(1)送風
(1) Air supply
包括通氣，如送鮮風和排氣，這個范圍很廣，如工廠車間，生產場地空氣，由于有害氣體產生需要排出室外，又需要把室外空氣輸送室內。這時就要使用流量大而壓力小的空氣輸送管道，螺旋風管就適用，一般情況下使用鍍鋅鐵管，有腐蝕性及特別潮濕場所使用不銹鋼管。
It includes ventilation, such as fresh air supply and exhaust. This range is very wide, such as the air in factories, workshops and production sites. Due to the generation of harmful gases, it needs to be discharged outdoors, and the outdoor air needs to be transported indoors. At this time, the air transmission pipeline with large flow and low pressure shall be used, and the spiral air duct is applicable. Generally, galvanized iron pipe shall be used, and stainless steel pipe shall be used in corrosive and particularly humid places.
(2) 送冷風
(2) Cold air supply
送冷風。常見的是空調的管道，這種管道需要加保溫材料。螺旋風管可內貼保溫材料，外表看來美觀。
Send cold air. The common is the air-conditioning pipeline, which needs to add thermal insulation materials. Spiral air duct can be pasted with thermal insulation material, which looks beautiful.
(3) 排油煙
(3) Oil fume exhaust
飯店、酒樓、賓館的廚房均有大量油煙產生，需要排出，使用圓形的風管就是油煙囪。在這里，螺旋風管該叫做油煙管。
The kitchens of hotels, restaurants and hotels produce a large amount of oil fume and need to be discharged. The use of circular air duct is oil chimney. Here, spiral air duct should be called oil fume pipe.
(4) 除塵
(4) Dust removal
有些工廠生產車間很多塵埃，需要專門的除塵裝置，其中風流量較大的管道，可使用螺旋風管。
There is a lot of dust in the production workshops of some factories, which requires special dust removal devices. Spiral air ducts can be used for pipes with large air flow.
(5) 散裝物料輸送
(5) Bulk material transportation
有些工廠的生產過程中，需要輸送松散的顆粒，特別是比重不大的如發泡塑料粒之類的使用螺旋風管造價低、效果好。
In the production process of some factories, loose particles need to be transported, especially those with small proportion, such as foamed plastic particles. The spiral air duct has low cost and good effect.
