Duct is a piping system used for air transportation and distribution. There are two types of air ducts: composite air ducts and inorganic air ducts. Composite ducts are represented by Durkduct ducts. It can be classified by cross-sectional shape and material. The production of stainless steel air ducts involves applying sealant (such as neutral glass glue) to the seams of bite joints, rivet joints, flange flanges, and corners. Before applying sealant, the surface dust and oil stains should be cleaned. According to the cross-sectional shape, air ducts can be divided into various types such as circular ducts, rectangular ducts, flat circular ducts, etc. Among them, circular ducts have low resistance but large height dimensions, making them complex to manufacture. So the application is mainly based on rectangular ducts. According to material, air ducts can be divided into metal ducts, composite ducts, and polymer ducts.
