Advantages of spiral air duct in ventilation industry


At present most of the products are widely used in shipbuilding, ventilation, purification, Bridges, dust removal, airport, tunnel construction, jiang yin the company after many years of study for advanced technology development of Switzerland spiral wind mill has reached domestic advanced level, since the market itself has excellent performance and low cost, application in the ventilation and air conditioning system continuously promoted, volumes of 85-1400 mm in diameter, the processing of thickness 0.4 1.2 mm, main use is as follows:

Dust removal system: the collection and transportation of dust removal device can use spiral air duct.

Lampblack system: the kitchen of the hotel, restaurant and hotel produces a large amount of lampblack, which needs to be discharged. spiral air duct is suitable, with good strength and economy.

Air conditioning system: spiral air duct can be lined with thermal insulation material, with beautiful appearance.

Bulk material conveying: pneumatic conveying system, some of the finer and loose material particles, can be transported by spiral air duct, with low cost and good effect.

Ventilation system: supply fresh air and exhaust, discharge harmful gas outdoors and bring outdoor fresh air indoors. In general, ventilation systems have a high flow rate and require the use of less resistance air ducts to save costs and operating expenses – spiral air duct are most suitable. Generally use galvanized iron pipes, stainless steel pipes in corrosive and particularly humid places.

Features of spiral air duct:


Under the same length, the number of flange connections is small, and the performance of bee is better than that of rectangular air duct, which greatly improves the ventilation quality of the system.

With the same sample thickness and the same pipe diameter, the spiral air pipe has high strength.

Under the same section, the tension of the circular duct is reasonable compared with the rectangular duct, which greatly improves the rigidity of the duct and significantly reduces the chatter noise.

Air duct is round in appearance and beautiful in appearance.


High efficiency construction, used in large projects with short construction period

There is no need for on-site processing, and on-site operation personnel and management procedures are reduced.

Mechanized production, fast and efficient

Compared with rectangular duct, the standard degree of supporting special-shaped pipe is high, the hoisting is simple and the error rate is greatly reduced.

Single lifting point of spiral air pipe with small pipe diameter, rapid and efficient lifting

The number of connection flanges is small, and the hoisting connection workload is reduced by about 50%.


Hoisting efficiency is twice as high as that of rectangular air duct during construction.

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

Under the same conditions, full auxiliary materials have simple results and less quantity, and the installation cost of auxiliary materials is reduced by 30%

According to national regulations, the same pipe diameter and plate thickness are reduced by 10-15%.
