Fabric pipe expansion joints are often used in ducts which carry hot gases at low pressures. The major design parameters are the temperatures and flow rates of the gases and the amount and abrasiveness of solids suspended in the gases. Layers of different fabrics insulation can be combined to accommodate the temperatures and pressure in the system. The fabric belt may need to be replaced periodically.
SMART-SHIELD expansion joints consist of layers of material bonded, sewn or mechanically fastened together along the edges. Each layer of material is designed to function independently of the others.
Our expansion joints are recommended for temperature applications from 204°C to in excess of 1200°C. The material used as the outer layer of the composite expansion joint consists of a All weather proof fluoropolymer fiberglass product with a secondary corrosion barrier of cross-plied PTFE resulting in a superior chemical resistant product with ZERO porosity
