Characteristics of Oval Spiral Duct in Ventilation Industry

At present, most of the products are also widely used in shipbuilding, ventilation, purification, bridge dust removal, airport, tunnel, and other construction industries. The oval spiral duct itself has excellent performance and low operation cost. Its application in ventilation and air conditioning systems has been promoted continuously. The diameter of the volume tube is 85-1400mm, and the thickness of the processing plate is 0.4-1.2m. What are the characteristics of the oval spiral duct?


Ⅰ. The advantages of an oval spiral duct over a circular duct


1. With the same length, the number of flange connections is less; the sealing performance is better than the rectangular duct so that the ventilation quality of the system is greatly improved.


2. With the same thickness and the same pipe diameter, the oval spiral duct has high strength.


3. With the same section, the structural tension of the circular duct is reasonable than that of the rectangular duct, which greatly improves the rigidity of the duct and significantly reduces the chatter noise.


4. The appearance is round and beautiful.


Ⅱ. The convenience of the oval spiral duct


1. High-efficiency construction, which is suitable for large projects with a short construction period.


2. No construction site processing process is required, which can reduce the site operation personnel and management procedures.


3. Mechanized production, fast and efficient


4. Compared with the rectangular duct, the matching special-shaped pipe fittings have a high degree of standardization, and the lifting is simple. The probability of error is greatly reduced.


5. The small diameter oval spiral duct has a single lifting point. Lifting is fast and efficient.


6. The number of connection flanges is less, and the lifting connection workload is reduced by about 50%.


Ⅲ. The oval spiral duct has low cost and is more affordable


1. The lifting efficiency during construction is doubled that of rectangular duct.


2. Under the same conditions, the low-speed exhaust of the operating air duct can be transformed into high-speed air exhaust. The system design can reduce the total amount of oval spiral duct, which is not only economical but also saves space.


3. Under the same conditions, the installation of auxiliary materials is simple; the quantity is small, and the cost of installing auxiliary materials is reduced by 30%.


4. According to the specification, the plate thickness is reduced by 10-15% for the same pipe diameter
