(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室内。这时就要使用流量大而压力小的空气输送91视频成人网站，螺旋风管就适用，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。
It includes ventilation, such as fresh air supply and exhaust. This range is very wide, such as the air in factories, workshops and production sites. 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 shall be used, and the spiral air duct is applicable. Generally, galvanized iron pipe shall be used, and stainless steel pipe shall be used in corrosive and particularly humid places.
(2) 送冷风
(2) Cold air supply
送冷风。常见的是空调的91视频成人网站，这种91视频成人网站需要加保温材料。螺旋风管可内贴保温材料，外表看来美观。

There is a lot of dust in the production workshops of some factories, which requires special dust removal devices. Spiral air ducts can be used for pipes with large air flow.
(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, loose particles need to be transported, especially those with small proportion, such as foamed plastic particles. The spiral air duct has low cost and good effect.
