The main uses and characteristics of spiral ducts produced by spiral duct machines

At present, the spiral ducts produced by the spiral duct machine have been widely used in coal mines, shipbuilding, ventilation, purification, airports, tunnels, building decoration and other industries. In recent years, the spiral duct machine developed through research and introduction of advanced Swiss technology has reached the domestic advanced level, with a coil diameter of 80-1500mm and a processing plate thickness of 0.4-1.2mm. 

The spiral ducts produced by the spiral duct machine are mainly used for: 

(1) Ventilation system: providing fresh air and exhaust, discharging harmful gases to the outside, and delivering fresh air from the outside to the room. The flow rate of the ventilation system is large. Therefore, in order to save costs and operating costs, it is necessary to use low-resistance air delivery pipes - spiral cyclone ducts produced by spiral fans are more suitable. Galvanized strip steel is used as raw material, and stainless steel can also be used in corrosive and particularly humid places.

(2) Air conditioning system: central air conditioning, cold storage, etc., spiral ducts can be covered with insulation materials inside, and the appearance is beautiful. 

(3) Fume exhaust system: canteens, restaurants, and hotel kitchens produce a lot of fume, which needs to be exhausted. Spiral ducts are more suitable to replace traditional hand-made ducts. Spiral ducts have good strength, economy and practicality. 

(4) Dust removal bulk material conveying system: flour mills, flower bouquet factories, feed mills, etc., collection and transportation of dust removal equipment. In the pneumatic conveying system, some fine and loose material particles can be transported through spiral ducts, which is low cost and good effect. 

Spiral ducts produced by spiral fans: Economic type:

1: According to national standards, under the same pipe diameter, the main material cost is reduced by 15-20%, and the equivalent installation auxiliary materials (hanging keys, etc.) are simple to install, the quantity is small, and the cost is reduced by 30%. During construction, the hoisting efficiency is twice that of other ducts. 

2: Under the same conditions, the low-speed delivery and exhaust of the air duct is changed to high-speed delivery and exhaust. The system design can reduce the total amount of the air duct, which is both economical and space-saving. 

3: Under the same plate thickness and the same pipe diameter, the spiral duct has high strength and beautiful appearance. Under the same cross-section, the spiral duct is more reasonable than other duct structures and significantly reduces vibration noise. With fewer flange connections for the same length, the sealing performance is superior to other ductwork, ensuring high-quality system ventilation.

Spiral ducting produced by spiral fans: Speed:

1. Efficient construction. For short, urgent projects, mechanized production is fast and efficient.

2. Fewer connecting flanges reduces the installation workload by approximately 50%. Small-diameter spiral ducts have a single hanging point, making installation quick and efficient.

3. No on-site machining is required, reducing on-site operations and management. The matching custom-shaped pipe fittings can be assembled on-site, simplifying installation.

Currently, the country is vigorously promoting energy conservation across all industries. This product aligns with the trend of the times and fills a domestic gap. It is highly worthy of widespread promotion and adoption.
