通風管道是工業與民用建筑的通風與空調工程用金屬或非金屬管道，是為了使空氣流通，降低有害氣體濃度的一種市政基礎設施。 風管制作與安裝所用板材、型材以及其他主要成品材料，應符合設計及相關產品現行標準的規定，并應用出廠檢驗合格證明，材料進場時應按現行有關標準進行驗收。

Ventilation pipe is a metal or nonmetal pipe for ventilation and air conditioning engineering in industrial and civil buildings. It is a municipal infrastructure for making air circulation and reducing harmful gas concentration. The plank, profile and other main materials of the production and installation of the wind pipe should conform to the national standard of the design and related products, and apply the factory inspection qualification certificate. When the materials enter the field, they should be checked according to the relevant national standards.

從冷化空調產業初始發展到現在近三十年了，凈化空調用的通風管道還基本上停留在原材料原工藝的基礎上，這不能不算是一種遺憾。在鋼鋅鋼板風管的制作方面，大的公司使用機械化生產已不成問題（咬口條縫的氣密性還另當別論），但保溫工序如此的煩瑣、安裝工人如此的勞累，且質量不易保證的現狀依舊沒能解決。

From the initial development of the cold air conditioning industry to the recent thirty years, the ventilation pipes used for purifying the air conditioners basically remain on the basis of raw materials, which is a pity. In the steel making zinc steel sheet air pipe, production using large machinery company has no problem (airtight joint bite tongue is another matter), but the process cumbersome, so the insulation installation workers so tired, and not easy to guarantee the quality of the status quo is still not able to solve.

近年來，一種新的保溫材料一橡塑材料的出現，減輕了工人的勞動強度，可還是沒能擺脫其落后的勞動方式，況且這種材料目前較貴，還不能普遍使用。復合材料的出現在風管產業中是一種進步，是一種發展，復合材料是世界范圍內的一種趨勢，也可以說是工業進步的必然！

In recent years, a new thermal insulation material, the appearance of rubber and plastic material, has lightened the labor intensity of workers, but still can not get rid of its backward labor way. Moreover, the material is expensive at present, and it can not be widely used. The emergence of composite materials is a progress in the wind pipe industry. It is a development. Composite material is a trend in the world, which is also the necessity of industrial progress.
