Q&A: Briefly describe the common connection methods for air ducts and their applicable ranges. Correct answer: The connections of metal ducts include biting, riveting, and welding. Bite joint: Suitable for thin steel plates, stainless steel plates, and aluminum plates of relatively low thickness. Riveting: Riveting is primarily used for the fixed connection between air ducts and angle steel flanges. Welding: Suitable for ducts with thicker plates or those that require high levels of tightness in their ventilation and air conditioning systems.
The connections of metal ducts are of three types: biting, riveting, and welding. Bite joint: Suitable for thin steel plates, stainless steel plates, and aluminum plates of relatively low thickness. Riveting: Riveting is primarily used for the fixed connection between air ducts and angle steel flanges. Welding: Suitable for ducts with thicker plates or those that require high levels of tightness in their ventilation and air conditioning systems.

Pipes can be connected in three main ways: threaded connections, welding, and flanges. Threaded connections are suitable for low pressures and small pipe diameters, generally below 0.1 MPa and DN100. Welding and flanges are suitable for all pipe diameters and pressures; flanges can be removed, which facilitates maintenance of equipment or pipelines, but they offer less safety compared to welding

The methods for connecting air ducts include: 1. Clamp-type connection: This is mainly used for connecting circular steel plate air ducts and spiral air ducts; first, bulges are formed at both ends of each duct segment, with one end being reduced to a smaller opening. During installation, insert the smaller opening into the larger one in the direction of airflow; then use steel clamps to tightly secure the two ends together, and finally fix them by passing bolts through the rings and tightening them. 2. Plug-in connection: mainly used for connecting rectangular or circular air ducts. First, create the connecting pipe, then insert it into the air ducts on both sides, and finally secure it tightly with rivets. 3. Plug connection: mainly used for connecting rectangular air ducts. Insert cuttings of different forms at both ends of the duct, then compact them. 4. Hose connection: Mainly used to connect air ducts with components such as radiators and side air outlets of static pressure boxes. During installation, the ends of the hose are placed over the connected pipes, and then the hose is tightened using a particularly soft clamp.
