Description

Technical Field

[0001] The utility model belongs to the technical field of air ducts, and in particular relates to an air duct made of corrosion-resistant composite material. Background Art

[0002] Ducts are pipe systems used for air delivery and distribution. There are two types: composite ducts and inorganic ducts. Composite ducts can be classified by cross-sectional shape and material. Duct production Stainless steel duct production is to apply sealant (such as neutral glass glue) to the seams such as the bite seams, rivet seams, and the four corners of the flange. Before applying the sealant, the surface dust and oil should be removed. According to the cross-sectional shape, ducts can be divided into circular ducts, rectangular ducts, oblate ducts, etc. Among them, circular ducts have the smallest resistance but the largest height size, and are complex to make, so rectangular ducts are mainly used. According to the material, ducts can be divided into metal ducts, composite ducts, and polymer ducts.

[0003] For the convenience of transportation, composite air ducts are often transported to the place of use in multiple sections and then assembled on site, connected by flanges and welding. However, the port connections of the two sections of composite air ducts are easily damaged due to long-term use or impact, causing direct leaks that affect their use. Dust accumulated on the outer wall of the composite air duct will also corrode the outer wall of the duct to a certain extent, shortening its service life. Therefore, staff are required to frequently clean the dust in the duct and check the condition of the port connections, which is time-consuming and labor-intensive, and there is a risk when cleaning at high places.
