螺旋风管主要用途
Main uses of spiral duct
(1) 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，螺旋风管就最适用，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。
(1) Air supply, including ventilation, such as fresh air supply and exhaust, has a wide range, 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 use of large flow and low pressure air pipeline, spiral air duct is the most suitable, generally use galvanized iron pipe, corrosive and particularly humid places use stainless steel pipe.
(2) 送冷风。最常见的是中央空调的管道，这种管道需要加保温材料。螺旋风管可内贴保温材料，外表看来美观。
(2) Send cold air. The most common is the central air conditioning pipe, which needs to be added with insulation material. Spiral air duct can be pasted with thermal insulation material, which looks beautiful.
(3) 排油烟。饭店、酒楼、宾馆的厨房均有大量油烟产生，需要排出，使用圆形的风管就是油烟囱。在这里，螺旋风管该叫做油烟管。
(3) Exhaust lampblack. Restaurants, restaurants, hotel kitchens have a large amount of cooking fume, need to be discharged, the use of circular duct is the chimney. Here, the spiral duct should be called a lampblack.
(4) 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。
(4) Dust removal. Some factory workshops have a lot of dust, so special dust removal device is needed. Spiral duct can be used for pipes with large air flow.
(5) 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。
(5) Bulk material transportation. In the production process of some factories, it is necessary to transport loose particles, especially for those with small specific gravity such as foamed plastic particles. The cost of spiral duct is low and the effect is good.
