The steel belt spiral duct machine adopts steel belts of different specifications and lengths, and can process ducts of corresponding size or any size. And according to the length required by the use, the high-speed synchronous automatic cutting system can be used for cutting. Tube die and plasma cutting function can be added additionally (steel strip plus pipe die, circular saw cutting and plasma cutting, one machine with four functions, to meet the different processing needs of customers.)

Steel belt spiral duct machine

　　 Spiral duct machine is used to produce spiral ducts, which are used in various military industries, and are also used in the manufacture of ventilation ducts and exhaust ducts in trains and subways in our lives. The high-quality spiral duct runs without big noise, does not leak water and air, and has good corrosion resistance. The spiral duct machine was originally developed by Switzerland, and my country has always relied on imports, but later on, my country developed the spiral duct machine by relying on the imported advanced technology.

　　 Spiral duct machine is a machine for producing spiral ducts. Spiral ducts, also known as spiral seam thin-walled ducts, were first used in military industries in 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 product has good matching, high degree of 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.
