric material.
