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、送风：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，螺旋风管就很适用，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。

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、散装物料输送：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。

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、除尘：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。

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.

螺旋通风管道受到了人们的喜爱，而且较为难得的是在使用过程中，任何一处有损坏，均可随意进行切割粘接修补，维修相当方便。

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.
