It can be classified according to cross-sectional shape and material. Air duct production Stainless steel air duct production is to apply sealant (such as neutral glass glue) on the seams such as bite seams, rivet seams, and the four corners of flange flanging. Before applying sealant, the surface dust and oil should be removed. According to the cross-sectional shape, air duct can be divided into circular air duct, rectangular air duct, oblate air duct and other types.
