Flanged air duct

Duct is a pipeline used for air transportation and distributionsystemThere are two types of air ducts: composite air ducts and inorganic air ducts. Composite air ductDurkductRepresented by air 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 removed. 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 the lowest resistance but the highest height dimension, 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
