The main uses of spiral air duct are as follows:

（1）送風，包括通風，如新風和排風，這個范圍很廣，如工廠車間、生產現場的空氣，由于有害氣體需要排到室外，也需要將室外空氣輸送到室內。這時我們要用大流量小壓力的空氣輸送管，螺旋式空氣輸送管比較合適，一般用鍍鋅鐵管，尤其是有腐蝕性和潮濕的地方用不銹鋼河北螺旋風管。

(1) Air supply, including ventilation, such as fresh air and exhaust, covers a wide range, such as the air in factory workshops and production sites. Because harmful gases need to be discharged outdoors, it is also necessary to transport outdoor air indoors. At this time, we need to use air conveying pipes with large flow and low pressure. Spiral air conveying pipes are more suitable. Galvanized iron pipes are generally used, especially corrosive and humid Local stainless steel spiral air duct.

（2）送冷空氣。比較常見的是中yang空調管道，這種管道需要添加保溫材料。螺旋風管可貼保溫材料，外形美觀。

(2) Supply cold air. The more common is the medium Yang air conditioning pipe, which needs to add thermal insulation material. The spiral air duct can be pasted with thermal insulation material, with beautiful appearance.

（3）餐廳、餐廳、酒店的廚房有很多油煙，需要排放，使用環形風管就是油煙筒。在這里，螺旋管應稱為油煙管。

(3) There is a lot of oil fume in the kitchen of restaurants, restaurants and hotels, which needs to be discharged. The circular air duct is the oil fume drum. Here, the spiral pipe should be called the oil fume pipe.

（4）除塵。有些工廠的生產車間粉塵較多，需要專門的除塵裝置。對于風量大的管道，可采用螺旋風管。

(4) Dust removal. There is a lot of dust in the production workshops of some factories, so special dust removal devices are required. Spiral air ducts can be used for pipes with large air volume.

（5）散裝物料搬運。有些工廠在生產過程中，松散的顆粒需要運輸，尤其是比例小的，如泡沫塑料顆粒，采用螺旋風管，成本低，效果好。

(5) bulk material handling. In some factories, loose particles need to be transported during production. Especially small proportion, such as foam plastic particles, adopts spiral air pipes, which has low cost and good effect.

螺旋風管的九個優點是：

The nine advantages of spiral duct are:

1）兼容性好，標準化程度高；

1) Good compatibility and high degree of standardization;

2）強烈的緊張；

2) Intense tension;

3）通風損失小；

3) Small ventilation loss;

4）工廠檢查方便；

4) Convenient factory inspection;

5）反平衡外壓（負壓）程序；

5) Counter balance external pressure (negative pressure) procedure;

6）材料保存；

6) Material preservation;

7）安裝成本低；

7) Low installation cost;

8）整體安裝布局美觀；

8) The overall installation layout is beautiful;

9）方便日常保養和清潔。

9) Convenient for daily maintenance and cleaning.
