A, air supply, ventilation, such as the supply of fresh air and exhaust, this limitation is very limited, such as the workshop, production site air, because of the harmful gas demand outdoors, and the demand for outdoor air to indoor. At this time, the use of large flow and pressure of the air to keep the ventilation pipe, the spiral pipe is the most suitable, under the ordinary condition of the use of galvanized iron pipe, corrosion and special humid occasions to use stainless steel pipes.

b、 送涼風(fēng)。經(jīng)常見(jiàn)的是中心空調(diào)的管道，這種管道需求加保溫資料。螺旋風(fēng)管可內(nèi)貼保溫資料，表面看來(lái)美觀。

B, send cool wind. The most frequently seen is the central air-conditioning pipe, which needs additional insulation data. The spiral duct can be pasted with thermal insulation material and the surface looks beautiful.

c、 排油煙。飯鋪、酒樓、賓館的廚房均有很多油煙發(fā)生，需求排出，運(yùn)用圓形的風(fēng)管就是油煙囪。在這里，螺旋風(fēng)管該叫做油煙管。

C, exhaust fume. There are many cooking fumes in the kitchen, restaurant and hotel, and the demand is exhausted. The circular duct is the chimney. Here, the spiral wind pipe should be called the oil smoke tube.

d、 除塵。有些工場(chǎng)出產(chǎn)車(chē)間良多塵埃，需求專(zhuān)門(mén)的除塵安裝，個(gè)中風(fēng)流量較大的管道，可運(yùn)用螺旋風(fēng)管。

D, dust removal. Some workshops produce lots of dust and require special dust removal installation. A larger stroke pipeline can be used with a spiral air duct.

e、 散裝物料保送。有些工場(chǎng)的出產(chǎn)進(jìn)程中，需求保送松懈的顆粒，特殊是比重不大的如發(fā)泡塑料粒之類(lèi)的運(yùn)用螺旋風(fēng)管造價(jià)低、結(jié)果好。

E, bulk material delivery. In the production process of some factories, the need to keep loose particles, especially the small proportion, such as foam plastic particles, such as the use of spiral pipes, low cost, good results.
