净化风管的质量直接关系到体系是否到达规划参数和正常运用要求，其制造一般选用工厂集中制造和现场制造两种方法。无论选用哪种制造方法，都要确保制造场地的洁净和关闭，好选用水泥地上或地上铺设金属钢板，其面积不得小于100m?，且满足采光和照明条件，制造完结的净化风管要进行堆积，并进行看守;如果选用现场预制时，要确保预制完结后的风管能够及时运施工现场，尽量削减风管搬运的间隔，这样能够避免运输过程中对风管的污染。

The quality of the purification air duct is directly related to whether the system meets the planning parameters and normal operation requirements. Its manufacturing generally adopts two methods: centralized factory manufacturing and on-site manufacturing. Regardless of the manufacturing method used, it is necessary to ensure the cleanliness and closure of the manufacturing site. It is recommended to use cement or metal steel plates laid on the ground, with an area not less than 100m?, And meet the lighting and lighting conditions, the completed purified air ducts must be stacked and guarded; If on-site prefabrication is used, it is necessary to ensure that the completed air duct can be transported to the construction site in a timely manner, and to minimize the interval between air duct handling, so as to avoid pollution to the air duct during transportation.

风管板厚的挑选

Selection of duct plate thickness

板厚对风管的质量影响较大，为了确保风管的重量，要选用小板厚的风管，可是选用的过程还是和风管的尺度和压力等级有关。在我国，大部分的金属风管选用的是热镀锌钢板和钢带，他的基体是冷轧低碳结构钢板，其抗拉强度>270 ，延伸率>24%，厚度允许差值为d=0.6-1.2mm规模内(±0.07-0.13mm)，由于我国的工业技术和检测技术与国外具有必定差距，国内选用的风管板厚要比国外标准大20%，但跟着我国经济技术的不断开展，许多国内厂商已经有才能出产厚度均匀的板材，因而在风管挑选小板厚时，要挑选差错规模小的钢板，避免造成钢材的糟蹋。

The thickness of the plate has a significant impact on the quality of the air duct. In order to ensure the weight of the air duct, smaller plate thickness air ducts should be selected. However, the selection process is still related to the scale and pressure level of the air duct. In China, the majority of metal air ducts are made of hot-dip galvanized steel plates and steel strips. The base material is cold-rolled low-carbon structural steel plates, with tensile strength>270, elongation>24%, and allowable thickness difference within the range of d=0.6-1.2mm (± 0.07-0.13mm). Due to the certain gap between China's industrial technology and testing technology and foreign countries, the thickness of air duct plates used domestically is 20% larger than foreign standards. However, with the continuous development of China's economy and technology, many domestic manufacturers have been able to produce uniformly thick plates. Therefore, when selecting small plate thicknesses for air ducts, it is necessary to select steel plates with small error sizes to avoid wasting the steel.

此外，从规划角度来看，值得注意的是一个体系能够一起存在几种对应于不同静压等级的风管板厚。在正压风管体系的末端或负压风管的前端，往往能够选用低压风管，而挨近风机的部位能够选用中压或高压风管。

Furthermore, from a planning perspective, it is worth noting that a system can have several duct plate thicknesses corresponding to different static pressure levels together. At the end of a positive pressure air duct system or the front end of a negative pressure air duct, low pressure air ducts can often be used, while medium pressure or high pressure air ducts can be used near the fan.

风管的横向衔接

Horizontal connection of air ducts

横向衔接不仅是连续风管长度的一种手法，也能够起着增强刚度及保持风管地横向尺度的效果。通常横向衔接的方法是角钢法兰衔接，这种衔接方法取决于壁厚，更取决于衔接种类及板壁加固方法。横向衔接中的无法兰衔接在低、中压中等尺度(矩形长边小于1.6m)的风管中的广泛的运用。

Horizontal connection is not only a technique for continuous duct length, but also plays a role in enhancing stiffness and maintaining the horizontal scale of the duct. The usual method of horizontal connection is angle steel flange connection, which depends on the wall thickness, as well as the type of connection and the reinforcement method of the plate wall. The flange free connection in horizontal connection is widely used in low and medium scale (rectangular long side less than 1.6m) air ducts.
