Single flat seam: It is used for the splicing seam of the board and the longitudinal closing seam of the round air duct, as well as the seam of the product that does not require high tightness.Single vertical bite: used for the circular joints at the ends of round air ducts, such as circular elbows and circular back and forth bends between the joints of each pipe segment.Corner bite: used for longitudinal seams of rectangular air ducts and fittings, corner seams of rectangular pipes and tees.Combined corner bite: also called corner bite, the bite seam is on the corner of the rectangular pipe, and the purpose is the same as the corner bite. It is more suitable for the corner seam connection of curved rectangular pipes.Snap Seam: Corner closure seam for rectangular duct and fittings. One side of the plate is processed into a socket with a convex buckle, and the other side of the plate is processed into a socket with a barb shape on the folded edge. When installing, insert the socket into the socket to form a seam: this kind of bite It is characterized by tight bite and reliable operation.At present, most of the bites are machined.

There are three types of air ducts: bite, riveting and welding, among which the bite connection is the most common application. (The bite connection folds the two plate edges that need to be combined into various hook shapes that can bite each other. It is suitable for thin steel plates with a thickness of ≤1.2mm, stainless steel plates with a thickness of ≤1.0mm and aluminum plates with a thickness of ≤1.2mm.

1. Air duct materials can be divided into metal and non-metal; Metal air ducts are divided into steel air ducts (galvanized steel air ducts), aluminum air ducts and stainless steel air ducts wait; 2. Metal air ducts are widely used at present, and can be used as conveying air (air supply and exhaust), conveying smoke Gas, boiler flue and pneumatic conveying, etc.; 3. Galvanized steel air ducts are often used in comfort air conditioning systems; 4. Aluminum plate air ducts and stainless steel air ducts are mostly used in technological air-conditioning systems (purifying air-conditioning) and anti-static places with higher requirements. 5. Non-metallic air ducts are divided into phenolic aluminum foil composite air ducts, polyurethane composite air ducts, and glass fiber composite air ducts. Pipe, hydraulic inorganic glass steel air duct, magnesium oxychloride cement air duct, rigid polyvinyl chloride air duct, etc.
