Anti-Seismic flexible ventilation pipelines are specially designed for the ventilation and smoke exhaust systems of buildings. They are typically made of flexible materials with fire-resistant properties to meet the basic material requirements of relevant fire protection regulations. This product is intended to provide necessary displacement compensation for the duct system during earthquakes or structural deformations, thereby maintaining the smoothness of the ventilation and smoke exhaust paths as much as possible. Its structural form is convenient for connection with existing metal ducts through flanges and other methods, which helps to achieve a simple and efficient installation process and is suitable for various building spaces with continuous operation requirements for air circulation and fire safety.
