（1）送风

(1) air supply

包括通气，如送鲜风和排气，这个范围很广，如工厂车间，生产场地空气，由于有害气体产生需要排出室外，又需要把室外空气输送至室内。这时就要使用流量大而压力小的空气输送管道，螺旋风管就最适用，一般情况下使用镀锌铁管，有腐蚀性及特别潮湿场所使用不锈钢管。

Including ventilation, such as fresh air and exhaust, this range is very wide, such as factory workshop, production site air, because of the harmful gas production needs to discharge outside, and the need to transport outdoor air to the room. At this time, the use of large flow and pressure small air transportation pipeline, the spiral pipe is the most suitable, in general, the use of galvanized iron pipe, corrosive and special wet places to use stainless steel pipe.

(2) 送冷风

(2) send a cold wind

送冷风。最常见的是中央空调的管道，这种管道需要加保温材料。螺旋风管可内贴保温材料，外表看来美观。

Send a cold wind. The most common is the central air conditioning pipeline, this piping needs to add the heat preservation material. The spiral duct can be attached with thermal insulation material and looks beautiful.

(3) 排油烟

(3) exhaust fume

饭店、酒楼、宾馆的厨房均有大量油烟产生，需要排出，使用圆形的风管就是油烟囱。在这里，螺旋风管该叫做油烟管。

There are a lot of fumes in restaurants, restaurants and hotel kitchens, which need to be discharged. The circular duct is the chimney. Here, the spiral wind pipe should be called the oil smoke tube.

(4) 除尘

(4) dust removal

有些工厂生产车间很多尘埃，需要专门的除尘装置，其中风流量较大的管道，可使用螺旋风管。

Some factories have a lot of dust in the workshop, and special dust removal devices are needed.

(5) 散装物料输送

(5) bulk material transportation

有些工厂的生产过程中，需要输送松散的颗粒，特别是比重不大的如发泡塑料粒之类的使用螺旋风管造价低、效果好。

In the production process of some factories, it is necessary to transport loose particles, especially the small proportion, such as foam plastic particles, such as the use of spiral pipes, low cost, good effect.
