Below, we will explain the advantages of spiral duct machines in the ventilation industry
Currently, most products are widely used in shipbuilding, ventilation, purification, bridge dust removal, airports, tunnels and other construction industries. After years of research and the introduction of advanced Swiss technology, the company's developed spiral duct machine has reached a domestically advanced level. Since its launch, it has shown excellent performance and low operating costs, and its application in ventilation and air conditioning systems is constantly expanding. The coil diameter is 85-1400 mm ，and the processed plate thickness is 0.4-1.2 mm 。
(1) Dust removal system: Spiral duct machines can be used for the collection and transportation of dust removal devices. (2) Oil smoke exhaust system: The kitchens of hotels and restaurants produce a large amount of oil smoke that needs to be discharged. Spiral ducts are suitable, strong, economical, and practical. (3) Air conditioning system: Insulation materials can be attached to spiral ducts, resulting in a beautiful appearance. (4) Bulk material transportation: Pneumatic conveying system, some finer and looser material particles can be transported through spiral ducts, which is cost-effective and efficient. (5) Ventilation system: Supplying fresh air and exhausting air, harmful gases are discharged outdoors, and outdoor fresh air is sent indoors. Generally speaking, the flow rate of the ventilation system is very large, requiring the use of air ducts with low resistance to save—the manufacturing and operating costs of spiral ducts. Galvanized iron pipes are generally used, and stainless steel pipes are used in corrosive and particularly humid places.
Characteristics of spiral duct machines:
1. Steel properties:
With the same length, the number of flange connections is less, overall performance is superior to rectangular ducts, greatly improving the ventilation quality of the system.
Under the same plate thickness and the same pipe diameter, the spiral duct has high strength.
Under the same cross-section, the structural tension of a circular duct is more reasonable than that of a rectangular duct, greatly improving the rigidity of the duct and significantly reducing vibration noise.
The air duct has a circular appearance, which is aesthetically pleasing.
2. Speed:
High efficiency, suitable for large-scale projects with short construction periods.
No procedures need to be processed at the construction site, reducing the number of on-site operators and management procedures.
Mechanized production, fast.
Compared with rectangular ducts, the supporting non-standard pipe fittings have a high degree of standardization, are easy to install, and the probability of errors is greatly reduced.
Small diameter spiral ducts can be quickly lifted with a single lifting point.
The number of connecting flanges is small, reducing the workload of installation and connection 50% .
3. Economy:
During construction, the installation efficiency is twice that of rectangular ducts.
Under the same conditions, low-speed air supply and exhaust can be changed to high-speed air supply and exhaust, and the system design can reduce the total amount of air ducts, saving both cost and space.
Under the same conditions, the results of all auxiliary materials are simple, the quantity is small, and the installation cost of auxiliary materials is reduced. 30%。
According to the specifications, under the same pipe diameter, the plate thickness will be reduced by 10-15% 。
The above is the explanation of the advantages of spiral duct machines in the ventilation industry. Thank you for watching, and see you next time.
