Non-metallic Expansion Joints

The elastic elements that make up the working body of non-metallic expansion joints are non-metallic materials,usually fiber fabrics,so they are also called fabric expansion joints (expansion joints,expansion joints).There is also rubber material, which can replace fiber fabric in various working conditions except when it cannot meet the service conditions at ultra-high temperature (above 400 °C).Non-metallic expansion joints can compensate axial and angular directions,has the characteristics of no thrust,simplified support design,corrosion resistance,high temperature resistance,noise reduction and shock absorption,etc.,especially suitable for hot air pipes and smoke pipes.
