The spiral duct machine is a machine for producing spiral ducts. Spiral ducts, also known as spiral seam thin-walled ducts, were first used in the military industry of Western countries, such as warships, ship platoon (sending) air systems, and later in civilian facilities such as trains, subways, and mines. According to statistics, the use of spiral ducts in office buildings, shopping malls, and subways has reached 95.6%, and the use of spiral ducts in central air-conditioning in civil residences has also reached 72.5%.

　　 The production of spiral wind products has good compatibility and high standardization; strong airtightness; low ventilation loss; low ventilation noise, and round pipes are better than square pipes. Convenient factory inspection; anti-balanced external pressure (negative pressure) program; material saving; convenient installation, few connection points, small installation space and low installation cost. The overall layout of the installation is beautiful and the grade is high. It is convenient for daily maintenance and cleaning. The section has a small wet circumference, low resistance along the way, and less energy loss. Fully mechanical processing, no secondary processing is required for one-time molding. Using high-speed flying cutting machine, high precision of pipe diameter. It adopts four methods: reducing diameter socket, casing interconnection, flange interconnection, and strap interconnection, making the installation more convenient. The external insulation quality of the pipe is better than that of a rectangular duct.

The spiral duct machine must use the corresponding size pipe mold for each spiral duct with a pipe diameter. The pipe mold used is a steel mold, which is stronger, more durable and stable than the aluminum casting model. It adopts a high-speed circular saw automatic cutting system or rolling Shear cutting.
