Fan soft connection is a bellows expansion joint used for transporting high-temperature metal particles, involving an improvement of a vertical bellows expansion joint used for transporting high-temperature metal particles

Fan soft connection is a type of bellows expansion joint used for transporting high-temperature metal particles, which involves an improvement of a vertical bellows expansion joint used for transporting high-temperature metal particles. The expansion joint includes an upper flange, a lower flange, and a serpentine corrugated pipe, characterized in that a steel inner lining sleeve is also provided inside the serpentine corrugated pipe. The temperature resistance of high temperature resistant telescopic air ducts and high temperature resistant flexible connections is as follows: 1. The outer layer is made of double-layer silicone glass fiber cloth, which can seal without air leakage and withstand temperatures from -80 ° C to 350 ° C. 2. The inner layer is made of a layer of vermiculite glass fiber cloth or high silica glass fiber cloth, which can withstand high temperatures from 900 ° C to 1200 ° C for a long time
