Spiral tube coil is made of spiral seam of thin walled tube, metal belt round, no welding, no leakage, no Water Leakage, used for air and bulk transport, instead of the traditional tin pipe (i.e. manual seam pipe). It is a kind of wind pipe, the whole mechanism, the straight pipe needs no hand beating. Its main uses are as follows:

1. 排油煙，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。

1 exhaust, hotel, restaurant and hotel kitchens have a lot of fume, need to discharge, using circular duct is smoke chimney. Here, the spiral pipe should be called the soot pipe.

2.送風，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。

2. air supply, including ventilation, such as fresh air supply and exhaust, this range is very wide, such as factories, workshops, production sites, air, due to the production of harmful gases, need to be discharged outside, and the need to transport outdoor air to the interior.

3. 散裝物料輸送。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。

3. bulk material handling. Some factories in the production process, the need to transport loose particles, especially small proportion, such as foam plastic particles such as the use of spiral duct, low cost, good effect.
