Spiral air duct occupies a high proportion in many ventilation ducts. Spiral air duct is widely used. What are the uses of this kind of ventilation duct? Jiangsu ventilation pipe manufacturer comes to tell you:

A、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至室內。這時就要使用流量大而壓力小的空氣輸送管道，螺旋風管就很適用，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。

A. Air supply: it includes ventilation, such as fresh air supply and exhaust. This range is very wide, such as the air in the factory workshop and production site. 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 should be used, and the spiral air duct is very suitable. Generally, galvanized iron pipe is used, and stainless steel pipe is used in corrosive and particularly humid places.

B、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。

B. Bulk material transportation: in the production process of some factories, loose particles need to be transported, especially those with small specific gravity, such as foamed plastic particles. The use of spiral air duct has low cost and good effect.

C、除塵：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。

C. Dust removal: there is a lot of dust in the production workshops of some factories, and special dust removal devices are required. Spiral air ducts can be used for pipes with large air flow.

螺旋通風管道受到了人們的喜愛，而且較為難得的是在使用過程中，任何一處有損壞，均可隨意進行切割粘接修補，維修相當方便。

Spiral ventilation duct is loved by people, and what is more rare is that in the process of use, any damage can be cut, bonded and repaired at will, which is quite convenient for maintenance.
