Spiral Duct Use
- May 31, 2018 -

The spiral air duct is a thin-walled tube made of metal strip coils with a spiral seam. It is round, non-welded, airtight and watertight. It is mostly used for air supply and bulk material transportation, instead of the traditional white iron pipe. Is a kind of duct, full mechanism, straight pipe without manual knocking. Its main uses are as follows:

The supply of spiral air ducts, including ventilation, such as fresh air and exhaust air, covers a wide range. For example, factory floor, production site air, and the need to vent outdoor air due to the generation of harmful gases require outdoor air to be delivered indoors. At this time, it is necessary to use a large-pressure and low-pressure air transmission pipe. The spiral air pipe is most suitable. In general, galvanized iron pipes are used, and stainless steel pipes are used in corrosive and particularly humid places.

Spiral ducts send cold air. The most common is the central air-conditioning pipeline, which requires the addition of insulation material. The spiral air duct can be inlaid with thermal insulation material, which looks beautiful.

Spiral duct smoke. The kitchens of restaurants, restaurants, steel pipes, and hotels all generate a lot of fumes and need to be discharged. The use of circular ducts is an oil chimney. Here, the spiral duct is called a soot tube.

Spiral duct dust removal. Some factories produce a lot of dust in the workshop and need specialized dust removal devices. The ducts with large air flow volume can use spiral air ducts.

Helical ducts for bulk material handling. In some factories, loose particles must be transported during the production process. In particular, spiral ducts with low specific gravity, such as foamed plastic pellets, have low cost and good results.
