Spiral duct has a wide range of applications. Air supply and return pipe of purification system, industrial air supply and exhaust ventilation pipe, air suction and exhaust pipe of environmental protection system, mine gas drainage pipe, mine adhesive cloth air duct, etc.

螺旋风管常用的4种加固方法，风管内支撑加固的排列应整齐、间距应均匀对称，应在支持件两端的风管受力（压）面处设置专用垫圈。

For the four commonly used reinforcement methods of spiral air duct, the support reinforcement in the air duct shall be arranged neatly, the spacing shall be uniform and symmetrical, and special gaskets shall be set at the stress (pressure) surface of the air duct at both ends of the support.

1、框架加固法：即采用轻钢龙骨加固。

1. Frame reinforcement method: light steel keel reinforcement is adopted.

2、抱合加固法：即采用轻钢龙骨加固，使用在拉杆加固和框架加固无法应用的某些特殊管道上，如900弯管、三通管、闷头管等。

2. Embracing reinforcement method: light steel keel reinforcement is adopted, which is used on some special pipes that cannot be used for tie rod reinforcement and frame reinforcement, such as 900 elbow, tee pipe, bulkhead pipe, etc.

3、防下垂加固法：它用于特殊管道的加固，如变经管道加固和迂回管道加固。

3. Anti sagging reinforcement method: it is used for the reinforcement of special pipelines, such as variable pipeline reinforcement and circuitous pipeline reinforcement.

4、拉杆加固法：它是采用钢彩、套管加固，通常使用在500Pa以下的正压加固。

4. Tie rod reinforcement method: it adopts steel color and casing reinforcement, and usually uses positive pressure reinforcement below 500pa.

这是按其用途定下的名称，但它又可用于其它地方，甚用来排水，排液体或作容器，这就不能叫它风管。按构造来命名，应管它叫螺旋咬缝薄壁管，由于主要用金属做的又管它叫螺旋咬缝金属管。如果按材料归类命名，大概可有这几个名：镀锌（铁）螺旋管、不锈钢螺旋管、铝螺旋管，或为了区别于现有不锈钢管，可管它叫超薄不锈钢管，因它可用0.3毫米甚更薄的不锈钢带卷制而成。

This is the name set according to its purpose, but it can be used in other places, even for drainage, liquid discharge or container, so it can't be called air duct. Named according to the structure, it should be called spiral seamed thin-walled pipe. Because it is mainly made of metal, it is also called spiral seamed metal pipe. If the material is classified and named, there may be several names: galvanized (iron) spiral pipe, stainless steel spiral pipe, aluminum spiral pipe, or in order to distinguish it from the existing stainless steel pipe, it can be called ultra-thin stainless steel pipe, because it can be rolled with 0.3mm or even thinner stainless steel strip.
