有些行业只是单纯的需要螺旋风管达到排风，转换空气的功能，但是有些行业如在机房、地下室、机械工程、采矿通风设备、消防排烟等恶劣工作环 境下的送风及排气、集除烟尘之用、耐高温及排风，要是以前的风管在使用上就不太可能实现这个效果，这种风管是具有很好的抗强酸及碱，良好的抗化学性，携带方便，耐油酸且阻燃；

Some industries simply need spiral air ducts to exhaust and convert air, but some industries, such as air supply and exhaust, smoke collection and dust removal, high temperature resistance and exhaust in harsh working environments such as machine rooms, basements, mechanical engineering, mining ventilation equipment, fire control and smoke exhaust, are unlikely to achieve this effect if the previous air ducts are used. This kind of air duct has good resistance to strong acid and alkali, Good chemical resistance, easy to carry, oleic acid resistance and flame retardant;

任意弯曲半径约等于外径，可排静电、螺旋丝接地，给安装时候带来很大的方便。空气一直都是我们人类所须呼吸的气体，要是你在一个密封的情况下要是没有进行空气的流通运输，那么就会出现窒息的可能性，所以现在很多人在空气不好的地方都安装通风管道。

The arbitrary bending radius is about equal to the outer diameter, which can discharge static electricity and screw wire grounding, bringing great convenience to installation. Air has always been the gas we humans need to breathe. If you do not carry out air circulation and transportation under a sealed condition, there will be the possibility of suffocation, so many people now install ventilation pipes in places with bad air.

漏光法检测是采用光线对小孔的强透视力，对系统螺旋风管严密程度进行定性检测的方法。其试验方法是在一定长度的螺旋风管上，在黑暗的环境下，在螺旋风管内用一个电压不高于36V、功率在100W以上的带保护罩的灯泡，从螺旋风管的一端缓缓移向另一端，试验时若在螺旋风管外能观察到光线，则说明螺旋风管有漏点，并对螺旋风管的漏风处进行修补。

The light leakage method is a qualitative method to detect the tightness of the spiral air duct of the system by using the strong penetration of light to the small hole. The test method is to use a bulb with a protective cover with a voltage of not more than 36V and a power of more than 100W to move slowly from one end of the spiral air duct to the other end on a certain length of spiral air duct in a dark environment. If light can be observed outside the spiral air duct during the test, it indicates that there is a leak point in the spiral air duct, and repair the leak point of the spiral air duct.

系统螺旋风管的漏光法检测采用分段检测、汇总分析的方法，被测系统的螺旋风管不允许有多处条缝形的明显漏光，低压系统螺旋风管每10米接缝，漏光点不超过2处，100米接缝平均不大于16处;中压系统螺旋风管每10接缝，漏光点不超过1处，100米接缝平均不大于8处为合格。

The light leakage method of the spiral air duct of the system adopts the method of subsection detection and summary analysis. The spiral air duct of the tested system is not allowed to have multiple slit-shaped obvious light leakage. The light leakage point of the spiral air duct of the low pressure system is not more than 2 every 10 meters, and the average of the 100 meters joints is not more than 16; The spiral air duct of the medium pressure system is qualified if the light leakage point is not more than 1 for every 10 joints and the average number of 100 m joints is not more than 8.

螺旋风管市场上按材质一般分为三类：镀锌螺旋风管、不锈钢螺旋风管以及复合螺旋风管。其中，不锈钢风管质量好，适用性强，但高。目前市场流通广的螺旋风管是镀锌板的。镀锌板螺旋风管，基本是不锈钢螺旋风管的特性。

The spiral duct is generally divided into three categories according to the material in the market: galvanized spiral duct, stainless steel spiral duct and composite spiral duct. Among them, the stainless steel air duct has good quality, strong applicability, but high price. At present, the spiral air duct widely circulated in the market is galvanized sheet. Galvanized sheet spiral duct is basically the characteristic of stainless steel spiral duct.
