Spiral ventilation duct

Characteristics of Spiral Duct

Economy:

A： According to national regulations, for the same pipe diameter, the plate thickness can be reduced by 10-15%. (Main material cost reduced by 10-15%)

B： Under the same conditions, the results of fully loaded auxiliary materials (such as hanging keys) are simple, the quantity is small, and the installation cost of auxiliary materials is reduced by 30%
C: The lifting efficiency during construction is twice as high as that of rectangular air ducts.
D： Under the same conditions, the low-speed air supply and exhaust of the air duct can be changed to high-speed air supply and exhaust. The system design can reduce the total amount of air ducts, which is not only economical but also saves space
possibility:

A： Under the same thickness and diameter, spiral ducts have high strength.

B： The exterior of the air duct is circular and aesthetically pleasing.
C： Under the same cross-section, circular ducts have a reasonable tension compared to rectangular ducts, significantly improving duct rigidity and significantly reducing vibration noise.
D： Under the same length, the number of flange connections is less, and the bee performance is better than that of rectangular ducts, greatly improving the ventilation quality of the system.
Shortcut:

A： Efficient construction, used for large-scale projects with short construction periods.

B： Mechanized production, fast and efficient.
C： The number of connecting flanges is small, reducing the workload of lifting and connecting by about 50%.
D： Small diameter spiral air duct single lifting point, fast and efficient lifting.
E： No need for on-site processing procedures, reducing the number of on-site workers and management procedures.
F： Compared with rectangular ducts, the standardization level of supporting irregular fittings is high, the lifting is simple, and the probability of errors is greatly reduced.
